WEBVTT 00:00:00.000 --> 00:00:04.939 [MUSIC PLAYING] 00:00:04.939 --> 00:00:11.856 00:00:11.856 --> 00:00:16.820 [APPLAUSE] 00:00:16.820 --> 00:00:24.030 ALLAN SAVORY: The most massive tsunami 00:00:24.030 --> 00:00:27.080 perfect storm is bearing down upon us. 00:00:27.080 --> 00:00:29.910 00:00:29.910 --> 00:00:36.060 This perfect storm is mounting a grim reality, increasingly grim 00:00:36.060 --> 00:00:37.690 reality. 00:00:37.690 --> 00:00:44.040 And we are facing that reality with a full belief 00:00:44.040 --> 00:00:46.710 that we can solve our problems with technology, 00:00:46.710 --> 00:00:49.050 and that's very understandable. 00:00:49.050 --> 00:00:53.560 Now this perfect storm that we are facing 00:00:53.560 --> 00:00:56.960 is the result of our rising population, rising 00:00:56.960 --> 00:01:01.940 towards 10 billion people, land that is turning to desert, 00:01:01.940 --> 00:01:05.099 and of course, climate change. 00:01:05.099 --> 00:01:07.850 Now there's no question about it at all. 00:01:07.850 --> 00:01:10.500 We will only solve the problem of replacing 00:01:10.500 --> 00:01:13.370 fossil fuels with technology. 00:01:13.370 --> 00:01:17.830 But fossil fuels-- carbon, coal, and gas-- are by no means 00:01:17.830 --> 00:01:22.830 the only thing that is causing climate change. 00:01:22.830 --> 00:01:27.530 Desertification is a fancy word for land 00:01:27.530 --> 00:01:32.040 that is turning to desert, and this happens only when 00:01:32.040 --> 00:01:34.240 we create too much bare ground. 00:01:34.240 --> 00:01:36.290 There's no other cause. 00:01:36.290 --> 00:01:40.270 And I intend to focus on most of the world's land 00:01:40.270 --> 00:01:41.895 that is turning to desert. 00:01:41.895 --> 00:01:44.510 00:01:44.510 --> 00:01:48.330 But I have for you a very simple message 00:01:48.330 --> 00:01:52.790 that offers more hope than you can imagine. 00:01:52.790 --> 00:01:55.800 We have environments where humidity is 00:01:55.800 --> 00:01:57.770 guaranteed throughout the year. 00:01:57.770 --> 00:02:00.570 On those, it is almost impossible 00:02:00.570 --> 00:02:04.620 to create vast areas of bare ground, no matter what you do. 00:02:04.620 --> 00:02:06.670 Nature covers it up so quickly. 00:02:06.670 --> 00:02:08.830 And we have environments where we 00:02:08.830 --> 00:02:12.860 have months of humidity followed by months of dryness, 00:02:12.860 --> 00:02:16.490 and that is where desertification is occurring. 00:02:16.490 --> 00:02:18.170 Fortunately, with space technology 00:02:18.170 --> 00:02:20.210 now, we can look at it from space. 00:02:20.210 --> 00:02:24.520 And when we do, you can see the proportions fairly well. 00:02:24.520 --> 00:02:27.820 Generally, what you see in green is not desertifying, 00:02:27.820 --> 00:02:30.400 and what you see in brown is. 00:02:30.400 --> 00:02:34.510 And these are by far the greatest areas of the Earth. 00:02:34.510 --> 00:02:39.250 About 2/3, I would guess, of the world is desertifying. 00:02:39.250 --> 00:02:42.200 I took this picture in the Tihamah Desert 00:02:42.200 --> 00:02:45.960 while 25 millimeters-- that's an inch of rain-- was falling. 00:02:45.960 --> 00:02:48.730 Think of it in terms of drums of water, 00:02:48.730 --> 00:02:52.190 each containing 200 liters. 00:02:52.190 --> 00:02:56.040 Over 1,000 drums of water fell on every hectare 00:02:56.040 --> 00:02:58.790 of that land that day. 00:02:58.790 --> 00:03:01.380 The next day, the land looked like this. 00:03:01.380 --> 00:03:03.930 Where had that water gone? 00:03:03.930 --> 00:03:06.430 Some of it ran off as flooding. 