Synopsis
Our food systems have not been designed to adapt to major disruptions like climate change, says environmental journalist Amanda Little. In this eye-opening talk, she shows how the climate crisis could devastate our food supply -- and introduces us to the farmers, entrepreneurs and engineers who are radically rethinking what we grow and how we eat, combining traditional agriculture with state-of-the-art technology to create a robust, resilient and sustainable food future.
1 | 00:12 | In the early months of the pandemic, | ||
2 | 00:14 | chef José Andrés circulated two photos | ||
3 | 00:17 | that have come to symbolize a modern American food crisis. | ||
4 | 00:21 | The first shows mountains of potatoes | ||
5 | 00:23 | that have been left to rot in a field in Idaho. | ||
6 | 00:25 | The restaurants and cafeterias and stadiums that had consumed them | ||
7 | 00:29 | were shuttered during the pandemic. | ||
8 | 00:32 | The second shows a devastating scene outside of the San Antonio food bank. | ||
9 | 00:36 | Thousands of carloads of people lined up, | ||
10 | 00:39 | waiting for food with not enough supply to go around. | ||
11 | 00:42 | "How is it possible these two photos exist at the same time, | ||
12 | 00:46 | in the most prosperous | ||
13 | 00:48 | and technologically advanced moment in our history," tweeted Andrés. | ||
14 | 00:52 | In the months after the photos were published, | ||
15 | 00:55 | the crisis got worse. | ||
16 | 00:58 | Billions of pounds of potatoes and other fresh produce | ||
17 | 01:01 | were chucked by American farmers. | ||
18 | 01:03 | At the same time, | ||
19 | 01:05 | food banks all over the country were reporting demand increases | ||
20 | 01:08 | and 40 percent were facing critical shortfalls. | ||
21 | 01:11 | Outside the US, | ||
22 | 01:13 | especially in the Middle East and throughout Southeastern Africa, | ||
23 | 01:17 | COVID-19 was paralyzing food systems that were already vulnerable. | ||
24 | 01:21 | Oxfam has predicted that by the end of 2020 | ||
25 | 01:25 | 12,000 people per day could die of hunger related to COVID. | ||
26 | 01:30 | That's more than the highest daily mortality rate | ||
27 | 01:33 | recorded so far. | ||
28 | 01:35 | But what's worse | ||
29 | 01:36 | and what's much more concerning to all of us | ||
30 | 01:38 | is that COVID is just one of many major disruptions | ||
31 | 01:42 | that have been predicted | ||
32 | 01:43 | in the years and decades ahead. | ||
33 | 01:46 | More chronic and complex than the pressures of COVID | ||
34 | 01:50 | are the pressures of climate change. | ||
35 | 01:52 | And those of you who live in California have seen this on your farms. | ||
36 | 01:56 | You've seen withering heat and drought and fires | ||
37 | 02:00 | disrupt avocado and almond and citrus and strawberry farms. | ||
38 | 02:06 | This summer, we saw the devastating impacts of storms | ||
39 | 02:09 | on corn and soy farms. | ||
40 | 02:11 | I've seen the various pressures of drought, | ||
41 | 02:14 | heat, flooding, superstorms, | ||
42 | 02:17 | invasive insects, bacterial blight, | ||
43 | 02:19 | shifting seasons and weather volatility | ||
44 | 02:22 | from Washington to Florida, | ||
45 | 02:24 | and from Guatemala to Australia. | ||
46 | 02:27 | The upshot is this. | ||
47 | 02:29 | Climate change is becoming something we can taste. | ||
48 | 02:31 | This is a kitchen-table issue in the literal sense. | ||
49 | 02:35 | The International Panel on Climate Change | ||
50 | 02:37 | has predicted that by mid-century | ||
51 | 02:39 | the world may reach a threshold of global warming | ||
52 | 02:42 | beyond which current agricultural practices | ||
53 | 02:45 | can no longer support large human civilizations. | ||
54 | 02:49 | The USDA scientist Jerry Hatfield put it to me this way: | ||
55 | 02:53 | the single biggest threat of climate change | ||
