0:00:20.313,0:00:22.184 I'm here today to challenge 0:00:22.184,0:00:26.012 the way we think[br]about food and civilization. 0:00:27.066,0:00:33.377 We live in a mobile, highly-technological,[br]largely urban civilization; 0:00:34.020,0:00:38.925 our food markets[br]are bursting with produce. 0:00:38.925,0:00:41.919 We have an amazing global system 0:00:41.919,0:00:46.862 that brings food from all over the world[br]to those who can buy it; 0:00:46.862,0:00:51.459 and there's the rub:[br]to those who can buy it. 0:00:53.180,0:00:57.322 In 2008, the food prices spiked 0:00:57.322,0:01:02.152 and food riots broke out[br]in 30 countries; governments fell. 0:01:02.996,0:01:05.780 At the time, I was working[br]as the science advisor 0:01:05.780,0:01:09.184 to the US Secretary of State,[br]then, Condoleezza Rice. 0:01:09.557,0:01:11.897 She asked me to organize 0:01:11.897,0:01:16.215 a high-level meeting[br]on this food price crisis. 0:01:16.745,0:01:22.837 Secretary of Defense Bob Gates was there;[br]he understood the implications. 0:01:24.533,0:01:27.736 In the ensuing years,[br]food prices moderated, 0:01:28.426,0:01:32.990 then spiked again,[br]and the Arab Spring began. 0:01:34.267,0:01:37.892 (Video starts) (Moderator)[br]Angry protesters burning tires, 0:01:37.892,0:01:41.588 blocking roads, and attacking[br]the police with fireworks 0:01:41.588,0:01:43.487 in the Algerian capital. 0:01:43.487,0:01:45.299 They are protesting 0:01:45.299,0:01:48.924 over the rise in food prices[br]and unemployment. 0:01:48.924,0:01:51.806 (Arabic) We do not accept[br]this government 0:01:51.806,0:01:53.789 because we've been suffering[br]for ten years 0:01:53.789,0:01:56.706 and ten more years are coming,[br]and nothing will have changed. 0:01:56.706,0:01:59.216 (Moderator) Anti riot squads 0:01:59.216,0:02:01.585 deployed in many Algerian cities 0:02:01.585,0:02:05.183 as a simmering anger[br]threatens massive protest 0:02:05.183,0:02:08.281 in the oil and gas-rich[br]North African country. 0:02:08.281,0:02:10.365 (Rioters) The government[br]is humiliating us, 0:02:10.365,0:02:12.125 they're raising the price of sugar. 0:02:12.125,0:02:13.454 We have to pay the rent, 0:02:13.454,0:02:16.607 the electricity, water,[br]sugar,and oil; we're all poor. 0:02:16.607,0:02:17.937 (Video ends) 0:02:18.657,0:02:21.270 Nina Fedoroff: You all know[br]how that came out; 0:02:21.759,0:02:25.552 and if you think[br]that's a coincidence, watch this: 0:02:27.005,0:02:30.194 the red lines mark when, 0:02:30.704,0:02:33.935 and the flags mark[br]where food riots happen - 0:02:37.309,0:02:38.713 a scary thought. 0:02:39.433,0:02:44.983 Can the stability of governments,[br]indeed civilizations, ride on food? 0:02:47.267,0:02:52.850 Let's go back for a moment[br]and look at how civilizations started. 0:02:53.766,0:02:57.929 For most of our history,[br]we were hunter-gatherers. 0:02:57.929,0:03:02.381 We spent our days [br]gathering and capturing food. 0:03:02.658,0:03:05.813 Then, about 10 or 20,000 years ago, 0:03:05.813,0:03:10.849 we began to adapt plants and animals[br]better to our own deeds, 0:03:10.849,0:03:14.668 and settle down to grow and herd them. 0:03:14.668,0:03:17.316 That, of course, is called agriculture, 0:03:17.316,0:03:20.668 and it allowed us to feed[br]more than ourselves and our families. 0:03:21.488,0:03:27.802 We could feed scribes,[br]artisans, warriors, and kings. 0:03:27.804,0:03:32.430 These are scenes [br]from a 3,000-year-old Egyptian tomb. 0:03:33.447,0:03:36.216 Cities and civilizations flourished. 