00:03:06.430 --> 00:03:09.340 But most of the water that soaked into the soil 00:03:09.340 --> 00:03:12.420 simply evaporated out again, exactly 00:03:12.420 --> 00:03:17.190 as it does in your garden if you leave the soil uncovered. 00:03:17.190 --> 00:03:20.910 Now because the fate of water and carbon 00:03:20.910 --> 00:03:25.790 are tied to soil organic matter, when we damage soils, 00:03:25.790 --> 00:03:27.820 you give off carbon. 00:03:27.820 --> 00:03:31.420 Carbon goes back to the atmosphere. 00:03:31.420 --> 00:03:35.150 Now you are told over and over, repeatedly, 00:03:35.150 --> 00:03:37.910 that desertification is only occurring 00:03:37.910 --> 00:03:42.310 in arid and semi-arid areas of the world, 00:03:42.310 --> 00:03:47.330 and that tall grasslands like this one, in high rainfall, 00:03:47.330 --> 00:03:49.290 are of no consequence. 00:03:49.290 --> 00:03:51.650 But if you do not look at grasslands 00:03:51.650 --> 00:03:54.400 but look down into them, you find 00:03:54.400 --> 00:03:57.890 that most of the soil in that grassland that you've just seen 00:03:57.890 --> 00:04:00.890 is bare and covered with a crust of algae, 00:04:00.890 --> 00:04:03.900 leading to increased runoff and evaporation. 00:04:03.900 --> 00:04:07.860 That is the cancer of desertification 00:04:07.860 --> 00:04:13.010 that we do not recognize till its terminal form. 00:04:13.010 --> 00:04:18.519 Now we know that desertification is caused by livestock, mostly 00:04:18.519 --> 00:04:23.270 cattle, sheep, and goats over-grazing the plants, 00:04:23.270 --> 00:04:27.540 leaving the soil bare, and giving off methane. 00:04:27.540 --> 00:04:31.350 Almost everybody knows this from Nobel laureates 00:04:31.350 --> 00:04:35.260 to golf caddies, or was taught it, as I was. 00:04:35.260 --> 00:04:39.420 Now the environments like you see here, dusty environments 00:04:39.420 --> 00:04:44.300 in Africa where I grew up-- and I loved wildlife. 00:04:44.300 --> 00:04:48.850 And so I grew up hating livestock because of the damage 00:04:48.850 --> 00:04:49.890 they were doing. 00:04:49.890 --> 00:04:53.370 And then my university education as an ecologist 00:04:53.370 --> 00:04:57.360 reinforced my beliefs. 00:04:57.360 --> 00:05:01.530 Well, I have news for you. 00:05:01.530 --> 00:05:06.910 We were once just as certain that the world was flat. 00:05:06.910 --> 00:05:11.050 We were wrong then, and we are wrong again. 00:05:11.050 --> 00:05:13.420 And I want to invite you now to come along 00:05:13.420 --> 00:05:20.260 on my journey of re-education and discovery. 00:05:20.260 --> 00:05:25.340 When I was a young man, a young biologist in Africa, 00:05:25.340 --> 00:05:29.400 I was involved in setting aside marvelous areas 00:05:29.400 --> 00:05:32.290 as future national parks. 00:05:32.290 --> 00:05:35.220 Now no sooner-- this was the 1950s-- 00:05:35.220 --> 00:05:38.460 and no sooner did we remove the hunting, 00:05:38.460 --> 00:05:42.890 drum beating people to protect the animals than the land began 00:05:42.890 --> 00:05:47.930 to deteriorate, as you see in this part that we formed. 00:05:47.930 --> 00:05:50.660 Now no livestock were involved. 00:05:50.660 --> 00:05:53.410 But suspecting that we had too many elephants 00:05:53.410 --> 00:05:58.500 now, I did the research, and I proved we had too many. 00:05:58.500 --> 00:06:01.830 And I recommended that we would have to reduce their numbers 00:06:01.830 --> 00:06:05.900 and bring them down to a level that the land could sustain. 00:06:05.900 --> 00:06:09.860 Now that was a terrible decision for me to have to make, 00:06:09.860 --> 00:06:12.500 and it was political dynamite, frankly. 