[19:39.640 --> 19:42.480] All right, Jay, tell us about the future of vat-grown meat. | |||
[19:42.480 --> 19:45.620] This isn't the future of vat-grown meat. | |||
[19:45.620 --> 19:50.800] It's more about the difference between plant-based meats and traditional- | |||
[19:50.800 --> 19:51.800] And meat-based meats? | |||
[19:51.800 --> 19:54.640] And meat-based meats that are happening today. | |||
[19:54.640 --> 20:01.640] And the real question here when we compare the two is, how sustainable are these plant-based | |||
[20:01.640 --> 20:03.260] meats? | |||
[20:03.260 --> 20:05.520] What is the profile? | |||
[20:05.520 --> 20:09.840] After doing some research and reading about it, it's pretty interesting how we got to | |||
[20:09.840 --> 20:15.000] plant-based meats, and then we're comparing the energy and resources that it takes to | |||
[20:15.000 --> 20:18.240] create them versus traditional meats. | |||
[20:18.240 --> 20:23.440] So as everybody knows, a lot of people eat meat, and unfortunately, meat demand, if anything, | |||
[20:23.440 --> 20:24.440] it's just going up. | |||
[20:24.440 --> 20:31.640] I have to admit, the older I get, I am way more conscious now about my meat-eating usage. | |||
[20:31.640 --> 20:33.840] I try to lower it as much as possible. | |||
[20:33.840 --> 20:39.300] And as much as I do love meatballs and everything, I don't let myself go there. | |||
[20:39.300 --> 20:42.640] It's like maybe once every couple of months at this point, where it was more like every | |||
[20:42.640 --> 20:44.640] two weeks, which is a big difference for me. | |||
[20:44.640 --> 20:46.120] Every two weeks is fine. | |||
[20:46.120 --> 20:47.360] Yeah. | |||
[20:47.360 --> 20:51.000] The other thing about just eating traditional meat is that it is- | |||
[20:51.000 --> 20:52.560] Once a week is fine. | |||
[20:52.560 --> 20:56.120] It takes a significant toll on the environment. | |||
[20:56.120 --> 21:01.840] Traditional agriculture promotes deforestation, greenhouse gas emissions, air and water pollution. | |||
[21:01.840 --> 21:07.560] So eating meat is just not helping global warming, which is getting worse, and everything | |||
[21:07.560 --> 21:09.200] seems to be getting worse. | |||
[21:09.200 --> 21:14.800] But just as I have to say, because we've covered this topic before, just to give it more nuance | |||
[21:14.800 --> 21:20.240] to that, that doesn't mean zero meat consumption is what's optimal. | |||
[21:20.240 --> 21:23.440] And I know this is controversial, because there are some people who think that that | |||
[21:23.440 --> 21:29.800] is the case, but when we've done a deep dive on this topic, I think it's a fairer summary | |||
[21:29.800 --> 21:34.400] is that we should really have a lot less meat consumption, but not zero, because there's | |||
[21:34.400 --> 21:43.060] an integrated agricultural system where animals are good at converting non-human calories | |||
[21:43.060 --> 21:44.900] into human calories. | |||
[21:44.900 --> 21:48.600] So there can be an efficiency there. | |||
[21:48.600 --> 21:53.840] And they can use land, which is not usable for growing food for people, and they can | |||
[21:53.840 --> 21:57.460] eat food that people can eat and then convert that into food. | |||
[21:57.460 --> 21:59.440] And they produce a lot of fertilizer. | |||
[21:59.440 --> 22:02.440] Half of our food we grow with cattle manure. | |||
[22:02.440 --> 22:06.840] So if they all went away, that would be a huge problem for the agricultural system. | |||
[22:06.840 --> 22:09.160] So you're saying there's a healthy balance in there somewhere. | |||
[22:09.160 --> 22:10.160] Yeah. | |||
[22:10.160 --> 22:11.660] There's probably a sweet spot in there somewhere. | |||
[22:11.660 --> 22:16.000] We're not at it right now, where I think we're just- Demand is requiring that we produce | |||
[22:16.000 --> 22:18.160] more meat than is optimal for the system. | |||
[22:18.160 --> 22:23.040] But not to imply that there's a consensus that we need to go to zero meat consumption. | |||
[22:23.040 --> 22:28.660] And there's studies that show that a meat consumption at certain levels is perfectly | |||
[22:28.660 --> 22:32.240] healthy and is not going to give you a heart attack. | |||
[22:32.240 --> 22:36.660] So approximately 15% of global greenhouse gas emissions come from livestock. | |||
[22:36.660 --> 22:40.460] And like I said, it's only going to go up as demand for meat goes up. | |||
[22:40.460 --> 22:46.640] They're saying that there will be a 15% increase in meat demand in the next decade. | |||
[22:46.640 --> 22:47.640] That is significant. | |||
[22:47.640 --> 22:49.800] That is way more than I would have guessed. | |||
[22:49.800 --> 22:51.840] Greenhouse gases come from where? | |||
[22:51.840 --> 22:55.560] When you're talking about grazing animals like sheep, goats, and cows, right? | |||
[22:55.560 --> 23:00.640] These animals burp methane that comes from them digesting grasses and the like. | |||
[23:00.640 --> 23:04.980] So greenhouse gases also happen to come from chemicals that are used to grow feed. | |||
[23:04.980 --> 23:09.240] So there's lots of things in the industry that are the result of these greenhouse gases. | |||
[23:09.240 --> 23:13.800] So interestingly, chickens and pigs have much lower gas emissions than cows, which I did | |||
[23:13.800 --> 23:14.960] not know. | |||
[23:14.960 --> 23:17.900] They're also better at converting the calories they eat into muscle. | |||
[23:17.900 --> 23:22.120] So for example, when we compare chickens, pigs, and cows, chickens need to eat about | |||
[23:22.120 --> 23:26.560] two pounds of feed for each pound of edible tissue gained. | |||
[23:26.560 --> 23:28.940] Pigs need three to five pounds of feed. | |||
[23:28.940 --> 23:29.940] And cows need- | |||
[23:29.940 --> 23:30.940] Per pound. | |||
[23:30.940 --> 23:31.940] What? | |||
[23:31.940 --> 23:32.940] Per pound. | |||
[23:32.940 --> 23:33.940] Yeah, everything is per pound. | |||
[23:33.940 --> 23:36.360] So a pig needs to eat three to five pounds of feed to make an edible pound. | |||
[23:36.360 --> 23:38.960] And then cows need six to 10 pounds of feed. | |||
[23:38.960 --> 23:39.960] Whoa. | |||
[23:39.960 --> 23:40.960] Yeah. | |||
[23:40.960 --> 23:41.960] So it's a really big difference here. | |||
[23:41.960 --> 23:45.000] Pigs are even worse, they're like 15, 16. | |||
[23:45.000 --> 23:47.000] And fish are close to one to one. | |||
[23:47.000 --> 23:48.000] Wow. | |||
[23:48.000 --> 23:49.000] Yeah, fish are the best. | |||
[23:49.000 --> 23:53.600] Goats and sheep are pretty bad, but they're not consumed in as large quantities across | |||
[23:53.600 --> 23:55.840] the globe as cows. | |||
[23:55.840 --> 24:00.360] Just reading these stats, like eat chicken and fish, that's a good shift in your meat | |||
[24:00.360 --> 24:01.360] right there. | |||
[24:01.360 --> 24:02.840] Just focus on them. | |||
[24:02.840 --> 24:09.760] Cows produce six times more gas than pigs and approximately nine times more than chickens. | |||
[24:09.760 --> 24:14.520] So they are clearly the biggest problem when it comes to grazing animals. | |||
[24:14.520 --> 24:17.920] So today we have products that simulate the taste of meat. | |||
[24:17.920 --> 24:21.160] And they're completely plant-based, and I don't know if you guys have ever tried them, | |||
[24:21.160 --> 24:22.160] but I have. | |||
[24:22.160 --> 24:23.160] I have. | |||
[24:23.160 --> 24:24.160] I've tried them all. | |||
[24:24.160 --> 24:25.160] I'll tell you about it. | |||
[24:25.160 --> 24:26.160] They taste nothing like meat. | |||
[24:26.160 --> 24:27.160] So plant- | |||
[24:27.160 --> 24:28.160] I love Impossible Burger. | |||
[24:28.160 --> 24:29.160] Taste or texture? | |||
[24:29.160 --> 24:30.160] Impossible Burger, Steve, you would not know the difference. | |||
[24:30.160 --> 24:31.160] Oh, absolutely, I know the difference. | |||
[24:31.160 --> 24:32.160] You've had it. | |||
[24:32.160 --> 24:34.280] No, you know the difference, but they're the closest, I think. | |||
[24:34.280 --> 24:35.280] If somebody gave it to- | |||
[24:35.280 --> 24:36.280] I've had them. | |||
[24:36.280 --> 24:38.280] If somebody gave it to me and didn't tell me, I wouldn't even realize it. | |||
[24:38.280 --> 24:39.600] Yeah, for a hamburger, it's fine. | |||
[24:39.600 --> 24:40.600] I mean- | |||
[24:40.600 --> 24:41.600] It's just a little bit weirder. | |||
[24:41.600 --> 24:42.600] That's a separate question. | |||
[24:42.600 --> 24:44.560] I mean, they taste fine. | |||
[24:44.560 --> 24:46.800] I would never confuse it for beef. | |||
[24:46.800 --> 24:47.800] Right. | |||
[24:47.800 --> 24:48.800] But they taste fine. | |||
[24:48.800 --> 24:49.800] I think it tastes better than beef. | |||
[24:49.800 --> 24:50.800] That's different. | |||
[24:50.800 --> 24:51.800] Okay. | |||
[24:51.800 --> 24:52.800] You just have a plain- | |||
[24:52.800 --> 24:53.800] How good it is is a different question than how much- | |||
[24:53.800 --> 24:54.800] What do you have on your hamburger? | |||
[24:54.800 --> 24:55.800] Yeah, the whole shebang. | |||
[24:55.800 --> 24:56.800] Yeah, pickles. | |||
[24:56.800 --> 24:58.640] By the time you put all your condiments, you know, like how much are you, you know. | |||
[24:58.640 --> 25:03.920] So plant-based foods create significantly lower levels of greenhouse gases than meat-based | |||
[25:03.920 --> 25:04.920] foods. | |||
[25:04.920 --> 25:09.080] During the 12-hour show, and this is my anecdote, last year, right, when we do that, a year | |||
[25:09.080 --> 25:12.440] ago last spring, I cooked meatballs for everybody in real time. | |||
[25:12.440 --> 25:18.220] And I also made Ian, because Ian is a vegetarian, I made him plant-based meatballs. | |||
[25:18.220 --> 25:20.960] And I got to tell you, legit, they tasted good. | |||
[25:20.960 --> 25:21.960] They were good. | |||
[25:21.960 --> 25:22.960] They weren't- | |||
[25:22.960 --> 25:23.960] What did you use? | |||
[25:23.960 --> 25:26.440] You know, they weren't beef, but they were a very good flavor and the texture was fantastic. | |||
[25:26.440 --> 25:28.440] So I wasn't really that disappointed in them. | |||
[25:28.440 --> 25:29.680] Jay, what did you use? | |||
[25:29.680 --> 25:31.520] I used Impossible Burger meat. | |||
[25:31.520 --> 25:32.520] Impossible, okay. | |||
[25:32.520 --> 25:33.520] Yeah. | |||
[25:33.520 --> 25:38.840] I've also had Shepherd's Pie made completely out of Impossible Burger, and that was fantastic. | |||
[25:38.840 --> 25:44.360] Because it's heavy with, you know, spices, so it obfuscates the flavor. | |||
[25:44.360 --> 25:49.560] So the point of me saying this is you could use plant-based meats in dishes where, you | |||
[25:49.560 --> 25:53.000] know, there's a lot of spices and everything, like for tacos and things like that. | |||
[25:53.000 --> 25:56.820] Like, you could just think about swapping that in right away because it tastes fantastic. | |||
[25:56.820 --> 26:01.740] So researchers were able to make a plant-based product that has similar traits as real meat | |||