0:03:36.216,0:03:42.042 What I'm saying is simply this:[br]all of human civilization emerged 0:03:42.042,0:03:46.262 because we figured out[br]how to produce surplus food. 0:03:46.262,0:03:51.812 For millennia,[br]civilizations rose and fell, 0:03:51.812,0:03:55.342 lasting largely until the land wore out 0:03:55.342,0:03:58.354 or until the neighbors invaded[br]having worn out their own. 0:04:00.757,0:04:04.866 Even at the turn of the 18th century, 0:04:07.546,0:04:09.983 Thomas Malthus told us 0:04:09.983,0:04:13.958 that we were doomed to hunger and strife 0:04:13.958,0:04:19.346 because our numbers inevitably grew faster[br]than our ability to produce food. 0:04:19.346,0:04:22.304 If Malthus thought the game was over 0:04:22.304,0:04:25.528 when we were just a billion people[br]on the face of the earth, 0:04:25.528,0:04:28.443 how did we get to today's seven billion? 0:04:29.368,0:04:32.507 It was just about the time 0:04:32.507,0:04:36.507 Malthus was penning his gloomy predictions 0:04:36.927,0:04:40.927 that science began[br]to enter agriculture in earnest. 0:04:41.752,0:04:44.089 Over the next two centuries, 0:04:44.669,0:04:50.086 three key innovations[br]transformed agriculture. 0:04:50.916,0:04:54.146 These were: synthetic fertilizer, 0:04:54.146,0:04:58.327 genetics, and the internal[br]combustion engine. 0:05:00.211,0:05:04.855 These three innovations set in motion[br]the most profound changes 0:05:04.855,0:05:08.722 in human civilization ever. 0:05:12.911,0:05:17.090 Plants do something quite extraordinary: 0:05:18.168,0:05:21.954 they make sugar out of water, in thin air; 0:05:21.954,0:05:24.670 well across the carbon dioxide in the air. 0:05:24.670,0:05:26.837 We also need nitrogen, 0:05:26.837,0:05:30.316 but most plants can't use[br]atmospheric nitrogen. 0:05:30.316,0:05:35.835 Manure contains nitrogen[br]in the right kinds of compounds, 0:05:35.835,0:05:40.458 and of course, it's been used[br]since time immemorial to fertilize crops. 0:05:41.215,0:05:45.229 The problem is there[br]isn't much nitrogen in manure 0:05:45.229,0:05:49.057 so it takes a lot of it[br]to fertilize crops, 0:05:49.057,0:05:52.949 and of course, you have to feed[br]the animals that produce the manure. 0:05:52.949,0:05:57.396 About a century ago, Fritz Haber[br]and Carl Bosch figured out 0:05:57.396,0:06:02.952 how to convert nitrogen in the atmosphere[br]to compounds plants can use. 0:06:02.952,0:06:06.741 That's done in huge plants[br]all around the world today. 0:06:08.247,0:06:09.978 And then, there's genetics. 0:06:09.978,0:06:15.539 This is Nobel laureate Norman Borlaug,[br]the father of the Green Revolution 0:06:15.539,0:06:20.221 that put the countries, the populace,[br]and famine-plagued Asian countries 0:06:20.221,0:06:22.484 on the road out of poverty. 0:06:23.055,0:06:25.143 What you might not know 0:06:25.143,0:06:29.149 is that the Green Revolution[br]was based on mutations, 0:06:29.149,0:06:35.224 genetic changes that allowed plants[br]to use fertilizer, nitrogen fertilizer, 0:06:35.224,0:06:39.434 more efficiently,[br]doubling and tripling yields. 0:06:41.468,0:06:45.972 Genetic modification, GM;[br]today, we vilify that 0:06:45.972,0:06:47.888 - I'll get back to that. 0:06:48.539,0:06:50.593 Then there's[br]the internal combustion engine: 0:06:50.593,0:06:52.815 for most of human history, 0:06:53.795,0:06:58.747 agriculture was back-breaking work[br]and occupied most people. 0:06:59.814,0:07:04.057 The populace remained largely agrarian[br]even in developed countries, 0:07:04.057,0:07:06.958 well into the 20th century. 0:07:08.928,0:07:13.520 As machines gradually took over the task, 0:07:13.520,0:07:18.600 it requires fewer and fewer people[br]to produce more and more food; 0:07:18.600,0:07:23.643 people flow to cities, cities became[br]hotbeds of innovation and collaboration; 0:07:24.897,0:07:30.732 technology-driven[br]wealth generation accelerated 0:07:30.732,0:07:35.948 giving us all the machines, the gadgets,[br]and the comforts of modern life, 0:07:35.948,0:07:38.303 even the Internet and even Twitter. 0:07:40.317,0:07:42.020 What does the future hold? 0:07:42.840,0:07:47.018 Was Malthus just plain wrong[br]because he didn't figure out science? 0:07:47.524,0:07:49.248 Are there limits 0:07:50.568,0:07:55.372 to how much, how many people[br]the plant can provision? 0:07:55.903,0:07:59.342 Will climate change help or harm? 0:07:59.342,0:08:01.003 Let's look at some trends. 