0:00:00.761,0:00:03.991 Imagine you are a part 0:00:03.991,0:00:06.124 of a crew of astronauts 0:00:06.124,0:00:10.067 traveling to Mars or some distant planet. 0:00:10.067,0:00:13.124 The travel time could take a year, 0:00:13.124,0:00:14.987 or even longer. 0:00:14.987,0:00:17.924 The space on board and the resources 0:00:17.924,0:00:19.712 would be limited. 0:00:19.712,0:00:24.012 So you and the crew would have[br]to figure out how to produce food 0:00:24.012,0:00:25.877 with minimal inputs. 0:00:25.877,0:00:28.276 What if you could bring with you 0:00:28.276,0:00:30.368 just a few packets of seeds, 0:00:30.368,0:00:35.113 and grow crops in a matter of hours, 0:00:35.113,0:00:38.573 and what if those crops would then[br]make more seeds, 0:00:38.573,0:00:41.381 enabling you to feed the entire crew 0:00:41.381,0:00:46.245 with just those few packets of seeds[br]for the duration of the trip? 0:00:46.245,0:00:50.775 Well, the scientists at NASA actually[br]figured out a way to do this. 0:00:50.775,0:00:53.747 What they came up with[br]was actually quite interesting, 0:00:53.747,0:00:56.253 and it involved microorganisms, 0:00:56.253,0:00:59.010 which are single-celled organisms. 0:00:59.010,0:01:01.726 And they also used hydrogen from water. 0:01:01.726,0:01:05.374 The types of microbes that they used[br]were called hydrogenotropes, 0:01:05.374,0:01:10.845 and with these hydrogenotropes,[br]you can create a virtuous carbon cycle 0:01:10.845,0:01:14.185 that would sustain life[br]on board a spacecraft. 0:01:14.185,0:01:18.370 Astronauts would breathe out[br]carbon dioxide. 0:01:18.370,0:01:22.162 That carbon dioxide would then[br]be captured by the microbes 0:01:22.162,0:01:26.168 and converted into a nutritious,[br]carbon-rich crop. 0:01:26.168,0:01:29.953 The astronauts would then eat[br]that carbon-rich crop, 0:01:29.953,0:01:33.916 and exhale the carbon out[br]in the form of carbon dioxide, 0:01:33.916,0:01:36.226 which would then be captured[br]by the microbes 0:01:36.226,0:01:37.823 to create a nutritious crop, 0:01:37.823,0:01:40.913 which then would be exhaled[br]in the form of carbon dioxide 0:01:40.913,0:01:42.176 by the astronauts. 0:01:42.176,0:01:46.034 So in this way, a closed loop[br]carbon cycle is created. 0:01:46.034,0:01:48.344 So why is this important? 0:01:48.344,0:01:50.941 We need carbon to survive as humans, 0:01:50.941,0:01:53.172 and we get our carbon from food. 0:01:53.172,0:01:55.093 On a long space journey, 0:01:55.093,0:01:58.380 you simply wouldn't be able to pick up[br]any carbon along the way, 0:01:58.380,0:02:01.982 so you'd have to figure out[br]how to recycle it on board. 0:02:01.982,0:02:04.714 This is a clever solution, right? 0:02:04.714,0:02:08.739 But the thing is, that research[br]didn't really go anywhere. 0:02:08.739,0:02:12.419 We haven't yet gone to Mars.[br]We haven't yet gone to another planet. 0:02:12.419,0:02:15.245 And this was actually done[br]in the '60s and '70s. 0:02:15.245,0:02:18.629 So a colleague of mine,[br]Dr. John Reed, and I, 0:02:18.629,0:02:22.985 we were interested actually[br]in carbon recycling here on Earth. 0:02:22.985,0:02:24.996 We wanted to come up[br]with technical solutions 0:02:24.996,0:02:26.870 to address climate change. 0:02:26.870,0:02:28.862 And we discovered this research 0:02:28.862,0:02:34.696 by reading some papers published[br]in the '60s, 1967 and later articles 0:02:34.696,0:02:36.459 about this work, 0:02:36.459,0:02:38.946 and we thought it was a really good idea. 0:02:38.946,0:02:42.299 And so we said, well,[br]Earth is actually like a spaceship. 0:02:42.299,0:02:44.206 We have limited space 0:02:44.206,0:02:45.988 and limited resources, 0:02:45.988,0:02:48.861 and on Earth we really do need[br]to figure out how to recycle 0:02:48.861,0:02:50.660 our carbon better. 