[26:01.740 --> 26:05.000] by figuring out exactly what makes meat meat. | |||
[26:05.000 --> 26:07.020] You know, why does meat taste like meat? | |||
[26:07.020 --> 26:08.520] Why does it have the texture that it has? | |||
[26:08.520 --> 26:10.520] Why does it have the flavors that it has? | |||
[26:10.520 --> 26:15.440] So as an example, many of the products that they use, like coconut oil is a great example. | |||
[26:15.440 --> 26:20.800] They use coconut oil, I believe, in Impossible Burger because it has a similar animal fats | |||
[26:20.800 --> 26:22.880] feel in your mouth. | |||
[26:22.880 --> 26:25.760] Kara, it seems to me like you and I talk about heme quite a bit. | |||
[26:25.760 --> 26:27.800] For some reason, you and I are always chit-chatting about heme. | |||
[26:27.800 --> 26:28.800] Leg hemoglobin. | |||
[26:28.800 --> 26:29.800] Hem! | |||
[26:29.800 --> 26:30.800] Yeah. | |||
[26:30.800 --> 26:31.800] Hemoglobin. | |||
[26:31.800 --> 26:32.800] So this heme is the red liquid. | |||
[26:32.800 --> 26:33.800] Now, this isn't blood. | |||
[26:33.800 --> 26:40.320] It's the red liquid protein that comes out of meats if you have a steak or even ground | |||
[26:40.320 --> 26:41.320] beef. | |||
[26:41.320 --> 26:43.280] If you squeeze it, you see this red liquid come out. | |||
[26:43.280 --> 26:44.280] It's blood, Jay. | |||
[26:44.280 --> 26:45.280] By the way, it's not a red liquid. | |||
[26:45.280 --> 26:46.280] It's not a red liquid. | |||
[26:46.280 --> 26:47.280] It's blood. | |||
[26:47.280 --> 26:48.280] It's not exactly blood, Steve. | |||
[26:48.280 --> 26:49.280] It's a part of blood. | |||
[26:49.280 --> 26:50.280] Yeah, it's a part of blood. | |||
[26:50.280 --> 26:51.280] Watery blood. | |||
[26:51.280 --> 26:52.720] It's a part of blood, and it's pretty amazing. | |||
[26:52.720 --> 26:58.040] When I visited the Impossible headquarters for a TV show, I had to taste leg hemoglobin, | |||
[26:58.040 --> 27:03.680] which is the version that they use, the plant-based version they use in Impossible Meat. | |||
[27:03.680 --> 27:09.800] And it tastes like your mouth is full of blood, like it's gross to just eat on its own. | |||
[27:09.800 --> 27:10.800] It makes you feel weird. | |||
[27:10.800 --> 27:11.800] That's right. | |||
[27:11.800 --> 27:12.800] And you're not supposed to. | |||
[27:12.800 --> 27:16.720] But Kara, the point is, and I want to make this perfectly clear, they made a plant-based | |||
[27:16.720 --> 27:17.720] version of heme. | |||
[27:17.720 --> 27:19.960] Well, all plants have it. | |||
[27:19.960 --> 27:24.800] They just were able to, first they isolated it from soy. | |||
[27:24.800 --> 27:29.120] And then when they realized that the quantity that they could get was so tiny, they started | |||
[27:29.120 --> 27:33.840] genetically engineering yeast to produce it, because it's just so much more efficient to | |||
[27:33.840 --> 27:34.840] do it that way. | |||
[27:34.840 --> 27:35.840] Yeah. | |||
[27:35.840 --> 27:40.520] And so they cultivate these yeast, and then they create reactors that the yeast can multiply | |||
[27:40.520 --> 27:41.520] in. | |||
[27:41.520 --> 27:42.520] And then it cranks. | |||
[27:42.520 --> 27:43.520] This is like insulin. | |||
[27:43.520 --> 27:44.520] You know what I mean? | |||
[27:44.520 --> 27:45.760] This is, by the way, is how insulin is made. | |||
[27:45.760 --> 27:50.380] So taking a close look at how much energy is needed to produce these products will answer | |||
[27:50.380 --> 27:55.560] the overall question that I'm putting to everybody here, is how much better is plant-based meats | |||
[27:55.560 --> 27:57.500] for the environment than regular meat? | |||
[27:57.500 --> 27:59.680] So let me give you guys a little bit of a background here. | |||
[27:59.680 --> 28:03.840] So each ingredient needs to be traced back to where it comes from, from all the processes, | |||
[28:03.840 --> 28:04.840] right? | |||
[28:04.840 --> 28:08.480] There's a ton of processes that they need to get through in order for it to be the final | |||
[28:08.480 --> 28:10.440] version that's found in plant-based meats. | |||
[28:10.440 --> 28:13.420] And this is called life cycle analysis. | |||
[28:13.420 --> 28:16.080] So for example, each ingredient is what? | |||
[28:16.080 --> 28:20.280] They're farmed, because they're plants, they're transported, and then they're processed. | |||
[28:20.280 --> 28:24.520] And in each of those three stages, there's a lot of things happening, and that they had | |||
[28:24.520 --> 28:28.280] to track all of those different steps and every single thing that happens. | |||
[28:28.280 --> 28:33.160] So each step along the way uses fuel, uses water, uses land, uses chemicals, and they | |||
[28:33.160 --> 28:36.840] have to total up all this information for each ingredient, and that gives us the final | |||
[28:36.840 --> 28:37.840] answer. | |||
[28:37.840 --> 28:42.560] But the snag is, because there's always a freaking snag, is that the information wasn't | |||
[28:42.560 --> 28:44.960] readily available to these researchers. | |||
[28:44.960 --> 28:49.800] The companies that make plant-based meats, they're keeping their products and ingredients | |||
[28:49.800 --> 28:54.160] and all of that information to themselves because it's proprietary. | |||
[28:54.160 --> 28:57.560] They don't want to say, here's everything that we do and every single process that we | |||
[28:57.560 --> 29:02.320] use because that is part of their company's business. | |||
[29:02.320 --> 29:03.320] It does make sense. | |||
[29:03.320 --> 29:07.160] I don't think they're doing it for malfeasance. | |||
[29:07.160 --> 29:10.400] They're doing it because they don't want other companies to copy what they're doing. | |||
[29:10.400 --> 29:12.120] It is their intellectual property. | |||
[29:12.120 --> 29:17.160] So scientists had to rely on information that these companies shared about their products. | |||
[29:17.160 --> 29:18.960] That is the one disclosure that I have here. | |||
[29:18.960 --> 29:24.880] I'm just assuming that they gave a relatively accurate rendition of what's actually taking | |||
[29:24.880 --> 29:25.880] place. | |||
[29:25.880 --> 29:32.320] So to get to some numbers, Impossible Burger production only creates 11% of the greenhouse | |||
[29:32.320 --> 29:35.400] gases produced by the same amount of beef. | |||
[29:35.400 --> 29:36.880] That is significantly less. | |||
[29:36.880 --> 29:38.440] Yeah, that's significant. | |||
[29:38.440 --> 29:41.720] Other plant-based meat producers were showing similar numbers as well. | |||
[29:41.720 --> 29:49.600] So compared to pork and chicken, pork was 37% of beef and chicken was 57%, which is | |||
[29:49.600 --> 29:51.600] even better. | |||
[29:51.600 --> 29:56.900] These numbers are pretty significant when you think about the impact on the environment. | |||
[29:56.900 --> 30:02.760] Researchers also found that the amount of water used was only 23% of that in beef, 11% | |||
[30:02.760 --> 30:05.840] used by pork and 24% in chicken for equal amounts of protein. | |||
[30:05.840 --> 30:08.720] So they're dramatically less. | |||
[30:08.720 --> 30:11.120] Land use has huge differences as well. | |||
[30:11.120 --> 30:17.880] Deforested use was 2% of what beef uses for the same amount of protein, 2%, 18% for pork | |||
[30:17.880 --> 30:20.320] and 23% for chicken. | |||
[30:20.320 --> 30:26.240] Land use is important because, you know what, land is very important here because there | |||
[30:26.240 --> 30:31.680] is a potential huge amount of carbon storage that an acre of land can have. | |||
[30:31.680 --> 30:38.840] And when you're deforesting tens of thousands of acres, unfortunately, of the Amazon, you're | |||
[30:38.840 --> 30:42.960] getting rid of an incredible amount of vegetation that's holding a lot of carbon. | |||
[30:42.960 --> 30:43.960] So it all adds up. | |||
[30:43.960 --> 30:48.120] But again, you know, there's always multiple angles here. | |||
[30:48.120 --> 30:52.900] Land that cattle are grazing on is not rainforest, right? | |||
[30:52.900 --> 30:58.820] And so a lot of that land use is not arable land or land that we could be using for agriculture. | |||
[30:58.820 --> 31:07.040] And there is a separate movement, like another way to mitigate the resource use of cows and | |||
[31:07.040 --> 31:20.120] meat, you know, meat-based animals, is to feed them more of the refuse, you know. | |||
[31:20.120 --> 31:22.320] You don't grow grains to feed them. | |||
[31:22.320 --> 31:27.200] You feed them the leftover stuff from human agriculture. | |||
[31:27.200 --> 31:30.680] So that is more of like a circular system. | |||
[31:30.680 --> 31:34.520] So it remains to be seen how far that can go. | |||
[31:34.520 --> 31:37.880] But there is a huge movement in agriculture to do that. | |||
[31:37.880 --> 31:40.440] I just read a recent news item about that. | |||
[31:40.440 --> 31:44.440] Steve, they are clearing Amazon forest for grazing purposes. | |||
[31:44.440 --> 31:51.120] And soybeans are also huge, very high on the list of what's being grown in former Amazon | |||
[31:51.120 --> 31:52.720] forest right now. | |||
[31:52.720 --> 31:54.000] So it is a problem. | |||
[31:54.000 --> 31:56.040] And you know, they're racking back those. | |||
[31:56.040 --> 31:57.320] That's a separate problem. | |||
[31:57.320 --> 32:00.280] Even without animals, that's a problem. | |||
[32:00.280 --> 32:06.160] And you know, even if they're just growing crops, whether animals are in the mix or not, | |||
[32:06.160 --> 32:09.040] that's the worst thing they could be doing is, you know, what they're essentially doing | |||
[32:09.040 --> 32:15.520] is burning down the forest and then planting crops to get all the nutrients out of that. | |||
[32:15.520 --> 32:17.760] And then they move on once they... | |||
[32:17.760 --> 32:19.600] It's not even burning down a forest. | |||
[32:19.600 --> 32:24.000] They're like burning down libraries, essentially, I mean, because you've got genetic diversity | |||
[32:24.000 --> 32:26.040] in those rainforests. | |||
[32:26.040 --> 32:27.040] And they're isolated. | |||
[32:27.040 --> 32:31.000] You have a genetic diversified area that is unique. | |||
[32:31.000 --> 32:35.960] And once that's gone, that is gone, it's millions of years of evolution, now gone that we will | |||
[32:35.960 --> 32:36.960] never retrieve. | |||
[32:36.960 --> 32:40.480] There could be amazing drugs in there, amazing genetic information that is gone. | |||
[32:40.480 --> 32:44.160] So it's so far worse than just burning down trees and stuff. | |||
[32:44.160 --> 32:48.920] There are alternatives, like you can farm the forest, right? | |||
[32:48.920 --> 32:55.520] You can plant and cultivate and whatever things that will grow within the forest without having | |||
[32:55.520 --> 32:57.200] to destroy the forest itself. | |||
[32:57.200 --> 33:00.200] Yeah, like castanhas, like Brazil nut trees, they're really sustainable. | |||
[33:00.200 --> 33:05.560] It's a great way to harvest things that are already growing there and not disrupt the | |||
[33:05.560 --> 33:06.560] ecosystem. | |||