56 | 02:55 | is the collapse of food systems. | ||
57 | 02:58 | The reality we face, | ||
58 | 03:00 | one that was exposed by those mountains of potatoes | ||
59 | 03:02 | and the cars lined up during the pandemic, | ||
60 | 03:05 | is that our supply chains are antiquated. | ||
61 | 03:09 | Our food systems have not been designed | ||
62 | 03:11 | to adapt to major disruptions or preempt them. | ||
63 | 03:16 | Addressing this challenge as much as any other | ||
64 | 03:19 | is going to define our progress in the coming century. | ||
65 | 03:23 | But there's good news. | ||
66 | 03:25 | And the good news is that farmers and entrepreneurs and academics | ||
67 | 03:29 | are radically rethinking national and global food systems. | ||
68 | 03:33 | They are marrying principles of old-world agroecology | ||
69 | 03:36 | and state-of-the-art technologies | ||
70 | 03:38 | to create what I call a third way to our food future. | ||
71 | 03:43 | We're going to see radical changes | ||
72 | 03:44 | in what we grow and how we eat in the coming decades, | ||
73 | 03:48 | as these environmental and population | ||
74 | 03:50 | and public health pressures intensify. | ||
75 | 03:53 | I studied these changes for my book "The Fate of Food: | ||
76 | 03:55 | What We'll Eat in a Bigger, Hotter, Smarter World." | ||
77 | 03:58 | I traveled for five years into the lands and the minds | ||
78 | 04:01 | and the machines that are shaping the future of food. | ||
79 | 04:04 | My travels took me through 15 countries and 18 states, | ||
80 | 04:09 | from apple orchards in Wisconsin to tiny cornfields in Kenya, | ||
81 | 04:14 | to massive Norwegian fish farms | ||
82 | 04:16 | and computerized foodscapes in Shanghai. | ||
83 | 04:19 | I investigated new ideas, | ||
84 | 04:20 | like robotics and CRISPR and vertical farms. | ||
85 | 04:24 | And old ideas, like edible insects and permaculture and ancient plants. | ||
86 | 04:29 | I began to see the emergence of this third way to food production. | ||
87 | 04:33 | A synthesis of the traditional and the radically new. | ||
88 | 04:38 | There's a growing controversy | ||
89 | 04:40 | about the best path to future food security in the US. | ||
90 | 04:43 | Food is ripe for reinvention, Bill Gates has proclaimed. | ||
91 | 04:47 | Huge flows of investment | ||
92 | 04:49 | are funding new methods of climate-smart and high-tech agriculture. | ||
93 | 04:54 | But many sustainable food advocates bristle at this idea of reinvention. | ||
94 | 04:58 | They want food deinvented. | ||
95 | 05:00 | They argue for a return to preindustrial | ||
96 | 05:04 | and pre-green revolution, | ||
97 | 05:06 | biodynamic and organic farming. | ||
98 | 05:09 | To which skeptics inevitably respond, | ||
99 | 05:11 | "Nice, but does it scale? | ||
100 | 05:13 | Sure, a return to traditional farming methods | ||
101 | 05:16 | could produce better food, | ||
102 | 05:17 | but can it produce enough food that's affordable?" | ||
103 | 05:20 | The rift between the reinvention camp and the deinvention camp | ||
104 | 05:23 | has existed for decades. | ||
105 | 05:25 | But now it's a raging battle. | ||
106 | 05:29 | One side covets the past, | ||
107 | 05:30 | the other side covets the future | ||
108 | 05:32 | and as someone observing this from the outside, | ||
109 | 05:35 | I began to wonder, why must it be so binary? | ||
110 | 05:38 | Can't there be a synthesis of the two approaches? | ||
111 | 05:41 | Our challenge is to borrow from the wisdom of the ages, | ||
112 | 05:45 | and from our most advanced science, | ||
113 | 05:48 | to forge this third way. | ||
114 | 05:51 | One that allows us to improve and scale our harvests, | ||
115 | 05:54 | while restoring rather than degrading | ||
116 | 05:56 | the underlying web of life. | ||
117 | 05:59 | I belong to neither camp. | ||
118 | 06:02 | I'm a failed vegan and a lapsed vegetarian, | ||