00:06:12.500 --> 00:06:15.590 So our government formed a team of experts 00:06:15.590 --> 00:06:18.250 to evaluate my research. 00:06:18.250 --> 00:06:19.010 They did. 00:06:19.010 --> 00:06:20.460 They agreed with me. 00:06:20.460 --> 00:06:26.140 And over the following years, we shot 40,000 elephants 00:06:26.140 --> 00:06:28.780 to try to stop the damage. 00:06:28.780 --> 00:06:32.470 And it got worse, not better. 00:06:32.470 --> 00:06:37.010 Loving elephants as I do, that was the saddest and greatest 00:06:37.010 --> 00:06:41.060 blunder of my life, and I will carry that to my grave. 00:06:41.060 --> 00:06:43.430 One good thing did come out of it. 00:06:43.430 --> 00:06:47.530 It made me absolutely determined to devote 00:06:47.530 --> 00:06:49.862 my life to finding solutions. 00:06:49.862 --> 00:06:52.580 00:06:52.580 --> 00:06:54.640 When I came to the United States, 00:06:54.640 --> 00:06:59.220 I got a shock to find national parks like this one 00:06:59.220 --> 00:07:03.070 desertifying as badly as anything in Africa. 00:07:03.070 --> 00:07:07.760 And there'd been no livestock on this land for over 70 years. 00:07:07.760 --> 00:07:09.740 And I found that American scientists 00:07:09.740 --> 00:07:13.320 had no explanation for this except that it 00:07:13.320 --> 00:07:16.330 is arid and natural. 00:07:16.330 --> 00:07:21.350 So I then began looking at all the research 00:07:21.350 --> 00:07:25.210 plots I could over the whole of the western United States 00:07:25.210 --> 00:07:28.140 where cattle had been removed to prove that it 00:07:28.140 --> 00:07:29.990 would stop desertification. 00:07:29.990 --> 00:07:31.760 But I found the opposite. 00:07:31.760 --> 00:07:34.720 As we see on this research station 00:07:34.720 --> 00:07:40.490 where this grassland that was green in 1961, by 2002 00:07:40.490 --> 00:07:43.780 had changed to that situation. 00:07:43.780 --> 00:07:47.670 And the authors of the position paper on climate 00:07:47.670 --> 00:07:51.270 change from which I obtained these pictures attribute 00:07:51.270 --> 00:07:54.140 this change to unknown processes. 00:07:54.140 --> 00:07:57.140 00:07:57.140 --> 00:08:00.570 Clearly, we have never understood 00:08:00.570 --> 00:08:03.420 what is causing desertification, which 00:08:03.420 --> 00:08:08.990 has destroyed many civilizations and now threatens us globally. 00:08:08.990 --> 00:08:11.350 We have never understood it. 00:08:11.350 --> 00:08:14.330 Take one square meter of soil and make it bare 00:08:14.330 --> 00:08:17.090 like this is down here, and I promise you, 00:08:17.090 --> 00:08:22.620 you will find it much colder at dawn and much hotter at midday 00:08:22.620 --> 00:08:25.250 than that same piece of ground, if it's just covered 00:08:25.250 --> 00:08:27.390 with litter, plant litter. 00:08:27.390 --> 00:08:30.520 You have changed the microclimate. 00:08:30.520 --> 00:08:35.580 Now by the time you are doing that and increasing greatly 00:08:35.580 --> 00:08:41.500 the percentage of bare ground on more than half the world's 00:08:41.500 --> 00:08:45.390 land, you are changing macroclimate. 00:08:45.390 --> 00:08:48.140 But we have just simply not understood, 00:08:48.140 --> 00:08:52.080 why was it beginning to happen 10,000 years ago? 00:08:52.080 --> 00:08:54.730 Why has it accelerated lately? 00:08:54.730 --> 00:08:56.470 We had no understanding of that. 00:08:56.470 --> 00:09:00.470 What we had failed to understand was 00:09:00.470 --> 00:09:03.170 that the seasonal humidity environments 00:09:03.170 --> 00:09:06.960 of the world, the soil and the vegetation, 00:09:06.960 --> 00:09:12.770 developed with very large numbers of grazing animals, 00:09:12.770 --> 00:09:16.000 and that these grazing animals developed 00:09:16.000 --> 00:09:20.810 with ferocious pack-hunting predators. 