[33:06.560 --> 33:11.460] And they could also use the land they're already using for farming better by planting things | |||
[33:11.460 --> 33:15.600] which regenerate the soil that are also cash crops, you know. | |||
[33:15.600 --> 33:17.080] But so they're just not doing it smartly. | |||
[33:17.080 --> 33:18.240] They're not doing it well. | |||
[33:18.240 --> 33:22.520] Well, in some areas, people really are doing it smartly, and in other areas there's too | |||
[33:22.520 --> 33:27.540] much demand and the cost is too high and individuals are going to do what they need to do to maintain | |||
[33:27.540 --> 33:28.540] their livelihood. | |||
[33:28.540 --> 33:29.540] Absolutely. | |||
[33:29.540 --> 33:31.880] So this is way bigger than the boots on the ground in the Amazon. | |||
[33:31.880 --> 33:36.480] It's the pressure from countries like ours asking for tropical hardwoods and asking for | |||
[33:36.480 --> 33:41.240] more crops to be grown and more animals to be produced in those areas. | |||
[33:41.240 --> 33:46.600] Jay, I think it's important to note because I've been looking at the comments that a lot | |||
[33:46.600 --> 33:54.640] of these lab grown or synthetic meats that try to emulate real meat, the target audience | |||
[33:54.640 --> 33:59.600] is not people who are already not eating meat because you hear a lot of times people going, | |||
[33:59.600 --> 34:00.600] it grosses me out. | |||
[34:00.600 --> 34:01.700] It tastes too much like real meat. | |||
[34:01.700 --> 34:03.960] I don't want to eat fake meat. | |||
[34:03.960 --> 34:04.960] It's not for you. | |||
[34:04.960 --> 34:05.960] Yeah. | |||
[34:05.960 --> 34:10.120] The idea that like the CEO of Impossible when I interviewed him, I think Pat Brown is his | |||
[34:10.120 --> 34:15.360] name, he was very clear, I wanted to develop this so that I could give an alternative to | |||
[34:15.360 --> 34:20.400] people who are doing the environmental harm, people who are eating large quantities of | |||
[34:20.400 --> 34:21.400] meat. | |||
[34:21.400 --> 34:22.400] Exactly. | |||
[34:22.400 --> 34:25.720] So that they have an option to do better without giving up what they love. | |||
[34:25.720 --> 34:32.840] So I think the meta problem here is that, yeah, there are smart agricultural practices. | |||
[34:32.840 --> 34:35.200] There are optimal agricultural practices. | |||
[34:35.200 --> 34:39.000] We can get the system to be more circular and work together better. | |||
[34:39.000 --> 34:44.460] But it's not like there is a world agricultural organization that actually controls what every | |||
[34:44.460 --> 34:46.160] farmer does. | |||
[34:46.160 --> 34:50.500] And so what you have is individual farmers making individual decisions that are in their | |||
[34:50.500 --> 34:52.840] best interest. | |||
[34:52.840 --> 34:57.440] And a lot of the times it's like, well, they're making decisions so they don't starve. | |||
[34:57.440 --> 35:01.160] They're making decisions so that they don't lose money doing what they're doing. | |||
[35:01.160 --> 35:04.560] The margins are so razor thin with agriculture. | |||
[35:04.560 --> 35:11.000] And so they're not necessarily doing what's optimal for the whole system, but we're at | |||
[35:11.000 --> 35:15.720] a point with eight billion people on the planet where we're already basically using up all | |||
[35:15.720 --> 35:20.800] the arable land and because of global warming, where we need the whole system to be efficient | |||
[35:20.800 --> 35:22.020] together. | |||
[35:22.020 --> 35:26.760] And that's really what we're talking about is moving towards an integrated system that's | |||
[35:26.760 --> 35:28.640] coordinated and that's optimal. | |||
[35:28.640 --> 35:35.340] And that may mean having to pay poor people to not do stuff or paying to give them better | |||
[35:35.340 --> 35:38.760] ways to do things or integrating it better. | |||
[35:38.760 --> 35:43.240] But again, individuals will make smart decisions for themselves that are not good for the whole | |||
[35:43.240 --> 35:44.240] system. | |||
[35:44.240 --> 35:45.240] That's really the problem. | |||
[35:45.240 --> 35:46.240] Right. | |||
[35:46.240 --> 35:47.240] That's why we have poaching. | |||
[35:47.240 --> 35:49.660] That's why we have gold mining in the Amazon, because it's the only option these people | |||
[35:49.660 --> 35:52.120] have. | |||
[35:52.120 --> 35:56.520] I think it's fair to note here, there are some drawbacks to plant-based meats. | |||
[35:56.520 --> 36:02.000] Right now they cost 43% more than products that they're trying to replace, which is a | |||
[36:02.000 --> 36:03.000] lot. | |||
[36:03.000 --> 36:06.880] And I did go on, I did some online searching and verified that that's true. | |||
[36:06.880 --> 36:11.080] Which is another point, like if you're like a poor farmer in Africa, sometimes animal | |||
[36:11.080 --> 36:14.580] protein is the cheapest, best protein you can get access to. | |||
[36:14.580 --> 36:16.840] And that's very important for certain people. | |||
[36:16.840 --> 36:21.000] Again, we can't just look at this from our perspective where like we have no issues with | |||
[36:21.000 --> 36:24.040] getting enough food or calories or high quality proteins or stuff. | |||
[36:24.040 --> 36:28.100] When most of the world is living on the edge, we have to be very careful about any changes | |||
[36:28.100 --> 36:29.100] that we make. | |||
[36:29.100 --> 36:34.680] And right now, plant-based meats are only 1% of the market, which is basically almost | |||
[36:34.680 --> 36:35.760] nothing. | |||
[36:35.760 --> 36:41.880] I would just like to say at this point, eat green leafy vegetables, eat beans, eat grains. | |||
[36:41.880 --> 36:45.320] This is much healthier than predominantly eating meats. | |||
[36:45.320 --> 36:48.920] Well, it's all about balance, but we definitely should eat more of that, and we are generally | |||
[36:48.920 --> 36:49.920] in the West. | |||
[36:49.920 --> 36:53.260] Well, everyone, we're going to take a quick break from our show to talk about our sponsor | |||
[36:53.260 --> 36:54.760] this week, BetterHelp. | |||
[36:54.760 --> 36:57.120] Yeah, and let's not sugarcoat it, everyone. | |||
[36:57.120 --> 36:59.560] It's a tough time out there and a lot of people are struggling. | |||
[36:59.560 --> 37:06.400] And if you are struggling and you have never decided to take the plunge and talk to somebody, | |||
[37:06.400 --> 37:08.200] maybe now is the time. | |||
[37:08.200 --> 37:11.640] It's so important to prioritize our mental health. | |||
[37:11.640 --> 37:16.120] If we put that first, everything else really can follow and BetterHelp can help you with | |||
[37:16.120 --> 37:17.120] that. | |||
[37:17.120 --> 37:19.520] You know, I myself work as a therapist and I also go to therapy. | |||
[37:19.520 --> 37:24.320] And I can tell you that online therapy has been really, really beneficial for a lot of | |||
[37:24.320 --> 37:27.800] folks where it's, you know, it fits better within your day. | |||
[37:27.800 --> 37:31.780] You have limitations to be able to get in the car and drive somewhere. | |||
[37:31.780 --> 37:35.440] Being able to talk to somebody online can be really a lifesaver. | |||
[37:35.440 --> 37:37.960] And it's the model that I'm now using all the time. | |||
[37:37.960 --> 37:43.480] Yeah, Kara, you could do it on your phone or, you know, your iPad if you want to, any | |||
[37:43.480 --> 37:45.360] way that you connect with the video. | |||
[37:45.360 --> 37:49.400] You can even live chat with therapy sessions so you don't have to see anyone on camera | |||
[37:49.400 --> 37:50.400] if you don't want to. | |||
[37:50.400 --> 37:55.300] And the other great thing is you could be matched with a therapist in under 48 hours. | |||
[37:55.300 --> 38:00.880] Our listeners get 10% off their first month at BetterHelp.com slash SGU. | |||
[38:00.880 --> 38:04.480] That's Better H-E-L-P dot com slash SGU. | |||
[38:04.480 --> 38:06.720] All right, guys, let's get back to the show. | |||

Introduction, Hurricane Ian, new SGU Book
Voice-over: You're listening to the Skeptics' Guide to the Universe, your escape to reality.
[00:12.920 --> 00:18.680] Today is Saturday, September 24th, 2022, and this is your host, Stephen Novella.
[00:18.680 --> 00:20.240] Joining me this week are Bob Novella.
[00:20.240 --> 00:21.240] Hey, everybody.
[00:21.240 --> 00:22.240] Kara Santamaria.
[00:22.240 --> 00:23.240] Howdy.
[00:23.240 --> 00:24.240] Jay Novella.
[00:24.240 --> 00:25.240] Hey, guys.
[00:25.240 --> 00:26.240] And Evan Bernstein.
[00:26.240 --> 00:27.240] Good evening, everyone.
[00:27.240 --> 00:31.120] We are recording this episode live in SGU Studios.
[00:31.120 --> 00:37.600] Kara is joining us remotely from Florida, battening down the hatches while a hurricane
[00:37.600 --> 00:39.080] is bearing down on her.
[00:39.080 --> 00:40.240] How are you doing down there, Kara?
[00:40.240 --> 00:45.480] Well, it's not here yet, but I'm supposed to go home to LA next Thursday, and then I
[00:45.480 --> 00:49.400] just found out right after I booked the tickets that we're quite probably going to be hit
[00:49.400 --> 00:52.560] with a category three hurricane on Wednesday.
[00:52.560 --> 00:54.080] It'll be my first ever.
[00:54.080 --> 01:00.880] So I did tornadoes in Texas, earthquakes in California, hurricanes now in Florida.
[01:00.880 --> 01:02.680] Just need to move on to an active volcano.
[01:02.680 --> 01:03.680] Yeah, there you go.
[01:03.680 --> 01:07.960] Now, Kara, you know according to Florida rules, you need to be mowing your lawn when that
[01:07.960 --> 01:10.000] hurricane hits, right?
[01:10.000 --> 01:14.160] You need to be outside doing something as if there's no danger.
[01:14.160 --> 01:16.560] Right, and my cow needs to be untrimmed.
[01:16.560 --> 01:17.560] Right.
[01:17.560 --> 01:21.440] Because the low pressure of the system raises the grass a little straighter, makes it easier
[01:21.440 --> 01:22.440] to cut.
[01:22.440 --> 01:23.680] So I mean, it's kind of an obvious move.
[01:23.680 --> 01:28.520] Now, NASA is still planning on launching Artemis on Tuesday.
[01:28.520 --> 01:29.520] Did they finally scrub it?
[01:29.520 --> 01:30.520] That's so not going to happen.
[01:30.520 --> 01:31.520] Oh, yeah.
[01:31.520 --> 01:34.640] Well, they like to wait till the last minute because sometimes these things zig instead
[01:34.640 --> 01:38.560] of zag, and they don't want to miss their window, but I guess the latest update is they
[01:38.560 --> 01:39.560] just scrubbed it.
[01:39.560 --> 01:40.560] Not surprising.
[01:40.560 --> 01:42.280] I thought that was a little bit of wishful thinking.
[01:42.280 --> 01:46.360] So part of the reason why we are recording this episode, and there'll be another episode
[01:46.360 --> 01:51.680] that we're recording as part of a live stream, is because our second book, The Skeptic's
[01:51.680 --> 01:58.440] Guide to the Future, is coming out in just three days on September 27th.
[01:58.440 --> 02:03.060] So this book is The Skeptic's Guide to the Future, but Bob Jay and I wrote this one.