119 | 06:04 | and a terrible backyard farmer. | ||
120 | 06:06 | If I'm honest, | ||
121 | 06:08 | I will keep trying at this, but I may fail. | ||
122 | 06:11 | But I'm hell-bent on hope, | ||
123 | 06:13 | and if my travels have taught me anything, | ||
124 | 06:15 | it's that there's good reason for hope. | ||
125 | 06:18 | Plenty of solutions are merging | ||
126 | 06:19 | that can help build sustainable, resilient food systems. | ||
127 | 06:22 | Even if we can't rely on a critical mass | ||
128 | 06:24 | of backyard-farming vegetarians to do this on their own, | ||
129 | 06:28 | from the ground up. | ||
130 | 06:30 | Let's start with artificial intelligence and robotics. | ||
131 | 06:33 | Jorge Heraud is a Peruvian-born engineer | ||
132 | 06:36 | who now lives in Silicon Valley, | ||
133 | 06:38 | and his company developed a robotic weeder named See and Spray, | ||
134 | 06:42 | and I went to Arkansas to see the maiden voyage of See and Spray. | ||
135 | 06:47 | And I was half expecting a battalion of C3PO-style robots | ||
136 | 06:51 | to march into the fields with pincer hands to pluck the weeds. | ||
137 | 06:55 | And instead, I found this. | ||
138 | 06:56 | A tractor with a big, white hoop skirt off the back of it. | ||
139 | 07:00 | And inside that hoop skirt are 24 cameras | ||
140 | 07:02 | that use computer vision to see the ground beneath | ||
141 | 07:06 | and to distinguish between the plants and the weeds. | ||
142 | 07:09 | And to deploy with sniper-like precision | ||
143 | 07:11 | these tiny jets of concentrated fertilizer, | ||
144 | 07:14 | or herbicide, | ||
145 | 07:16 | that incinerate the baby weeds. | ||
146 | 07:18 | I learned how robotics can end the practice | ||
147 | 07:21 | of broadcast spraying chemicals across millions of acres of land | ||
148 | 07:25 | and how we can reduce the use of herbicides | ||
149 | 07:28 | by up to 90 percent. | ||
150 | 07:30 | But the bigger picture is even more exciting. | ||
151 | 07:33 | Intelligent machines can treat plants individually, | ||
152 | 07:36 | applying not just herbicides | ||
153 | 07:37 | but fungicides and insecticides | ||
154 | 07:39 | and fertilizers on a plant-by-plant, rather than field-by-field basis. | ||
155 | 07:45 | So that eventually, | ||
156 | 07:46 | this kind of hyperspecific farming | ||
157 | 07:49 | can allow for more diversity and intercropping on fields. | ||
158 | 07:53 | And big farms can begin to mimic natural systems | ||
159 | 07:57 | and improve soil health. | ||
160 | 07:59 | Heraud is the embodiment of third-way thinking, right? | ||
161 | 08:03 | Robots, he told me, | ||
162 | 08:05 | don't have to remove us from nature, | ||
163 | 08:07 | they can bring us closer to it, they can restore it. | ||
164 | 08:10 | Increasing crop diversity will be crucial | ||
165 | 08:13 | to building resilient food systems. | ||
166 | 08:16 | And so will decentralizing agriculture | ||
167 | 08:19 | so that when farmers in one region are disrupted, | ||
168 | 08:21 | the others around, they can keep growing. | ||
169 | 08:23 | The rise of vertical farms, | ||
170 | 08:25 | like this farm, built inside a former steel mill in Newark, New Jersey, | ||
171 | 08:31 | can play a key role in decentralizing agriculture. | ||
172 | 08:35 | Aeroponic farms use a tiny fraction | ||
173 | 08:37 | of the water that is used in in-ground farms. | ||
174 | 08:41 | And they can grow food much faster, about 40 percent faster. | ||
175 | 08:45 | And when located in and near cities, | ||
176 | 08:47 | where the food is consumed, | ||
177 | 08:48 | they eliminate a huge amount of trucking and food waste. | ||
178 | 08:52 | It struck me at first as creepy | ||
179 | 08:54 | in kind of a "Silent Running" way | ||
180 | 08:56 | that we'd be growing our future fruits and vegetables | ||
181 | 08:59 | inside, without soil or sun. | ||