0:02:50.660,0:02:53.373 So we had the idea, 0:02:53.373,0:02:57.535 can we take some of these NASA-type ideas 0:02:57.535,0:03:01.622 and apply them to our carbon problem 0:03:01.622,0:03:02.936 here on Earth? 0:03:02.936,0:03:05.592 Could we cultivate[br]these NASA-type microbes 0:03:05.592,0:03:08.562 in order to make valuable products[br]here on Earth. 0:03:08.562,0:03:11.149 And we started a company to do it, 0:03:11.149,0:03:13.280 and in that company, 0:03:13.280,0:03:16.421 we actually discovered that these[br]hydrogenotropes, 0:03:16.421,0:03:20.382 which I'll actually call nature's[br]supercharged carbon recyclers, 0:03:20.382,0:03:23.225 we found that they are[br]a powerful class of microbes 0:03:23.225,0:03:27.077 that had been largely overlooked[br]and understudied, 0:03:27.077,0:03:30.210 and that they could make[br]some really valuable products. 0:03:30.210,0:03:35.355 And so we began cultivating[br]these products, these microbes in our lab. 0:03:35.355,0:03:37.754 We found that we can make[br]essential amino acids 0:03:37.754,0:03:39.466 from carbon dioxide using these microbes, 0:03:39.466,0:03:43.484 and we even made a protein-rich meal 0:03:43.484,0:03:46.224 that has an amino acid profile 0:03:46.224,0:03:50.607 that's similar to what you might find[br]in some animal proteins. 0:03:50.607,0:03:52.957 And we began cultivating[br]them even further, 0:03:52.957,0:03:55.121 and we found that we can make oil. 0:03:55.121,0:03:57.548 And oils are used to manufacture[br]many products. 0:03:57.548,0:04:00.986 We made an oil that was similar[br]to a citrus oil, 0:04:00.986,0:04:04.111 which can be used for flavoring[br]and for fragrances, 0:04:04.111,0:04:06.668 but it also can be used[br]as a biodegradable cleaner 0:04:06.668,0:04:09.121 or even as a jet fuel. 0:04:09.121,0:04:12.065 And we made an oil[br]that's similar to palm oil. 0:04:12.065,0:04:16.191 And palm oil is used to manufacture[br]a wide range of consumer 0:04:16.191,0:04:18.715 and industrial goods. 0:04:18.715,0:04:21.460 So we began working with manufacturers 0:04:21.460,0:04:23.763 to scale up this technology, 0:04:23.763,0:04:27.236 and we are currently working with them[br]to bring some of these products to market. 0:04:28.836,0:04:31.928 We believe that this type of technology[br]can indeed help us 0:04:31.928,0:04:35.484 profitably recycle carbon dioxide[br]into valuable products, 0:04:35.484,0:04:38.023 something that's beneficial for the planet 0:04:38.023,0:04:40.354 but also beneficial for business. 0:04:40.354,0:04:42.427 But that's what we're doing today, 0:04:42.427,0:04:46.372 but tomorrow, this type of technology[br]and using these types of microbes 0:04:46.372,0:04:49.465 actually could help us[br]do something even greater, 0:04:49.465,0:04:52.260 if we take it to the next level. 0:04:52.260,0:04:54.586 So we believe that this type of technology 0:04:54.586,0:04:57.958 can actually help us address[br]an issue with agriculture, 0:04:57.958,0:05:02.434 and allow us to create[br]a type of agriculture that's sustainable, 0:05:02.434,0:05:06.719 that will allow us to scale[br]to meet the demands of tomorrow. 0:05:06.719,0:05:10.089 And why might we need[br]a sustainable agriculture? 0:05:10.089,0:05:15.328 Well actually, it is estimated[br]that the population will reach 0:05:15.328,0:05:18.074 about 10 billion by 2050, 0:05:18.074,0:05:21.138 and we're projecting that we will need[br]to increase food production 0:05:21.138,0:05:23.373 by 70 percent. 0:05:23.373,0:05:26.634 In addition, we will need many more[br]resources and raw materials 0:05:26.634,0:05:29.628 to make consumer goods[br]and industrial goods. 0:05:29.628,0:05:32.765 So how will we scale to meet that demand? 