[02:03.060 --> 02:09.560] This was a ton of fun to research, to talk about, to design, figure out what goes into
[02:09.560 --> 02:11.200] it, to write.
[02:11.200 --> 02:13.560] We've already had a few interviews about it.
[02:13.560 --> 02:16.320] It's super fun to talk about.
[02:16.320 --> 02:22.680] Really what we do in this book is we go through first the history of futurism, right?
[02:22.680 --> 02:28.600] So previous attempts at predicting the future and how did they do, what did they get wrong,
[02:28.600 --> 02:31.160] what patterns of wrongness are there?
[02:31.160 --> 02:36.080] We talk about futurism fallacies, the common mistakes that futurists make over and over
[02:36.080 --> 02:37.080] again.
[02:37.080 --> 02:40.760] We looked a little bit into futurism as an academic discipline to see what they're saying
[02:40.760 --> 02:42.480] there, et cetera.
[02:42.480 --> 02:48.040] And then the meat of the book is we talk about the cutting edge technologies, where they're
[02:48.040 --> 02:53.200] coming from, where they are now, and then we try to extrapolate them into the future,
[02:53.200 --> 02:59.200] the near future, the medium future, and then the distant future when those technologies
[02:59.200 --> 03:00.680] are fully mature.
[03:00.680 --> 03:04.240] What is the ultimate potential of these technologies?
[03:04.240 --> 03:05.320] We had fun.
[03:05.320 --> 03:10.400] That was the fun part because when we discussed what is this technology going to look like
[03:10.400 --> 03:15.960] fifty, a hundred, a thousand years from now, then we took the opportunity to write some
[03:15.960 --> 03:21.360] science fiction to illustrate that technology in use, which I thought came out really well.
[03:21.360 --> 03:27.640] That was a ton of fun discussing what that could look like in use.
[03:27.640 --> 03:28.640] We call them vignettes.
[03:28.640 --> 03:30.720] They're not even really a full short story.
[03:30.720 --> 03:33.400] It's just a glimpse of the future.
[03:33.400 --> 03:38.400] And they bring into lots of different technologies that we had just discussed or that we're about
[03:38.400 --> 03:39.400] to discuss in the book.
[03:39.400 --> 03:42.440] So it's not just one tech, but a bunch of them all in one story.
[03:42.440 --> 03:45.800] And that, of course, is one of the main themes of the book.
[03:45.800 --> 03:50.720] One of the futurism fallacies is to think that how will this one technology look in
[03:50.720 --> 03:51.720] the future?
[03:51.720 --> 03:56.120] But you can't think about it that way because by the time you get to that point that you're
[03:56.120 --> 04:00.720] talking about, all other technologies will have been advancing in the background.
[04:00.720 --> 04:06.260] So I say, well, what will fusion power look like in fifty years?
[04:06.260 --> 04:10.360] You can't talk about that without also talking about what solar power is going to look like
[04:10.360 --> 04:15.160] in fifty years and all other sources of energy because it's always going to be compared to
[04:15.160 --> 04:17.480] all of the other options.
[04:17.480 --> 04:22.880] Or if we talk a lot about space travel and we think, oh, by the time we get, you know,
[04:22.880 --> 04:27.400] here are the problems that we'll be facing with spending a lot of time in space or interstellar
[04:27.400 --> 04:28.400] travel.
[04:28.400 --> 04:31.760] Yeah, but by the time we get that, we might be cyborgs.
[04:31.760 --> 04:32.760] We probably will be.
[04:32.760 --> 04:34.340] We'll be genetically engineered.
[04:34.340 --> 04:38.280] We may just, you know, transfer into a robot for the trip, you know, or whatever.
[04:38.280 --> 04:40.680] Like you have to think about all the other things that are happening.
[04:40.680 --> 04:41.680] It's not going to be us.
[04:41.680 --> 04:42.680] Right.
[04:42.680 --> 04:43.680] Right.
[04:43.680 --> 04:44.680] It's not going to be us in the future.
[04:44.680 --> 04:45.680] That's what we want.
[04:45.680 --> 04:46.680] We want to imagine us in the future.
[04:46.680 --> 04:47.680] But that's not what's going to be happening.
[04:47.680 --> 04:52.200] And if you look at previous predictions of the future and futurists, that's a classic
[04:52.200 --> 04:53.200] mistake.
[04:53.200 --> 04:57.440] They take themselves, their culture, and they just put it, plop it into place with this
[04:57.440 --> 04:58.880] new fancy technology.
[04:58.880 --> 05:01.800] And that's a classic mistake that you see over and over and over.
[05:01.800 --> 05:02.800] Right.
[05:02.800 --> 05:06.400] Because part of, quote unquote, predicting the future is thinking about how people are
[05:06.400 --> 05:08.240] going to interact with that technology.
[05:08.240 --> 05:11.660] And again, we imagine how we're going to interact with that technology.
[05:11.660 --> 05:14.600] But I think we're living at a very interesting time.
[05:14.600 --> 05:21.480] Probably our generation, maybe more than any other generation, has a firsthand example of,
[05:21.480 --> 05:27.040] like for those of us who have kids, like our kids have a different relationship with technology
[05:27.040 --> 05:28.040] than we do.
[05:28.040 --> 05:29.040] Oh my gosh.
[05:29.040 --> 05:30.040] Right.
[05:30.040 --> 05:31.040] They use social media.
[05:31.040 --> 05:32.040] They use their smartphone.
[05:32.040 --> 05:34.280] They think about these things differently than we do.
[05:34.280 --> 05:37.000] They think about it differently.
[05:37.000 --> 05:38.720] They prioritize different things.
[05:38.720 --> 05:43.760] My daughters rarely, if ever, use their phone as a phone.
[05:43.760 --> 05:46.360] It's not really a phone for them.
[05:46.360 --> 05:51.840] They use it way more to text or to communicate on certain social media apps or whatever.
[05:51.840 --> 05:52.840] Wait, Steve.
[05:52.840 --> 05:53.840] Do you use your phone?
[05:53.840 --> 05:54.840] You make phone calls?
[05:54.840 --> 05:55.840] Yes.
[05:55.840 --> 05:56.840] Yeah.
[05:56.840 --> 05:57.840] Yeah.
[05:57.840 --> 05:58.840] What?
[05:58.840 --> 06:02.480] Actually, I was telling Rachel, when I was her age, I had two means of communicating
[06:02.480 --> 06:03.480] with people.
[06:03.480 --> 06:06.520] I wrote them a letter or I picked up a phone and called them.
[06:06.520 --> 06:07.520] And that was it.
[06:07.520 --> 06:08.520] Or you met them in person.
[06:08.520 --> 06:09.520] Yeah.
[06:09.520 --> 06:10.520] That sucked.
[06:10.520 --> 06:11.520] Or you met them in person.
[06:11.520 --> 06:14.440] But short of that, because I moved around the country a lot, I had to want to communicate
[06:14.440 --> 06:15.440] with my friends.
[06:15.440 --> 06:16.680] So we talked about how that happened.
[06:16.680 --> 06:22.360] I said, I wrote letters and made phone calls that cost $15 for 30 minutes.
[06:22.360 --> 06:24.160] That's how you communicated with people across the country.
[06:24.160 --> 06:25.160] That was it.
[06:25.160 --> 06:28.040] And I remember worrying about the cost of making a phone call.
[06:28.040 --> 06:29.040] Absolutely.
[06:29.040 --> 06:32.160] You had to call it off-peak hours so that you wouldn't get charged the prime rate, because
[06:32.160 --> 06:38.080] my parents would kill me if they found out I ran up a $50 phone bill for a call to my
[06:38.080 --> 06:40.040] friend back at the other side of the country.
[06:40.040 --> 06:44.560] I think Steve's a little bit anomalous, though, because I definitely use my phone a lot.
[06:44.560 --> 06:47.560] And I definitely don't use it mostly for making phone calls.
[06:47.560 --> 06:50.800] There's just so much other stuff, the obvious stuff that I do.
[06:50.800 --> 06:51.800] Oh, yeah.
[06:51.800 --> 06:57.240] I mean, a smartphone is probably the phone app is one of the least used aspects of it.
[06:57.240 --> 06:58.240] Absolutely.
[06:58.240 --> 07:00.240] My smartphone is my handheld computer.
[07:00.240 --> 07:01.240] That's not my point.
[07:01.240 --> 07:02.960] If it disappeared, could we get by without it?
[07:02.960 --> 07:04.840] I do call and accept phone calls.
[07:04.840 --> 07:06.160] It is still my phone.
[07:06.160 --> 07:08.480] My daughters, they turned off their ringer.
[07:08.480 --> 07:11.600] They don't use it at all as a phone.
[07:11.600 --> 07:17.440] My phone is on silent with no notifications ever for my mental health, but I'm curious.
[07:17.440 --> 07:21.120] So the only time I ever talk on the phone, and I guess that's changed a little since
[07:21.120 --> 07:26.000] I've been in Florida without a car, but in California, the only time I would have conversations
[07:26.000 --> 07:28.920] was when I was driving long distances.
[07:28.920 --> 07:30.760] Does anybody else have that same vibe?
[07:30.760 --> 07:32.640] The only time I talk to people is in the car.
[07:32.640 --> 07:36.000] That's not the only time, but that's definitely a huge opportunity because you're just sitting
[07:36.000 --> 07:42.480] there doing nothing, and you could talk to people now that it's easy when you route the
[07:42.480 --> 07:44.640] phone through your car so you're not holding it.
[07:44.640 --> 07:47.320] Where are you talking to people, then, if you're not on the phone?
[07:47.320 --> 07:50.320] Are you not having conversations?
[07:50.320 --> 07:54.720] Just communicating virtual time, yeah, with texts and emails and whatever.
[07:54.720 --> 07:57.800] I'm definitely more of a phone talker than a texter.
[07:57.800 --> 08:05.840] And then if I'm missing somebody and we want to have quality time together, then we FaceTime.
[08:05.840 --> 08:11.320] Well I primarily use my phone to get angry at the internet, I think, if I summarize my
[08:11.320 --> 08:12.320] interaction.
[08:12.320 --> 08:14.240] She's an angry old Facebook man.
[08:14.240 --> 08:17.840] I am pissed off at basically everybody that uses social media.
[08:17.840 --> 08:21.600] I log in and I'm instantly furious with what I see.
[08:21.600 --> 08:28.860] But this is a classic sort of futurism fallacy, again, in that past futurists pretty much
[08:28.860 --> 08:36.400] unanimously imagined that in the future, the amorphous future, when the technology existed,
[08:36.400 --> 08:39.720] people will video call, right?
[08:39.720 --> 08:40.840] And now we have...
[08:40.840 --> 08:41.840] We assumed it.
[08:41.840 --> 08:47.560] Even we did years ago, 30 years ago, that was the obvious next step for phones.
[08:47.560 --> 08:56.040] So we have, now we have, you could video call, audio call, or text, and people prefer texting
[08:56.040 --> 08:57.920] to audio and audio to video.
[08:57.920 --> 09:01.360] It's the exact opposite of what everyone predicted prior to...
[09:01.360 --> 09:04.160] Or, I mean, I think they all have different uses.
[09:04.160 --> 09:05.160] But that's the thing.
[09:05.160 --> 09:09.780] Until you put a technology in the hands of billions of people and see how they use it,
[09:09.780 --> 09:12.080] it's hard to predict.
[09:12.080 --> 09:17.320] Most futurists think we're going to use future technology like we use current technology.
[09:17.320 --> 09:19.560] So here's another fun example.
[09:19.560 --> 09:26.480] When commercial airplane travel was first, first becoming a thing, futurists imagined
[09:26.480 --> 09:31.280] that it would evolve into these gigantic luxury airplanes.
[09:31.280 --> 09:32.280] Flying hotels almost.
[09:32.280 --> 09:34.320] They were flying cruise ships, right?