0:08:01.713,0:08:04.224 Population growth is slowing, 0:08:04.224,0:08:08.961 but it's not likely to stop[br]much short of 10 billion; 0:08:08.961,0:08:10.726 probably will go higher. 0:08:13.134,0:08:17.186 As technology powers country[br]after country out of poverty, 0:08:17.186,0:08:20.694 people want to eat more meat; 0:08:20.694,0:08:27.107 transitioning from a grain-based diet[br]to a meat-based diet requires more grain; 0:08:28.469,0:08:33.273 growing more grain requires more land,[br]but there isn't any more. 0:08:34.350,0:08:37.107 In fact, we're losing it faster 0:08:37.107,0:08:41.930 to urbanization, salinization,[br]and desertification than we're adding it. 0:08:42.079,0:08:44.561 If we don't do something different, 0:08:44.561,0:08:47.109 we'll be back to Malthus in our lifetime; 0:08:47.109,0:08:53.011 well, maybe not mine,[br]but certainly yours and your children's. 0:08:55.845,0:08:58.205 Then there's climate change. 0:08:58.205,0:09:03.997 Our major food and feed crops[br]grow best at about the temperatures 0:09:03.997,0:09:06.070 that you and I find comfortable. 0:09:06.070,0:09:10.309 Let me draw your attention[br]to this very hot summer of 2003 0:09:10.309,0:09:12.207 many of you experienced it. 0:09:12.937,0:09:17.971 It was only three degrees [br]above average for the last century, 0:09:18.971,0:09:23.951 but crop yields declined by about 30%; 0:09:23.951,0:09:29.796 think about that - that's going to be[br]an average summer in a few decades, 0:09:30.666,0:09:34.266 and a cool summer[br]by the end of the century. 0:09:36.833,0:09:38.660 Then there's water - 0:09:38.660,0:09:41.989 the most productive agriculture[br]is irrigated agriculture, 0:09:41.989,0:09:45.075 and the most reliable water[br]comes from deep underground, 0:09:45.075,0:09:46.638 indeed, from fossil aquifers. 0:09:47.658,0:09:51.884 These are being exhausted faster[br]and faster the world around. 0:09:53.120,0:09:55.312 Not good trends; 0:09:56.722,0:10:03.344 I think that our past successes[br]in our bursting food markets 0:10:04.044,0:10:09.853 have led a lot of city folks into thinking[br]Malthus is ancient history; 0:10:10.743,0:10:14.260 but Norman Borlaug knew otherwise. 0:10:14.737,0:10:17.535 In his Nobel Prize speech, he said, 0:10:17.535,0:10:22.704 "We may be at high tide now,[br]but ebb tide could soon set in 0:10:22.704,0:10:26.843 if we become complacent[br]and relax our efforts," 0:10:26.843,0:10:28.766 and that's just what we've done. 0:10:29.342,0:10:34.065 We've contracted our investments[br]in agricultural research 0:10:34.065,0:10:38.687 leaving the job primarily[br]to big agribusiness companies, 0:10:38.687,0:10:41.813 and then we berated them[br]- think Monsanto. 0:10:41.813,0:10:46.525 We've taken to the notion of organic food[br]because it's more natural; 0:10:46.525,0:10:47.983 don't be seduced - 0:10:47.983,0:10:51.785 the primary tenant [br]of organic farming is a prohibition 0:10:51.785,0:10:56.368 on the use of synthetic fertilizer,[br]but manure alone can't do the job; 0:10:56.368,0:10:59.775 if we, the entire world,[br]went organic tomorrow, 0:10:59.775,0:11:03.857 we could probably feed[br]half of our current population. 0:11:05.348,0:11:08.653 So can we feed 10 billion people? 0:11:10.489,0:11:15.354 I think we can, but we have[br]to think and act differently. 0:11:17.063,0:11:22.759 Agriculture is a complex system[br]of water, energy, chemical nutrients, 0:11:22.759,0:11:25.597 environment, of course, people; 0:11:25.597,0:11:29.469 we have to optimize that system as a whole 0:11:29.469,0:11:31.767 and make it more sustainable. 0:11:31.767,0:11:34.980 Very easy to say, hard to do. 0:11:34.980,0:11:37.870 Let me give you some specifics: 0:11:37.870,0:11:40.395 we need to increase the yield 0:11:40.395,0:11:45.160 on the land we already farm[br]using less water. 0:11:45.160,0:11:50.737 One contribution of many[br]is moving high-value crops indoors. 