00:09:20.810 --> 00:09:24.770 Now their main defense against pack-hunting predators 00:09:24.770 --> 00:09:26.660 is to get into herds. 00:09:26.660 --> 00:09:30.840 And the larger the herd, the safer the individuals. 00:09:30.840 --> 00:09:35.910 Now large herds dung and urinate all over their own food, 00:09:35.910 --> 00:09:38.730 and they have to keep moving. 00:09:38.730 --> 00:09:42.200 And it was that movement that prevented the overgrazing 00:09:42.200 --> 00:09:46.430 of plants, while the periodic trampling ensured 00:09:46.430 --> 00:09:52.640 good cover of the soil, as we see where a herd has passed. 00:09:52.640 --> 00:09:57.570 This picture is a typical seasonal grassland. 00:09:57.570 --> 00:10:00.600 It has just come through four months of rain, 00:10:00.600 --> 00:10:04.080 and it's now going into eight months of dry season. 00:10:04.080 --> 00:10:07.880 And watch the change as it goes into this long dry season. 00:10:07.880 --> 00:10:11.220 Now all of that grass you see above ground 00:10:11.220 --> 00:10:16.990 has to decay biologically before the next growing season. 00:10:16.990 --> 00:10:22.440 And if it doesn't, the grassland and the soil begin to die. 00:10:22.440 --> 00:10:25.670 Now if it does not decay biologically, 00:10:25.670 --> 00:10:30.630 it shifts to oxidation, which is a very slow process, 00:10:30.630 --> 00:10:35.020 and this smothers and kills grasses, leading to a shift 00:10:35.020 --> 00:10:40.660 to woody vegetation and bare soil releasing carbon. 00:10:40.660 --> 00:10:45.280 To prevent that, we have traditionally used fire. 00:10:45.280 --> 00:10:50.970 But fire also leaves the soil bare, releasing carbon. 00:10:50.970 --> 00:10:55.890 And worse than that, burning one hectare of grassland 00:10:55.890 --> 00:11:02.300 gives off more and more damaging pollutants than 6,000 cars. 00:11:02.300 --> 00:11:07.120 And we are burning in Africa, every single year, 00:11:07.120 --> 00:11:11.170 more than one billion hectares of grasslands, 00:11:11.170 --> 00:11:15.170 and almost nobody is talking about it. 00:11:15.170 --> 00:11:19.180 We justify the burning as scientists 00:11:19.180 --> 00:11:22.040 because it does remove the dead material, 00:11:22.040 --> 00:11:25.130 and it allows the plants to grow. 00:11:25.130 --> 00:11:28.380 Now looking at this grassland of ours that has gone dry, 00:11:28.380 --> 00:11:30.910 what can we do to keep that healthy? 00:11:30.910 --> 00:11:35.040 And bear in mind, I'm talking of most of the world's land now? 00:11:35.040 --> 00:11:40.110 We cannot reduce animal numbers to rest it more without causing 00:11:40.110 --> 00:11:42.580 desertification and climate change. 00:11:42.580 --> 00:11:46.660 We cannot burn it without causing desertification 00:11:46.660 --> 00:11:47.980 and climate change. 00:11:47.980 --> 00:11:49.300 What are we going to do? 00:11:49.300 --> 00:11:54.260 00:11:54.260 --> 00:11:56.340 There is only one option. 00:11:56.340 --> 00:12:00.750 I repeat to you, only one option left to climatologists 00:12:00.750 --> 00:12:05.220 and scientists, and that is to do the unthinkable, 00:12:05.220 --> 00:12:10.350 and to use livestock, bunched and moving, 00:12:10.350 --> 00:12:15.680 as a proxy for former herds and predators and mimic nature. 00:12:15.680 --> 00:12:20.370 There is no other alternative left to mankind. 