[09:34.320 --> 09:35.620] Right, like luxury liners.
[09:35.620 --> 09:38.360] They were like luxury liners in the air.
[09:38.360 --> 09:45.080] That is how they were imagined because they assumed that the use and priorities, it's
[09:45.080 --> 09:50.600] all about luxury, right, would hold true even to, would translate to this new technology.
[09:50.600 --> 09:54.720] And they didn't anticipate, like, no, people are going to want to get there fast and cheap.
[09:54.720 --> 10:03.320] And now we've gone so far the other direction where we're crammed into these tiny seats.
[10:03.320 --> 10:07.720] And you could pay through the nose for a first class seat where you get a slightly bigger
[10:07.720 --> 10:08.720] seat.
[10:08.720 --> 10:09.720] Makes a difference.
[10:09.720 --> 10:13.840] Or lots of other airlines, lots of other airlines I've seen where you can go super ultra mega
[10:13.840 --> 10:20.760] first class where you literally get a TV this big, a little room, and a foot rub.
[10:20.760 --> 10:24.960] Somebody comes in and gives you a foot rub, but you're spending $40,000.
[10:24.960 --> 10:26.920] How many people are going to really do that?
[10:26.920 --> 10:32.080] And Bob, even that's nothing compared to the luxury liners that they imagined where it
[10:32.080 --> 10:36.080] was like you're living in a hotel while you're on the plane.
[10:36.080 --> 10:37.080] Completely different.
[10:37.080 --> 10:38.080] Yeah.
[10:38.080 --> 10:41.080] Kara, have you ever called the remote control the clicker?
[10:41.080 --> 10:42.080] I have.
[10:42.080 --> 10:43.080] Okay.
[10:43.080 --> 10:44.080] Yeah.
[10:44.080 --> 10:45.080] I have.
[10:45.080 --> 10:46.080] Yeah.
[10:46.080 --> 10:47.080] To the original remote device.
[10:47.080 --> 10:48.080] That's what it was tethered.
[10:48.080 --> 10:49.080] Which made a click noise.
[10:49.080 --> 10:50.080] No, no, no.
[10:50.080 --> 10:51.080] Yeah.
[10:51.080 --> 10:52.080] You would make a literal clicking sound.
[10:52.080 --> 10:53.080] The frequency, right.
[10:53.080 --> 10:57.720] When you hit the button, it would hit a, like, tuning fork rod, which would vibrate at a
[10:57.720 --> 11:01.920] specific frequency, and the TV would respond to that frequency.
[11:01.920 --> 11:03.640] So you had, like, three or four controls.
[11:03.640 --> 11:04.640] Three buttons.
[11:04.640 --> 11:05.640] That's it.
[11:05.640 --> 11:09.240] Yeah, like three or four buttons, like volume, you know, up, down, channel, up, down, on,
[11:09.240 --> 11:10.240] off.
[11:10.240 --> 11:11.240] That's it.
[11:11.240 --> 11:12.240] That's it.
[11:12.240 --> 11:14.560] Yeah, so people still call it the clicker.
[11:14.560 --> 11:15.560] We also still say tape.
[11:15.560 --> 11:17.120] Like, we're going to tape something.
[11:17.120 --> 11:18.120] Right.
[11:18.120 --> 11:19.120] Yeah.
[11:19.120 --> 11:20.120] When tape is nowhere in the loop anymore.
[11:20.120 --> 11:23.480] But they make it, those things, people understand what they mean.
[11:23.480 --> 11:24.480] Yeah.
[11:24.480 --> 11:25.480] Yeah.
[11:25.480 --> 11:26.480] Yeah.
[11:26.480 --> 11:29.800] And, you know, I promise all of you that are young, you'll feel old one day, too.
[11:29.800 --> 11:33.720] Whatever you think is normal now, it won't be in 30 years, and you'll be doing the same
[11:33.720 --> 11:34.720] thing.
[11:34.720 --> 11:35.720] Goddammit.
[11:35.720 --> 11:39.400] And it will probably just speed up.
[11:39.400 --> 11:40.400] Yeah.
[11:40.400 --> 11:41.400] Oh, gosh.
[11:41.400 --> 11:47.680] A 25-year-old and a 20-year and a 20-year-old might find, see dramatic differences as the
[11:47.680 --> 11:53.040] pace of increase, you know, accelerates, as it probably will.
[11:53.040 --> 11:56.960] And we're just skimming the surface of this book.
[11:56.960 --> 12:01.300] The third section of the book goes into science fiction technology.
[12:01.300 --> 12:06.560] So we go beyond actual technology where, like, the roots of it, even if, like, the beginnings
[12:06.560 --> 12:12.340] of it already exist, even if it's just a proof of concept or a theory at this point.
[12:12.340 --> 12:18.560] And then we just talk about crazy sci-fi tech and discuss, like, is this even possible?
[12:18.560 --> 12:20.360] Like lightsabers, you know, things like that.
[12:20.360 --> 12:21.360] Anti-gravity.
[12:21.360 --> 12:25.240] Is it even possible that we could possibly make a lightsaber?
[12:25.240 --> 12:26.440] And what would that be like?
[12:26.440 --> 12:31.240] And can you think about it, like, by the time, if you could make a lightsaber, that technology
[12:31.240 --> 12:33.720] would be useful for so many other things.
[12:33.720 --> 12:35.320] It would be so powerful.
[12:35.320 --> 12:36.320] That power source.
[12:36.320 --> 12:37.320] It would be a game changer.
[12:37.320 --> 12:39.920] I could plug that into my building and run my building off of that.
[12:39.920 --> 12:40.920] Yeah, right.
[12:40.920 --> 12:41.920] Exactly.
[12:41.920 --> 12:47.080] That's like the transporter, you know, like in Star Trek, you know, like, that one invention
[12:47.080 --> 12:48.080] would change reality.
[12:48.080 --> 12:50.680] It would change everybody's life.
[12:50.680 --> 12:53.320] In ways that, you know, would be impossible to predict.
[12:53.320 --> 12:54.320] Yeah.
[12:54.320 --> 12:58.200] Or my favorite, and we go into this in the book, the holodeck.
[12:58.200 --> 13:03.640] If you could do that, why would you confine that to one little room, right?
[13:03.640 --> 13:08.120] Why wouldn't the whole ship be a holodeck, right?
[13:08.120 --> 13:13.480] It would configure itself as needed to whatever functionality you needed anywhere on the ship,
[13:13.480 --> 13:18.240] except, you know, with the only exception of intricate machines that it couldn't make.
[13:18.240 --> 13:20.080] Assuming you had limitless power at your disposal.
[13:20.080 --> 13:22.680] Every room would become a room of requirement.
[13:22.680 --> 13:23.680] Yeah.
[13:23.680 --> 13:24.680] Basically.
[13:24.680 --> 13:25.680] Yeah.
[13:25.680 --> 13:26.680] Pretty much.
[13:26.680 --> 13:30.120] And all you would need is, give me a holodeck and a replicator, and I'm good.
[13:30.120 --> 13:31.120] I'm done.
[13:31.120 --> 13:32.120] Yeah.
[13:32.120 --> 13:33.120] See you.
[13:33.120 --> 13:34.120] See you at that point.
[13:34.120 --> 13:35.120] See you at that point.
[13:35.120 --> 13:39.160] You go into Bob's holodeck, like, 50 years later, and it would be like a Halloween planet.
[13:39.160 --> 13:40.160] Yeah.
[13:40.160 --> 13:41.160] He would have constructed, right?
[13:41.160 --> 13:42.160] Also, don't go in there with a black light.
[13:42.160 --> 13:43.160] Oh, my God.
[13:43.160 --> 13:44.160] I saw the joke, and I took it.
[13:44.160 --> 13:45.160] Yeah.
[13:45.160 --> 13:46.160] Holy shit.
[13:46.160 --> 13:54.800] We encourage anyone who's interested in any of the things we're talking about, anything
[13:54.800 --> 13:59.400] about futurism and future technology and existing technology and the history of technology,
[13:59.400 --> 14:04.200] all of that, and sci-fi stuff, to pre-order the book, The Skeptic's Guide to the Future.
[14:04.200 --> 14:09.320] If you're listening to this after September 27th, you can order the book directly, and
[14:09.320 --> 14:11.800] they'll send it to you.
[14:11.800 --> 14:15.480] You can get to the links on the SGU page.
[14:15.480 --> 14:19.960] You go to the, you know, slash books, and then that takes you to the publisher who has
[14:19.960 --> 14:23.040] all the actual links to specific sellers.
[14:23.040 --> 14:27.880] I also will remind you that this is our second book.
[14:27.880 --> 14:29.840] Don't forget about The Skeptic's Guide to the Universe.
[14:29.840 --> 14:30.840] That's our first book.
[14:30.840 --> 14:32.640] It's still selling quite well, actually.
[14:32.640 --> 14:33.640] Yeah.
[14:33.640 --> 14:35.840] Let's get to some actual content.
[14:35.840 --> 14:36.840] Bob.
[14:36.840 --> 14:37.840] Oh, boy.
Forgotten Superheroes of Science (14:37)
- Raye Jean Montague, American naval engineer credited with creating the first computer-generated rough draft of a U.S. naval ship
[14:37.840 --> 14:38.840] You're going to do a Forgotten Superhero of Science.
[14:38.840 --> 14:39.840] Yeah.
[14:39.840 --> 14:40.840] I haven't done this in a while.
[14:40.840 --> 14:42.940] So, yes, Forgotten Superheroes of Science.
[14:42.940 --> 14:51.680] This is Ray Jean Montague, 1935 to 2018, naval engineer and the first female program manager
[14:51.680 --> 14:54.120] of ships in the United States Navy.
[14:54.120 --> 14:59.160] In her own words, she said, I'm known as the first person to design a ship using the computer.
[14:59.160 --> 15:00.160] Cool.
[15:00.160 --> 15:04.920] Montague was inspired early in life when, for her, you know, her scientific career.
[15:04.920 --> 15:09.480] When she was seven, I believe in 1940, her grandfather took her on a tour of a captured
[15:09.480 --> 15:10.480] German sub.
[15:10.480 --> 15:11.480] Wow.
[15:11.480 --> 15:15.560] And she said, she's quoted as saying about that experience, I looked through the periscope
[15:15.560 --> 15:17.840] and saw all these dials and mechanisms.
[15:17.840 --> 15:23.080] And I said to the guy who was giving the tour, what do you have to know to do this?
[15:23.080 --> 15:26.020] And he replied, oh, you'd have to be an engineer.
[15:26.020 --> 15:28.040] You don't have to worry about that.
[15:28.040 --> 15:32.840] And the implication, of course, a young black girl, you know, is never going to become an
[15:32.840 --> 15:33.840] engineer.
[15:33.840 --> 15:35.680] And don't forget, and also this was like in the 1940s.
[15:35.680 --> 15:40.400] So imagine, you know, the attitudes then for somebody like that becoming an engineer.
[15:40.400 --> 15:43.080] I mean, it's almost unimaginable how bad it was.
[15:43.080 --> 15:44.440] You know, today it's not great.
[15:44.440 --> 15:45.800] Back then, oof.
[15:45.800 --> 15:51.840] But Montague joined the United States Navy in 1955 in Washington, D.C.
[15:51.840 --> 15:53.560] And she was a clerk typist.
[15:53.560 --> 15:57.280] And she was sitting right next to the Univac One.
[15:57.280 --> 15:58.280] Univac One.
[15:58.280 --> 15:59.280] Univac.
[15:59.280 --> 16:00.280] Yeah.
[16:00.280 --> 16:04.520] So if you remember, the ENIAC was the first programmable, electronic, general purpose
[16:04.520 --> 16:06.080] digital computer.
[16:06.080 --> 16:09.440] There were other computers at that time that had some of those capabilities.