0:05:32.765,0:05:38.903 Well, modern agriculture simply cannot[br]sustainably scale to meet that demand, 0:05:38.903,0:05:41.145 and there are a number of reasons why, 0:05:41.145,0:05:46.028 and one of them is that modern agriculture[br]is one of the largest emitters 0:05:46.028,0:05:48.064 of greenhouse gases. 0:05:48.064,0:05:51.330 In fact, it emits more greenhouse gases 0:05:51.330,0:05:54.700 than our cars, our trucks, our planes, 0:05:54.700,0:05:57.283 and our trains combined. 0:05:57.283,0:05:59.717 Another reason is that modern ag 0:05:59.717,0:06:02.621 simply takes up a whole lot of land. 0:06:02.621,0:06:06.621 We have cleared 19.4 million square miles 0:06:06.621,0:06:09.240 for crops and for livestock. 0:06:09.240,0:06:11.118 What does that look like? 0:06:11.118,0:06:16.693 Well, that's roughly the size[br]of South America and Africa combined. 0:06:16.693,0:06:19.124 And let me give you a specific example. 0:06:19.124,0:06:23.437 In Indonesia, an amount[br]of virgin rainforest 0:06:23.437,0:06:27.962 was cleared totaling the size[br]of approximately Ireland 0:06:27.962,0:06:30.966 between 2000 and 2012. 0:06:30.966,0:06:33.006 Just think of all of the species, 0:06:33.006,0:06:35.861 the diversity, that was removed[br]in the process, 0:06:35.861,0:06:39.145 whether plant life, insects,[br]or animal life. 0:06:39.145,0:06:42.954 And a natural carbon sink[br]was also removed. 0:06:42.954,0:06:44.896 And so let me make this real for you. 0:06:44.896,0:06:49.516 This clearing happened primarily[br]to make room for palm plantations. 0:06:49.516,0:06:51.017 And as I mentioned before, 0:06:51.017,0:06:52.606 palm oil is used 0:06:52.606,0:06:54.522 to manufacture many products. 0:06:54.522,0:06:58.117 In fact, it is estimated[br]that over 50 percent of consumer products 0:06:58.117,0:07:01.671 are manufactured using palm oil. 0:07:01.671,0:07:04.086 And that includes things like ice cream, 0:07:04.086,0:07:05.619 cookies. 0:07:05.619,0:07:07.476 It includes cooking oils. 0:07:07.476,0:07:11.682 It also includes detergents,[br]lotions, soaps. 0:07:11.682,0:07:13.451 So you and I both 0:07:13.451,0:07:15.970 probably have numerous items 0:07:15.970,0:07:19.013 in our kitchens and our bathrooms 0:07:19.013,0:07:21.498 that were manufactured using palm oil. 0:07:21.498,0:07:27.797 So you and I are direct beneficiaries[br]of removed rainforest. 0:07:27.797,0:07:30.015 So modern ag has some problems, 0:07:30.015,0:07:34.529 and we need solutions[br]if we want to scale sustainably. 0:07:34.529,0:07:39.701 So I believe that microbes[br]can be a part of the answer, 0:07:39.701,0:07:43.965 and specifically these super-charged[br]carbon recyclers. 0:07:43.965,0:07:46.329 These super-charged carbon recyclers, 0:07:46.329,0:07:50.309 like plants, serve as[br]the natural recyclers 0:07:50.309,0:07:52.563 in their ecosystems where they thrive, 0:07:52.563,0:07:54.866 and they thrive in exotic places on Earth 0:07:54.866,0:07:57.394 like hydrothermal vents and hot springs. 0:07:57.394,0:08:00.993 And in those ecosystems,[br]they take carbon and they recycle it 0:08:00.993,0:08:03.784 into the nutrients needed[br]for those ecosystems. 0:08:03.784,0:08:05.519 And they're rich in nutrients, 0:08:05.519,0:08:08.545 such as oils and proteins, minerals 0:08:08.545,0:08:12.166 and carbohydrates. 0:08:12.166,0:08:17.544 And actually, microbes are already[br]an integral part of our everyday lives. 0:08:17.544,0:08:20.724 So if you enjoy a glass of pinot noir 0:08:20.724,0:08:23.534 on a Friday night[br]after a long, hard work week, 0:08:23.534,0:08:26.747 then you are enjoying[br]a product of microbes. 0:08:26.747,0:08:29.618 If you enjoy a beer[br]from your local microbrewery, 0:08:29.618,0:08:31.738 a product of microbes. 0:08:31.738,0:08:35.219 Or bread, or cheese, or yogurt. 0:08:35.219,0:08:37.954 These are all products of microbes. 