00:12:20.370 --> 00:12:22.520 So let's do that. 00:12:22.520 --> 00:12:24.070 So on this bit of grassland, we'll 00:12:24.070 --> 00:12:25.720 do it, but just in the foreground. 00:12:25.720 --> 00:12:29.470 We'll impact it very heavily with cattle to mimic nature, 00:12:29.470 --> 00:12:32.080 and we've done so, and look at that. 00:12:32.080 --> 00:12:35.610 All of that grass is now covering the soil 00:12:35.610 --> 00:12:39.370 as dung, urine, and litter or mulch, 00:12:39.370 --> 00:12:42.780 as every one of the gardeners amongst you would understand, 00:12:42.780 --> 00:12:47.190 and that soil is ready to absorb and hold the rain, 00:12:47.190 --> 00:12:52.190 to store carbon, and to break down methane. 00:12:52.190 --> 00:12:56.870 And we did that without using fire to damage the soil, 00:12:56.870 --> 00:12:59.950 and the plants are free to grow. 00:12:59.950 --> 00:13:04.750 When I first realized that we had no option as scientists 00:13:04.750 --> 00:13:10.090 but to use much vilified livestock to address climate 00:13:10.090 --> 00:13:15.030 change and desertification, I was faced with a real dilemma. 00:13:15.030 --> 00:13:17.070 How were we to do it? 00:13:17.070 --> 00:13:20.600 We'd had 10,000 years of extremely knowledgeable 00:13:20.600 --> 00:13:23.360 pastoralists, bunching and moving their animals. 00:13:23.360 --> 00:13:27.060 But they had created the great man-made deserts of the world. 00:13:27.060 --> 00:13:31.250 Then we'd had 100 years of modern range science, 00:13:31.250 --> 00:13:34.220 and that had accelerated desertification 00:13:34.220 --> 00:13:37.300 as we first discovered in Africa and then confirmed 00:13:37.300 --> 00:13:39.630 in the United States, and as you see 00:13:39.630 --> 00:13:44.690 in this picture of land managed by the federal government. 00:13:44.690 --> 00:13:47.440 Clearly, more was needed than bunching and moving 00:13:47.440 --> 00:13:48.560 the animals. 00:13:48.560 --> 00:13:52.310 And humans, over thousands of years, 00:13:52.310 --> 00:13:56.340 had never been able to deal with nature's complexity. 00:13:56.340 --> 00:13:59.110 But we biologists and ecologists had never 00:13:59.110 --> 00:14:01.820 tackled anything as complex as this. 00:14:01.820 --> 00:14:04.370 So rather than reinvent the wheel, 00:14:04.370 --> 00:14:06.440 I began studying other professions 00:14:06.440 --> 00:14:08.730 to see if anybody had. 00:14:08.730 --> 00:14:11.210 And I found they we're planning techniques 00:14:11.210 --> 00:14:14.860 that I could take and adapt to our biological need. 00:14:14.860 --> 00:14:17.160 And from those, I developed what we 00:14:17.160 --> 00:14:21.830 call holistic management and planned grazing, a planning 00:14:21.830 --> 00:14:22.710 process. 00:14:22.710 --> 00:14:26.470 And that does address all of nature's complexity 00:14:26.470 --> 00:14:31.490 and our social, environmental, economic complexity. 00:14:31.490 --> 00:14:35.600 Today, we have a young woman like this one teaching villages 00:14:35.600 --> 00:14:37.920 in Africa how to put their animals together 00:14:37.920 --> 00:14:42.300 into larger herds, plan their grazing, to mimic nature. 00:14:42.300 --> 00:14:46.320 And where we have them hold their animals overnight-- 00:14:46.320 --> 00:14:48.275 we run them in a predator-friendly manner, 00:14:48.275 --> 00:14:50.660 because we have a lot of lands, and so on-- 00:14:50.660 --> 00:14:53.020 and where they do this and hold them overnight 00:14:53.020 --> 00:14:55.110 to prepare the crop fields, we're 00:14:55.110 --> 00:14:59.120 getting very great increases in crop yield as well. 00:14:59.120 --> 00:15:00.610 Let's look at some results. 