[16:09.440 --> 16:13.720] But that was the first one to have pretty much all of that at the same time.
[16:13.720 --> 16:16.220] And it was completed in 1945.
[16:16.220 --> 16:19.360] And it was used for the United States Army's Ballistic Research Lab.
[16:19.360 --> 16:22.480] Of course, it was an amazing tool.
[16:22.480 --> 16:24.600] Of course, it was, you know, it was a computer.
[16:24.600 --> 16:29.520] Univac One was essentially the business version of the ENIAC.
[16:29.520 --> 16:30.840] That's basically what that was.
[16:30.840 --> 16:35.240] It was the very first successful civilian computer.
[16:35.240 --> 16:39.720] And it was obviously, that was a critical piece of the dawn of the computer age.
[16:39.720 --> 16:43.720] I mean, it's a milestone of milestones right there.
[16:43.720 --> 16:45.520] And she was sitting right next to it.
[16:45.520 --> 16:46.840] She was working next to it.
[16:46.840 --> 16:50.920] And the story goes that one day, a lot, all of the engineers called in sick for whatever
[16:50.920 --> 16:51.920] reason.
[16:51.920 --> 16:53.300] I don't know if they were really partying the night before.
[16:53.300 --> 16:54.360] But none of them came in.
[16:54.360 --> 17:00.360] And she was able to dive right in and accomplish some work on the Univac One because she had
[17:00.360 --> 17:04.720] seen and she had observed the engineers using it for quite a while.
[17:04.720 --> 17:08.160] Soon after that, she was studying computer programming at night school.
[17:08.160 --> 17:11.920] And then the promotions seemed to come very, very quickly for her.
[17:11.920 --> 17:17.520] She was appointed as a computer systems analyst at the Navy Ship Engineering Center.
[17:17.520 --> 17:22.280] And then program director for the Naval Sea Systems Command Integrated Design Manufacturing
[17:22.280 --> 17:24.240] and Maintenance Program.
[17:24.240 --> 17:30.680] And then division head for the Computer Aided Design and Computer Aided Manufacturing, CAD,
[17:30.680 --> 17:37.120] CAD-CAM program, and deputy program manager of the Navy's Information Systems Improvement
[17:37.120 --> 17:38.120] Program.
[17:38.120 --> 17:40.600] So lots of titles, lots of responsibilities.
[17:40.600 --> 17:47.920] And then back in 1971, her department was challenged with a task to create a computer
[17:47.920 --> 17:52.240] generated ship design, had never really been done before.
[17:52.240 --> 17:56.640] She pulled together a lot of systems, some automated systems that had been created, pulled
[17:56.640 --> 17:57.640] them together.
[17:57.640 --> 18:06.000] And within 19 hours, she had an initial draft for an Oliver Hazard Perry class frigate.
[18:06.000 --> 18:08.960] Perry class frigate, I like the sound of that.
[18:08.960 --> 18:15.200] Within 19 hours, that made her the first person to design a ship using a computer system.
[18:15.200 --> 18:21.280] And then after that, she worked on Sea Wolf class submarines, Nimitz class aircraft carriers,
[18:21.280 --> 18:22.560] and Dwight D. Azenhower.
[18:22.560 --> 18:28.560] And just amazing to think she started as a clerk typist, and she ultimately was doing
[18:28.560 --> 18:31.720] amazing things and breaking ground.
[18:31.720 --> 18:32.720] And being the first.
[18:32.720 --> 18:33.720] What a life.
[18:33.720 --> 18:34.720] Incredible.
[18:34.720 --> 18:36.120] Being involved in all those different things, that is fantastic.
[18:36.120 --> 18:37.120] Amazing.
[18:37.120 --> 18:43.880] And also, you can imagine the pushback she got being a black woman at that time.
[18:43.880 --> 18:46.040] So I'm sure that wasn't easy as well.
[18:46.040 --> 18:51.720] Well, it's a testament to just how unbelievably talented and intelligent she was.
[18:51.720 --> 18:54.400] She had to blow people's minds in order to get there.
[18:54.400 --> 18:55.400] Absolutely.
[18:55.400 --> 19:00.480] And that's a common thread in a lot of these superhero segments that I've done, where they
[19:00.480 --> 19:06.040] were so superior that it couldn't be denied in a lot of cases.
[19:06.040 --> 19:10.720] And that's unfortunate that you have to be so amazing just to get the same opportunities
[19:10.720 --> 19:13.520] that people who are average amazing have.
[19:13.520 --> 19:14.840] All right.
[19:14.840 --> 19:20.760] So remember, the United States Navy's hidden figure, Ray Jean Montague.
[19:20.760 --> 19:24.600] Mention her to your friends, or Jay, mention her to your friend, especially when you're
[19:24.600 --> 19:25.600] discussing-
[19:25.600 --> 19:26.600] You're just Bob.
[19:26.600 --> 19:27.600] It's just me.
[19:27.600 --> 19:29.440] It's just Bob.
[19:29.440 --> 19:35.120] Especially when discussing drawing interchange formats, cattle bar arrangements, or especially
[19:35.120 --> 19:36.640] geometric modeling kernels.
[19:36.640 --> 19:37.640] Ooh, I like those.
[19:37.640 --> 19:38.640] Yes.
[19:38.640 --> 19:39.640] Thank you.

Are Fake Meats Sustainable? (19:39)
[19:39.640 --> 19:42.480] All right, Jay, tell us about the future of vat-grown meat.
[19:42.480 --> 19:45.620] This isn't the future of vat-grown meat.
[19:45.620 --> 19:50.800] It's more about the difference between plant-based meats and traditional-
[19:50.800 --> 19:51.800] And meat-based meats?
[19:51.800 --> 19:54.640] And meat-based meats that are happening today.
[19:54.640 --> 20:01.640] And the real question here when we compare the two is, how sustainable are these plant-based
[20:01.640 --> 20:03.260] meats?
[20:03.260 --> 20:05.520] What is the profile?
[20:05.520 --> 20:09.840] After doing some research and reading about it, it's pretty interesting how we got to
[20:09.840 --> 20:15.000] plant-based meats, and then we're comparing the energy and resources that it takes to
[20:15.000 --> 20:18.240] create them versus traditional meats.
[20:18.240 --> 20:23.440] So as everybody knows, a lot of people eat meat, and unfortunately, meat demand, if anything,
[20:23.440 --> 20:24.440] it's just going up.
[20:24.440 --> 20:31.640] I have to admit, the older I get, I am way more conscious now about my meat-eating usage.
[20:31.640 --> 20:33.840] I try to lower it as much as possible.
[20:33.840 --> 20:39.300] And as much as I do love meatballs and everything, I don't let myself go there.
[20:39.300 --> 20:42.640] It's like maybe once every couple of months at this point, where it was more like every
[20:42.640 --> 20:44.640] two weeks, which is a big difference for me.
[20:44.640 --> 20:46.120] Every two weeks is fine.
[20:46.120 --> 20:47.360] Yeah.
[20:47.360 --> 20:51.000] The other thing about just eating traditional meat is that it is-
[20:51.000 --> 20:52.560] Once a week is fine.
[20:52.560 --> 20:56.120] It takes a significant toll on the environment.
[20:56.120 --> 21:01.840] Traditional agriculture promotes deforestation, greenhouse gas emissions, air and water pollution.
[21:01.840 --> 21:07.560] So eating meat is just not helping global warming, which is getting worse, and everything
[21:07.560 --> 21:09.200] seems to be getting worse.
[21:09.200 --> 21:14.800] But just as I have to say, because we've covered this topic before, just to give it more nuance
[21:14.800 --> 21:20.240] to that, that doesn't mean zero meat consumption is what's optimal.
[21:20.240 --> 21:23.440] And I know this is controversial, because there are some people who think that that
[21:23.440 --> 21:29.800] is the case, but when we've done a deep dive on this topic, I think it's a fairer summary
[21:29.800 --> 21:34.400] is that we should really have a lot less meat consumption, but not zero, because there's
[21:34.400 --> 21:43.060] an integrated agricultural system where animals are good at converting non-human calories
[21:43.060 --> 21:44.900] into human calories.
[21:44.900 --> 21:48.600] So there can be an efficiency there.
[21:48.600 --> 21:53.840] And they can use land, which is not usable for growing food for people, and they can
[21:53.840 --> 21:57.460] eat food that people can eat and then convert that into food.
[21:57.460 --> 21:59.440] And they produce a lot of fertilizer.
[21:59.440 --> 22:02.440] Half of our food we grow with cattle manure.
[22:02.440 --> 22:06.840] So if they all went away, that would be a huge problem for the agricultural system.
[22:06.840 --> 22:09.160] So you're saying there's a healthy balance in there somewhere.
[22:09.160 --> 22:10.160] Yeah.
[22:10.160 --> 22:11.660] There's probably a sweet spot in there somewhere.
[22:11.660 --> 22:16.000] We're not at it right now, where I think we're just- Demand is requiring that we produce
[22:16.000 --> 22:18.160] more meat than is optimal for the system.
[22:18.160 --> 22:23.040] But not to imply that there's a consensus that we need to go to zero meat consumption.
[22:23.040 --> 22:28.660] And there's studies that show that a meat consumption at certain levels is perfectly
[22:28.660 --> 22:32.240] healthy and is not going to give you a heart attack.
[22:32.240 --> 22:36.660] So approximately 15% of global greenhouse gas emissions come from livestock.
[22:36.660 --> 22:40.460] And like I said, it's only going to go up as demand for meat goes up.
[22:40.460 --> 22:46.640] They're saying that there will be a 15% increase in meat demand in the next decade.
[22:46.640 --> 22:47.640] That is significant.
[22:47.640 --> 22:49.800] That is way more than I would have guessed.
[22:49.800 --> 22:51.840] Greenhouse gases come from where?
[22:51.840 --> 22:55.560] When you're talking about grazing animals like sheep, goats, and cows, right?
[22:55.560 --> 23:00.640] These animals burp methane that comes from them digesting grasses and the like.
[23:00.640 --> 23:04.980] So greenhouse gases also happen to come from chemicals that are used to grow feed.
[23:04.980 --> 23:09.240] So there's lots of things in the industry that are the result of these greenhouse gases.
[23:09.240 --> 23:13.800] So interestingly, chickens and pigs have much lower gas emissions than cows, which I did
[23:13.800 --> 23:14.960] not know.
[23:14.960 --> 23:17.900] They're also better at converting the calories they eat into muscle.
[23:17.900 --> 23:22.120] So for example, when we compare chickens, pigs, and cows, chickens need to eat about
[23:22.120 --> 23:26.560] two pounds of feed for each pound of edible tissue gained.
[23:26.560 --> 23:28.940] Pigs need three to five pounds of feed.
[23:28.940 --> 23:29.940] And cows need-
[23:29.940 --> 23:30.940] Per pound.
[23:30.940 --> 23:31.940] What?
[23:31.940 --> 23:32.940] Per pound.
[23:32.940 --> 23:33.940] Yeah, everything is per pound.
[23:33.940 --> 23:36.360] So a pig needs to eat three to five pounds of feed to make an edible pound.
[23:36.360 --> 23:38.960] And then cows need six to 10 pounds of feed.
[23:38.960 --> 23:39.960] Whoa.
[23:39.960 --> 23:40.960] Yeah.
[23:40.960 --> 23:41.960] So it's a really big difference here.
[23:41.960 --> 23:45.000] Pigs are even worse, they're like 15, 16.
[23:45.000 --> 23:47.000] And fish are close to one to one.
[23:47.000 --> 23:48.000] Wow.
[23:48.000 --> 23:49.000] Yeah, fish are the best.
[23:49.000 --> 23:53.600] Goats and sheep are pretty bad, but they're not consumed in as large quantities across
[23:53.600 --> 23:55.840] the globe as cows.
[23:55.840 --> 24:00.360] Just reading these stats, like eat chicken and fish, that's a good shift in your meat
[24:00.360 --> 24:01.360] right there.