0:11:51.078,0:11:54.714 This is a very modern greenhouse[br]in Southern California; 0:11:54.714,0:11:57.254 tomatoes are growing[br]on strings straight up 0:11:57.254,0:12:02.421 producing five to ten times as much this[br]they produce in open fields, 0:12:02.421,0:12:06.941 as much as 100 kilograms[br]per square meter per year 0:12:06.941,0:12:10.397 using a tenth as much water. 0:12:10.397,0:12:14.829 We can build greenhouses[br]in cities on rooftops, 0:12:16.626,0:12:19.123 and even in the desert[br]with a bit of tweaking, 0:12:19.892,0:12:22.450 but we won't grow our grain under glass. 0:12:23.668,0:12:26.974 Today, farmers distribute 0:12:26.974,0:12:31.200 a hundred million tons[br]of chemical fertilizer 0:12:31.200,0:12:34.195 on their fields each year. 0:12:34.195,0:12:38.263 Much of it runs off to pollute[br]our waterways, killing them; 0:12:38.263,0:12:42.291 figuring out how to deliver the nutrients[br]precisely when they are needed, 0:12:42.291,0:12:46.248 exactly where they're needed[br]is one of the challenges of the future. 0:12:46.248,0:12:48.542 Here's one system, is called fertigation, 0:12:48.542,0:12:53.164 and you can see the nutrients in the water[br]go directly to the roots underground, 0:12:53.164,0:12:55.595 but there's much more to be done. 0:12:55.595,0:12:57.664 Then there's insecticides - 0:12:57.664,0:13:02.191 we use about a billion pounds[br]a year globally, 0:13:02.191,0:13:08.549 to kill pests like this corn earworm,[br]but they also kill beneficial insects. 0:13:08.549,0:13:16.451 Rachel Carson, author of "Silent Spring"[br]that ignited the environmental movement 0:13:16.451,0:13:17.758 dreamed of a time 0:13:17.758,0:13:21.964 that we could do this biologically[br]rather than with toxic chemicals. 0:13:21.964,0:13:26.399 Now we can: take this corn[br]- is called BT corn. 0:13:26.399,0:13:30.061 similar to any other corn[br]except it has one extra gene in it, 0:13:30.061,0:13:35.480 taken from a safe bacterium [br]used as a pesticide by organic farmers 0:13:35.480,0:13:39.486 and put directly[br]into the genome of the plant. 0:13:40.083,0:13:44.093 This is modern genetic modification, GM: 0:13:44.093,0:13:47.805 the plant produces the bacterial protein, 0:13:47.805,0:13:53.513 and it affects only the insects[br]that munch on the plant; 0:13:53.513,0:13:57.654 insecticide use has gone down[br]a lot, worldwide, 0:13:57.654,0:14:01.527 with the use of these plants,[br]with these crops, 0:14:03.477,0:14:07.055 beneficial insects flourish,[br]and farmers' prices come down; 0:14:07.055,0:14:09.868 but there's much, much more[br]that can be done. 0:14:09.868,0:14:13.982 We can look forward to crops[br]that withstand drought, 0:14:13.982,0:14:18.674 that use nitrogen more efficiently,[br]that tolerate heat, 0:14:18.674,0:14:22.597 and they are frankly,[br]more nutritious for us, 0:14:23.857,0:14:31.065 but contemporary[br]genetically modified crops 0:14:31.945,0:14:35.452 are the only ones[br]that have gotten the GMO moniker, 0:14:35.452,0:14:37.038 and that's a fearful word. 0:14:37.038,0:14:40.425 Google it, and you'll be astounded: 0:14:40.865,0:14:44.572 GMOs have been blamed[br]for farmer suicides in India, 0:14:44.572,0:14:49.313 tumors in rats,[br]and every manner of human ill 0:14:49.313,0:14:53.797 from autism to obesity[br]to infertility and cancer. 0:14:55.883,0:15:00.789 Scary - fortunately, none of it is true. 0:15:02.677,0:15:07.333 Indeed, after 25 years[br]of government research, 0:15:07.333,0:15:14.934 the EU published a report, basically[br]summarizing the 25 years of research 0:15:14.934,0:15:18.171 costing upwards of 300 million euros 0:15:18.171,0:15:24.549 by saying very simply the modification[br]of plants by GM techniques 0:15:24.549,0:15:29.619 is no more dangerous than modification[br]of plants by other techniques. 0:15:31.369,0:15:39.615 But the GMO wars rage on[br]fueled by electronic gossip, 0:15:39.615,0:15:44.421 by organizations[br]that exploit GM fears for profit;