0:08:37.954,0:08:41.494 But the beauty and the power[br]associated with these super-charged 0:08:41.494,0:08:43.249 carbon recyclers 0:08:43.249,0:08:48.162 lies in the fact that they can actually[br]produce in a matter of hours 0:08:48.162,0:08:49.656 versus months, 0:08:49.656,0:08:51.553 so that means we can make crops 0:08:51.553,0:08:55.078 much faster than we're making them today. 0:08:55.078,0:08:57.273 They grow in the dark, 0:08:57.273,0:08:59.609 so they can grow in any season 0:08:59.609,0:09:03.066 and in any geography and any location. 0:09:03.066,0:09:07.777 And they can grow in containers[br]that require minimal space. 0:09:07.777,0:09:11.693 And we can get to a type[br]of vertical agriculture, 0:09:11.693,0:09:14.548 instead of our traditional[br]horizontal agriculture 0:09:14.548,0:09:16.027 that requires so much land. 0:09:16.027,0:09:17.600 We can scale vertically, 0:09:17.600,0:09:21.502 and as a result produce much more product 0:09:21.502,0:09:24.323 per area. 0:09:24.323,0:09:28.486 If we implement this type of approach[br]and use these carbon recyclers, 0:09:28.486,0:09:31.995 then we wouldn't have to remove[br]any more rainforests 0:09:31.995,0:09:35.993 to make the food and the goods[br]that we consume. 0:09:35.993,0:09:38.838 Because, at a large scale, 0:09:38.838,0:09:40.238 you can actually make 0:09:40.238,0:09:43.956 10,000 time more output per land area 0:09:43.956,0:09:47.272 than you could, for instance,[br]if you used soybeans, 0:09:47.272,0:09:50.100 if you planted soybeans[br]on that same are of land 0:09:50.100,0:09:52.531 over a period of a year. 0:09:52.531,0:09:56.125 Ten thousand times[br]over a period of a year. 0:09:56.125,0:09:58.024 So this is what I mean 0:09:58.024,0:09:59.994 by a new type of agriculture, 0:09:59.994,0:10:02.300 and this is what I mean 0:10:02.300,0:10:03.945 by developing a system 0:10:03.945,0:10:06.245 that allows us to sustainably scale 0:10:06.245,0:10:09.884 to meet the demands of 10 billion. 0:10:09.884,0:10:12.175 And what would be the products 0:10:12.175,0:10:14.512 of this new type of agriculture? 0:10:14.512,0:10:16.530 Well, we've already made a protein meal, 0:10:16.530,0:10:19.970 so you can imagine something[br]similar to a soybean meal, 0:10:19.970,0:10:22.409 or even cornmeal, or wheat flour. 0:10:22.409,0:10:23.785 We've already made oils, 0:10:23.785,0:10:29.818 so you can imagine something similar to[br]coconut oil or olive oil or soybean oil. 0:10:29.818,0:10:32.084 So this type of crop 0:10:32.084,0:10:34.304 can actually produce the nutrients 0:10:34.304,0:10:36.490 that would give us pasta and bread, 0:10:36.490,0:10:40.306 cakes, nutritional items of many sorts. 0:10:40.306,0:10:43.379 And furthermore, since oil 0:10:43.379,0:10:47.327 is actually used to manufacture[br]multiple other goods, 0:10:47.327,0:10:49.343 industrial products,[br]and consumer products, 0:10:49.343,0:10:54.237 you can imagine being able to make[br]detergents, soaps, lotions, etc. 0:10:54.237,0:10:56.706 using these types of crops. 0:10:56.706,0:10:59.988 So not only are we running out space, 0:10:59.988,0:11:03.650 but if we continue to operate[br]under the status quo 0:11:03.650,0:11:05.052 with modern agriculture, 0:11:05.052,0:11:07.804 we run the risk of robbing our progeny 0:11:07.804,0:11:10.375 of a beautiful planet. 0:11:10.375,0:11:12.532 But it doesn't have to be this way. 0:11:12.532,0:11:15.334 We can imagine a future of abundance. 0:11:15.334,0:11:22.214 Let us create systems that[br]keep planet Earth, our spaceship, 0:11:22.214,0:11:24.317 not only from not crashing, 0:11:24.317,0:11:28.458 but let us also develop systems[br]and ways of living 0:11:28.458,0:11:32.639 that will be beneficial[br]to the lives of ourselves 0:11:32.639,0:11:36.635 and the 10 billion that will be[br]on this planet by 2050. 0:11:36.635,0:11:38.489 Thank you very much. 0:11:38.489,0:11:42.079 (Applause)