[24:01.360 --> 24:02.840] Just focus on them.
[24:02.840 --> 24:09.760] Cows produce six times more gas than pigs and approximately nine times more than chickens.
[24:09.760 --> 24:14.520] So they are clearly the biggest problem when it comes to grazing animals.
[24:14.520 --> 24:17.920] So today we have products that simulate the taste of meat.
[24:17.920 --> 24:21.160] And they're completely plant-based, and I don't know if you guys have ever tried them,
[24:21.160 --> 24:22.160] but I have.
[24:22.160 --> 24:23.160] I have.
[24:23.160 --> 24:24.160] I've tried them all.
[24:24.160 --> 24:25.160] I'll tell you about it.
[24:25.160 --> 24:26.160] They taste nothing like meat.
[24:26.160 --> 24:27.160] So plant-
[24:27.160 --> 24:28.160] I love Impossible Burger.
[24:28.160 --> 24:29.160] Taste or texture?
[24:29.160 --> 24:30.160] Impossible Burger, Steve, you would not know the difference.
[24:30.160 --> 24:31.160] Oh, absolutely, I know the difference.
[24:31.160 --> 24:32.160] You've had it.
[24:32.160 --> 24:34.280] No, you know the difference, but they're the closest, I think.
[24:34.280 --> 24:35.280] If somebody gave it to-
[24:35.280 --> 24:36.280] I've had them.
[24:36.280 --> 24:38.280] If somebody gave it to me and didn't tell me, I wouldn't even realize it.
[24:38.280 --> 24:39.600] Yeah, for a hamburger, it's fine.
[24:39.600 --> 24:40.600] I mean-
[24:40.600 --> 24:41.600] It's just a little bit weirder.
[24:41.600 --> 24:42.600] That's a separate question.
[24:42.600 --> 24:44.560] I mean, they taste fine.
[24:44.560 --> 24:46.800] I would never confuse it for beef.
[24:46.800 --> 24:47.800] Right.
[24:47.800 --> 24:48.800] But they taste fine.
[24:48.800 --> 24:49.800] I think it tastes better than beef.
[24:49.800 --> 24:50.800] That's different.
[24:50.800 --> 24:51.800] Okay.
[24:51.800 --> 24:52.800] You just have a plain-
[24:52.800 --> 24:53.800] How good it is is a different question than how much-
[24:53.800 --> 24:54.800] What do you have on your hamburger?
[24:54.800 --> 24:55.800] Yeah, the whole shebang.
[24:55.800 --> 24:56.800] Yeah, pickles.
[24:56.800 --> 24:58.640] By the time you put all your condiments, you know, like how much are you, you know.
[24:58.640 --> 25:03.920] So plant-based foods create significantly lower levels of greenhouse gases than meat-based
[25:03.920 --> 25:04.920] foods.
[25:04.920 --> 25:09.080] During the 12-hour show, and this is my anecdote, last year, right, when we do that, a year
[25:09.080 --> 25:12.440] ago last spring, I cooked meatballs for everybody in real time.
[25:12.440 --> 25:18.220] And I also made Ian, because Ian is a vegetarian, I made him plant-based meatballs.
[25:18.220 --> 25:20.960] And I got to tell you, legit, they tasted good.
[25:20.960 --> 25:21.960] They were good.
[25:21.960 --> 25:22.960] They weren't-
[25:22.960 --> 25:23.960] What did you use?
[25:23.960 --> 25:26.440] You know, they weren't beef, but they were a very good flavor and the texture was fantastic.
[25:26.440 --> 25:28.440] So I wasn't really that disappointed in them.
[25:28.440 --> 25:29.680] Jay, what did you use?
[25:29.680 --> 25:31.520] I used Impossible Burger meat.
[25:31.520 --> 25:32.520] Impossible, okay.
[25:32.520 --> 25:33.520] Yeah.
[25:33.520 --> 25:38.840] I've also had Shepherd's Pie made completely out of Impossible Burger, and that was fantastic.
[25:38.840 --> 25:44.360] Because it's heavy with, you know, spices, so it obfuscates the flavor.
[25:44.360 --> 25:49.560] So the point of me saying this is you could use plant-based meats in dishes where, you
[25:49.560 --> 25:53.000] know, there's a lot of spices and everything, like for tacos and things like that.
[25:53.000 --> 25:56.820] Like, you could just think about swapping that in right away because it tastes fantastic.
[25:56.820 --> 26:01.740] So researchers were able to make a plant-based product that has similar traits as real meat
[26:01.740 --> 26:05.000] by figuring out exactly what makes meat meat.
[26:05.000 --> 26:07.020] You know, why does meat taste like meat?
[26:07.020 --> 26:08.520] Why does it have the texture that it has?
[26:08.520 --> 26:10.520] Why does it have the flavors that it has?
[26:10.520 --> 26:15.440] So as an example, many of the products that they use, like coconut oil is a great example.
[26:15.440 --> 26:20.800] They use coconut oil, I believe, in Impossible Burger because it has a similar animal fats
[26:20.800 --> 26:22.880] feel in your mouth.
[26:22.880 --> 26:25.760] Kara, it seems to me like you and I talk about heme quite a bit.
[26:25.760 --> 26:27.800] For some reason, you and I are always chit-chatting about heme.
[26:27.800 --> 26:28.800] Leg hemoglobin.
[26:28.800 --> 26:29.800] Hem!
[26:29.800 --> 26:30.800] Yeah.
[26:30.800 --> 26:31.800] Hemoglobin.
[26:31.800 --> 26:32.800] So this heme is the red liquid.
[26:32.800 --> 26:33.800] Now, this isn't blood.
[26:33.800 --> 26:40.320] It's the red liquid protein that comes out of meats if you have a steak or even ground
[26:40.320 --> 26:41.320] beef.
[26:41.320 --> 26:43.280] If you squeeze it, you see this red liquid come out.
[26:43.280 --> 26:44.280] It's blood, Jay.
[26:44.280 --> 26:45.280] By the way, it's not a red liquid.
[26:45.280 --> 26:46.280] It's not a red liquid.
[26:46.280 --> 26:47.280] It's blood.
[26:47.280 --> 26:48.280] It's not exactly blood, Steve.
[26:48.280 --> 26:49.280] It's a part of blood.
[26:49.280 --> 26:50.280] Yeah, it's a part of blood.
[26:50.280 --> 26:51.280] Watery blood.
[26:51.280 --> 26:52.720] It's a part of blood, and it's pretty amazing.
[26:52.720 --> 26:58.040] When I visited the Impossible headquarters for a TV show, I had to taste leg hemoglobin,
[26:58.040 --> 27:03.680] which is the version that they use, the plant-based version they use in Impossible Meat.
[27:03.680 --> 27:09.800] And it tastes like your mouth is full of blood, like it's gross to just eat on its own.
[27:09.800 --> 27:10.800] It makes you feel weird.
[27:10.800 --> 27:11.800] That's right.
[27:11.800 --> 27:12.800] And you're not supposed to.
[27:12.800 --> 27:16.720] But Kara, the point is, and I want to make this perfectly clear, they made a plant-based
[27:16.720 --> 27:17.720] version of heme.
[27:17.720 --> 27:19.960] Well, all plants have it.
[27:19.960 --> 27:24.800] They just were able to, first they isolated it from soy.
[27:24.800 --> 27:29.120] And then when they realized that the quantity that they could get was so tiny, they started
[27:29.120 --> 27:33.840] genetically engineering yeast to produce it, because it's just so much more efficient to
[27:33.840 --> 27:34.840] do it that way.
[27:34.840 --> 27:35.840] Yeah.
[27:35.840 --> 27:40.520] And so they cultivate these yeast, and then they create reactors that the yeast can multiply
[27:40.520 --> 27:41.520] in.
[27:41.520 --> 27:42.520] And then it cranks.
[27:42.520 --> 27:43.520] This is like insulin.
[27:43.520 --> 27:44.520] You know what I mean?
[27:44.520 --> 27:45.760] This is, by the way, is how insulin is made.
[27:45.760 --> 27:50.380] So taking a close look at how much energy is needed to produce these products will answer
[27:50.380 --> 27:55.560] the overall question that I'm putting to everybody here, is how much better is plant-based meats
[27:55.560 --> 27:57.500] for the environment than regular meat?
[27:57.500 --> 27:59.680] So let me give you guys a little bit of a background here.
[27:59.680 --> 28:03.840] So each ingredient needs to be traced back to where it comes from, from all the processes,
[28:03.840 --> 28:04.840] right?
[28:04.840 --> 28:08.480] There's a ton of processes that they need to get through in order for it to be the final
[28:08.480 --> 28:10.440] version that's found in plant-based meats.
[28:10.440 --> 28:13.420] And this is called life cycle analysis.
[28:13.420 --> 28:16.080] So for example, each ingredient is what?
[28:16.080 --> 28:20.280] They're farmed, because they're plants, they're transported, and then they're processed.
[28:20.280 --> 28:24.520] And in each of those three stages, there's a lot of things happening, and that they had
[28:24.520 --> 28:28.280] to track all of those different steps and every single thing that happens.
[28:28.280 --> 28:33.160] So each step along the way uses fuel, uses water, uses land, uses chemicals, and they
[28:33.160 --> 28:36.840] have to total up all this information for each ingredient, and that gives us the final
[28:36.840 --> 28:37.840] answer.
[28:37.840 --> 28:42.560] But the snag is, because there's always a freaking snag, is that the information wasn't
[28:42.560 --> 28:44.960] readily available to these researchers.
[28:44.960 --> 28:49.800] The companies that make plant-based meats, they're keeping their products and ingredients
[28:49.800 --> 28:54.160] and all of that information to themselves because it's proprietary.
[28:54.160 --> 28:57.560] They don't want to say, here's everything that we do and every single process that we
[28:57.560 --> 29:02.320] use because that is part of their company's business.
[29:02.320 --> 29:03.320] It does make sense.
[29:03.320 --> 29:07.160] I don't think they're doing it for malfeasance.
[29:07.160 --> 29:10.400] They're doing it because they don't want other companies to copy what they're doing.
[29:10.400 --> 29:12.120] It is their intellectual property.
[29:12.120 --> 29:17.160] So scientists had to rely on information that these companies shared about their products.
[29:17.160 --> 29:18.960] That is the one disclosure that I have here.
[29:18.960 --> 29:24.880] I'm just assuming that they gave a relatively accurate rendition of what's actually taking
[29:24.880 --> 29:25.880] place.
[29:25.880 --> 29:32.320] So to get to some numbers, Impossible Burger production only creates 11% of the greenhouse
[29:32.320 --> 29:35.400] gases produced by the same amount of beef.
[29:35.400 --> 29:36.880] That is significantly less.
[29:36.880 --> 29:38.440] Yeah, that's significant.
[29:38.440 --> 29:41.720] Other plant-based meat producers were showing similar numbers as well.
[29:41.720 --> 29:49.600] So compared to pork and chicken, pork was 37% of beef and chicken was 57%, which is
[29:49.600 --> 29:51.600] even better.
[29:51.600 --> 29:56.900] These numbers are pretty significant when you think about the impact on the environment.
[29:56.900 --> 30:02.760] Researchers also found that the amount of water used was only 23% of that in beef, 11%
[30:02.760 --> 30:05.840] used by pork and 24% in chicken for equal amounts of protein.
[30:05.840 --> 30:08.720] So they're dramatically less.
[30:08.720 --> 30:11.120] Land use has huge differences as well.
[30:11.120 --> 30:17.880] Deforested use was 2% of what beef uses for the same amount of protein, 2%, 18% for pork
[30:17.880 --> 30:20.320] and 23% for chicken.
[30:20.320 --> 30:26.240] Land use is important because, you know what, land is very important here because there
[30:26.240 --> 30:31.680] is a potential huge amount of carbon storage that an acre of land can have.