182 | 09:03 | And after weeks of spending time in these plant factories, | ||
183 | 09:06 | I began to see it as oddly, almost perfectly natural | ||
184 | 09:10 | to deliver the plants only and exactly what they need, | ||
185 | 09:13 | with zero herbicides and radical efficiency. | ||
186 | 09:16 | Here again, we see innovators borrowing from, | ||
187 | 09:19 | and perhaps even elevating the wisdom of natural ecosystems. | ||
188 | 09:24 | Developments in plant-based and alternative meats | ||
189 | 09:27 | are also profoundly hopeful. | ||
190 | 09:29 | And they follow a similar trend | ||
191 | 09:31 | toward local, resilient, low-carbon protein production. | ||
192 | 09:36 | Consumers are excited about this, | ||
193 | 09:38 | and during the pandemic, | ||
194 | 09:39 | we've seen a 250 percent increase | ||
195 | 09:41 | in demand for alternative meats. | ||
196 | 09:44 | A study by the Journal of Clinical Nutrition | ||
197 | 09:46 | found that the participants who were eating the plant-based proteins | ||
198 | 09:52 | saw a drop in their cholesterol levels, | ||
199 | 09:55 | in their weight | ||
200 | 09:56 | and eventually, a drop in their risk of heart disease. | ||
201 | 10:00 | The potential environmental benefits of plant-based meats are astounding. | ||
202 | 10:04 | And there's even potential in lab-grown or cell-based meats. | ||
203 | 10:08 | Uma Valeti fed me my first plate of lab-grown duck breast, | ||
204 | 10:13 | harvested fresh from a bioreactor. | ||
205 | 10:16 | It had been grown from a small sampling of cells | ||
206 | 10:18 | taken from muscle tissue and fat and connective tissues, | ||
207 | 10:23 | which is exactly what we eat when we eat meat. | ||
208 | 10:26 | This lab-grown or cell-based duck meat | ||
209 | 10:28 | has very little threat of bacterial contamination, | ||
210 | 10:31 | it's about 85 percent lower CO2 emissions associated with it. | ||
211 | 10:35 | Eventually it can be grown | ||
212 | 10:37 | like those crops inside vertical farms in decentralized facilities | ||
213 | 10:42 | that aren't vulnerable to supply-chain disruptions. | ||
214 | 10:45 | Valeti started out as a cardiologist, | ||
215 | 10:47 | who understood that doctors have been developing | ||
216 | 10:52 | human and animal tissues in laboratories for decades. | ||
217 | 10:55 | He was inspired as much by that | ||
218 | 10:58 | as he was by a 1931 quote from Winston Churchill that says, | ||
219 | 11:02 | "We shall escape the absurdity of growing the whole chicken | ||
220 | 11:05 | in order to eat the breast or the wing, | ||
221 | 11:08 | by growing them separately in suitable mediums." | ||
222 | 11:12 | Like Heraud, Valeti is a quintessential third-way thinker. | ||
223 | 11:16 | He's reimagined an old idea using new technology, | ||
224 | 11:20 | to usher in a solution whose time has come. | ||
225 | 11:24 | I've met with dozens of farmers and entrepreneurs and engineers | ||
226 | 11:29 | who emulate third-way thinking, all over the world. | ||
227 | 11:32 | They're using modern breeding tools like CRISPR | ||
228 | 11:35 | to develop nutritious heirloom crops that can withstand drought and heat. | ||
229 | 11:39 | They're using AI to make aquaculture sustainable. | ||
230 | 11:43 | They're finding ways to eliminate food waste. | ||
231 | 11:46 | They are scaling up | ||
232 | 11:47 | conservation agriculture and managed grazing. | ||
233 | 11:50 | And they're reviving ancient plants, | ||
234 | 11:52 | and they're recycling sewage and gray water | ||
235 | 11:54 | to develop a drought-proof water supply. | ||
236 | 11:58 | The upshot is this: | ||
237 | 12:00 | Human innovation that marries old and new approaches to food production | ||
238 | 12:05 | can, and I believe, will usher in this third way | ||
239 | 12:09 | and redefine sustainable food on a grand scale. |