[30:31.680 --> 30:38.840] And when you're deforesting tens of thousands of acres, unfortunately, of the Amazon, you're
[30:38.840 --> 30:42.960] getting rid of an incredible amount of vegetation that's holding a lot of carbon.
[30:42.960 --> 30:43.960] So it all adds up.
[30:43.960 --> 30:48.120] But again, you know, there's always multiple angles here.
[30:48.120 --> 30:52.900] Land that cattle are grazing on is not rainforest, right?
[30:52.900 --> 30:58.820] And so a lot of that land use is not arable land or land that we could be using for agriculture.
[30:58.820 --> 31:07.040] And there is a separate movement, like another way to mitigate the resource use of cows and
[31:07.040 --> 31:20.120] meat, you know, meat-based animals, is to feed them more of the refuse, you know.
[31:20.120 --> 31:22.320] You don't grow grains to feed them.
[31:22.320 --> 31:27.200] You feed them the leftover stuff from human agriculture.
[31:27.200 --> 31:30.680] So that is more of like a circular system.
[31:30.680 --> 31:34.520] So it remains to be seen how far that can go.
[31:34.520 --> 31:37.880] But there is a huge movement in agriculture to do that.
[31:37.880 --> 31:40.440] I just read a recent news item about that.
[31:40.440 --> 31:44.440] Steve, they are clearing Amazon forest for grazing purposes.
[31:44.440 --> 31:51.120] And soybeans are also huge, very high on the list of what's being grown in former Amazon
[31:51.120 --> 31:52.720] forest right now.
[31:52.720 --> 31:54.000] So it is a problem.
[31:54.000 --> 31:56.040] And you know, they're racking back those.
[31:56.040 --> 31:57.320] That's a separate problem.
[31:57.320 --> 32:00.280] Even without animals, that's a problem.
[32:00.280 --> 32:06.160] And you know, even if they're just growing crops, whether animals are in the mix or not,
[32:06.160 --> 32:09.040] that's the worst thing they could be doing is, you know, what they're essentially doing
[32:09.040 --> 32:15.520] is burning down the forest and then planting crops to get all the nutrients out of that.
[32:15.520 --> 32:17.760] And then they move on once they...
[32:17.760 --> 32:19.600] It's not even burning down a forest.
[32:19.600 --> 32:24.000] They're like burning down libraries, essentially, I mean, because you've got genetic diversity
[32:24.000 --> 32:26.040] in those rainforests.
[32:26.040 --> 32:27.040] And they're isolated.
[32:27.040 --> 32:31.000] You have a genetic diversified area that is unique.
[32:31.000 --> 32:35.960] And once that's gone, that is gone, it's millions of years of evolution, now gone that we will
[32:35.960 --> 32:36.960] never retrieve.
[32:36.960 --> 32:40.480] There could be amazing drugs in there, amazing genetic information that is gone.
[32:40.480 --> 32:44.160] So it's so far worse than just burning down trees and stuff.
[32:44.160 --> 32:48.920] There are alternatives, like you can farm the forest, right?
[32:48.920 --> 32:55.520] You can plant and cultivate and whatever things that will grow within the forest without having
[32:55.520 --> 32:57.200] to destroy the forest itself.
[32:57.200 --> 33:00.200] Yeah, like castanhas, like Brazil nut trees, they're really sustainable.
[33:00.200 --> 33:05.560] It's a great way to harvest things that are already growing there and not disrupt the
[33:05.560 --> 33:06.560] ecosystem.
[33:06.560 --> 33:11.460] And they could also use the land they're already using for farming better by planting things
[33:11.460 --> 33:15.600] which regenerate the soil that are also cash crops, you know.
[33:15.600 --> 33:17.080] But so they're just not doing it smartly.
[33:17.080 --> 33:18.240] They're not doing it well.
[33:18.240 --> 33:22.520] Well, in some areas, people really are doing it smartly, and in other areas there's too
[33:22.520 --> 33:27.540] much demand and the cost is too high and individuals are going to do what they need to do to maintain
[33:27.540 --> 33:28.540] their livelihood.
[33:28.540 --> 33:29.540] Absolutely.
[33:29.540 --> 33:31.880] So this is way bigger than the boots on the ground in the Amazon.
[33:31.880 --> 33:36.480] It's the pressure from countries like ours asking for tropical hardwoods and asking for
[33:36.480 --> 33:41.240] more crops to be grown and more animals to be produced in those areas.
[33:41.240 --> 33:46.600] Jay, I think it's important to note because I've been looking at the comments that a lot
[33:46.600 --> 33:54.640] of these lab grown or synthetic meats that try to emulate real meat, the target audience
[33:54.640 --> 33:59.600] is not people who are already not eating meat because you hear a lot of times people going,
[33:59.600 --> 34:00.600] it grosses me out.
[34:00.600 --> 34:01.700] It tastes too much like real meat.
[34:01.700 --> 34:03.960] I don't want to eat fake meat.
[34:03.960 --> 34:04.960] It's not for you.
[34:04.960 --> 34:05.960] Yeah.
[34:05.960 --> 34:10.120] The idea that like the CEO of Impossible when I interviewed him, I think Pat Brown is his
[34:10.120 --> 34:15.360] name, he was very clear, I wanted to develop this so that I could give an alternative to
[34:15.360 --> 34:20.400] people who are doing the environmental harm, people who are eating large quantities of
[34:20.400 --> 34:21.400] meat.
[34:21.400 --> 34:22.400] Exactly.
[34:22.400 --> 34:25.720] So that they have an option to do better without giving up what they love.
[34:25.720 --> 34:32.840] So I think the meta problem here is that, yeah, there are smart agricultural practices.
[34:32.840 --> 34:35.200] There are optimal agricultural practices.
[34:35.200 --> 34:39.000] We can get the system to be more circular and work together better.
[34:39.000 --> 34:44.460] But it's not like there is a world agricultural organization that actually controls what every
[34:44.460 --> 34:46.160] farmer does.
[34:46.160 --> 34:50.500] And so what you have is individual farmers making individual decisions that are in their
[34:50.500 --> 34:52.840] best interest.
[34:52.840 --> 34:57.440] And a lot of the times it's like, well, they're making decisions so they don't starve.
[34:57.440 --> 35:01.160] They're making decisions so that they don't lose money doing what they're doing.
[35:01.160 --> 35:04.560] The margins are so razor thin with agriculture.
[35:04.560 --> 35:11.000] And so they're not necessarily doing what's optimal for the whole system, but we're at
[35:11.000 --> 35:15.720] a point with eight billion people on the planet where we're already basically using up all
[35:15.720 --> 35:20.800] the arable land and because of global warming, where we need the whole system to be efficient
[35:20.800 --> 35:22.020] together.
[35:22.020 --> 35:26.760] And that's really what we're talking about is moving towards an integrated system that's
[35:26.760 --> 35:28.640] coordinated and that's optimal.
[35:28.640 --> 35:35.340] And that may mean having to pay poor people to not do stuff or paying to give them better
[35:35.340 --> 35:38.760] ways to do things or integrating it better.
[35:38.760 --> 35:43.240] But again, individuals will make smart decisions for themselves that are not good for the whole
[35:43.240 --> 35:44.240] system.
[35:44.240 --> 35:45.240] That's really the problem.
[35:45.240 --> 35:46.240] Right.
[35:46.240 --> 35:47.240] That's why we have poaching.
[35:47.240 --> 35:49.660] That's why we have gold mining in the Amazon, because it's the only option these people
[35:49.660 --> 35:52.120] have.
[35:52.120 --> 35:56.520] I think it's fair to note here, there are some drawbacks to plant-based meats.
[35:56.520 --> 36:02.000] Right now they cost 43% more than products that they're trying to replace, which is a
[36:02.000 --> 36:03.000] lot.
[36:03.000 --> 36:06.880] And I did go on, I did some online searching and verified that that's true.
[36:06.880 --> 36:11.080] Which is another point, like if you're like a poor farmer in Africa, sometimes animal
[36:11.080 --> 36:14.580] protein is the cheapest, best protein you can get access to.
[36:14.580 --> 36:16.840] And that's very important for certain people.
[36:16.840 --> 36:21.000] Again, we can't just look at this from our perspective where like we have no issues with
[36:21.000 --> 36:24.040] getting enough food or calories or high quality proteins or stuff.
[36:24.040 --> 36:28.100] When most of the world is living on the edge, we have to be very careful about any changes
[36:28.100 --> 36:29.100] that we make.
[36:29.100 --> 36:34.680] And right now, plant-based meats are only 1% of the market, which is basically almost
[36:34.680 --> 36:35.760] nothing.
[36:35.760 --> 36:41.880] I would just like to say at this point, eat green leafy vegetables, eat beans, eat grains.
[36:41.880 --> 36:45.320] This is much healthier than predominantly eating meats.
[36:45.320 --> 36:48.920] Well, it's all about balance, but we definitely should eat more of that, and we are generally
[36:48.920 --> 36:49.920] in the West.
[36:49.920 --> 36:53.260] Well, everyone, we're going to take a quick break from our show to talk about our sponsor
[36:53.260 --> 36:54.760] this week, BetterHelp.
[36:54.760 --> 36:57.120] Yeah, and let's not sugarcoat it, everyone.
[36:57.120 --> 36:59.560] It's a tough time out there and a lot of people are struggling.
[36:59.560 --> 37:06.400] And if you are struggling and you have never decided to take the plunge and talk to somebody,
[37:06.400 --> 37:08.200] maybe now is the time.
[37:08.200 --> 37:11.640] It's so important to prioritize our mental health.
[37:11.640 --> 37:16.120] If we put that first, everything else really can follow and BetterHelp can help you with
[37:16.120 --> 37:17.120] that.
[37:17.120 --> 37:19.520] You know, I myself work as a therapist and I also go to therapy.
[37:19.520 --> 37:24.320] And I can tell you that online therapy has been really, really beneficial for a lot of
[37:24.320 --> 37:27.800] folks where it's, you know, it fits better within your day.
[37:27.800 --> 37:31.780] You have limitations to be able to get in the car and drive somewhere.
[37:31.780 --> 37:35.440] Being able to talk to somebody online can be really a lifesaver.
[37:35.440 --> 37:37.960] And it's the model that I'm now using all the time.
[37:37.960 --> 37:43.480] Yeah, Kara, you could do it on your phone or, you know, your iPad if you want to, any
[37:43.480 --> 37:45.360] way that you connect with the video.
[37:45.360 --> 37:49.400] You can even live chat with therapy sessions so you don't have to see anyone on camera
[37:49.400 --> 37:50.400] if you don't want to.
[37:50.400 --> 37:55.300] And the other great thing is you could be matched with a therapist in under 48 hours.

[38:04.480 --> 38:06.720] All right, guys, let's get back to the show.
Why Go Back to the Moon? (38:08)
Interview with The Everyday Astronaut (53:10)
Science or Fiction (1:24:55)
Theme: Past inventions that utterly failed
Item #1: In 1983, in response to the Sony Walkman craze, Audio Technica released the Sound Burger, a portable record player, complete with earbuds.[4]
Item #2: In 1981 a Swedish company marketed an all-plastic bicycle, the Itera, which turned out to be expensive to produce but failed mostly because the weak frame made it too wobbly to ride.[5]
Item #3: In the 1930s architect Buckminster Fuller designed a pre-fab house designed to be inexpensive, quick to build, and ecofriendly, made mostly out of waste cow bones from the beef industry.[6]
Item #4: In 1964, Claus Scholz of Vienna invented a phone-answering robot; however, its ability was limited to picking up and hanging up the phone.[7][8]

Skeptical Quote of the Week (1:40:32)
This job is a great scientific adventure. But it's also a great human adventure. Mankind has made giant steps forward. However, what we know is really very, very little compared to what we still have to know.
– Fabiola Gianotti, Italian experimental particle physicist