00:15:00.610 --> 00:15:04.880 This is land close to land that we manage in Zimbabwe. 00:15:04.880 --> 00:15:06.890 It has just come through four months 00:15:06.890 --> 00:15:09.290 of very good rains it got that year, 00:15:09.290 --> 00:15:11.760 and it's going into the long dry season. 00:15:11.760 --> 00:15:14.700 But as you can see, all of that rain, almost all of it, 00:15:14.700 --> 00:15:18.070 has evaporated from the soil surface. 00:15:18.070 --> 00:15:22.430 The river is dry, despite the rain just having ended, 00:15:22.430 --> 00:15:28.950 and we have 150,000 people on almost permanent food aid. 00:15:28.950 --> 00:15:33.610 Now let's go to our land nearby on the same day 00:15:33.610 --> 00:15:36.530 with the s rainfall and look at that. 00:15:36.530 --> 00:15:38.880 Our river is flowing and healthy and clean. 00:15:38.880 --> 00:15:41.490 It's fine. 00:15:41.490 --> 00:15:48.020 The production of grass, shrubs, trees, wildlife, everything 00:15:48.020 --> 00:15:49.730 is now more productive. 00:15:49.730 --> 00:15:54.280 And we have virtually no fear of dry years. 00:15:54.280 --> 00:16:01.210 And we did that by increasing the cattle and goats 400%, 00:16:01.210 --> 00:16:05.240 planning the grazing to mimic nature and integrate them 00:16:05.240 --> 00:16:08.740 with all the elephants, buffalo, giraffe, and other animals 00:16:08.740 --> 00:16:10.400 that we have. 00:16:10.400 --> 00:16:12.990 But before we began, our land looked like that. 00:16:12.990 --> 00:16:16.140 00:16:16.140 --> 00:16:22.450 This site was bare and eroding for over 30 years, regardless 00:16:22.450 --> 00:16:24.770 of what rain we got. 00:16:24.770 --> 00:16:29.490 Watch the marked tree and see the change as we used livestock 00:16:29.490 --> 00:16:31.330 to mimic nature. 00:16:31.330 --> 00:16:35.230 This was another site where it had been bare and eroding, 00:16:35.230 --> 00:16:38.020 and at the base of the marked small tree, 00:16:38.020 --> 00:16:42.330 we had lost over 30 centimeters of soil. 00:16:42.330 --> 00:16:45.890 And again, watch the change just using livestock 00:16:45.890 --> 00:16:46.990 to mimic nature. 00:16:46.990 --> 00:16:48.800 And there are fallen trees in that 00:16:48.800 --> 00:16:52.090 now, because the better land is now attracting 00:16:52.090 --> 00:16:53.930 elephants, et cetera. 00:16:53.930 --> 00:16:57.450 This land in Mexico was in terrible condition. 00:16:57.450 --> 00:17:00.480 And I've had to mark the hill because the change 00:17:00.480 --> 00:17:03.180 is so profound. 00:17:03.180 --> 00:17:08.079 [APPLAUSE] 00:17:08.079 --> 00:17:11.520 00:17:11.520 --> 00:17:16.339 I began helping a family in the Karoo desert in the 1970s 00:17:16.339 --> 00:17:18.589 turn the desert that you see on the right 00:17:18.589 --> 00:17:21.130 there back to grassland. 00:17:21.130 --> 00:17:23.450 And thankfully, now their grandchildren 00:17:23.450 --> 00:17:26.618 are on the land with hope for the future. 00:17:26.618 --> 00:17:29.000 And look at the amazing change in this one 00:17:29.000 --> 00:17:34.070 where that gully has completely healed using nothing 00:17:34.070 --> 00:17:36.610 but livestock mimicking nature. 00:17:36.610 --> 00:17:39.590 And once more, we have the third generation 00:17:39.590 --> 00:17:44.210 of that family on that land with their flag still flying. 00:17:44.210 --> 00:17:47.390 The vast grasslands of Patagonia are turning to desert, 00:17:47.390 --> 00:17:48.340 as you see here. 00:17:48.340 --> 00:17:51.860 The man in the middle is an Argentinean researcher, 00:17:51.860 --> 00:17:54.520 and he has documented the steady decline 00:17:54.520 --> 00:17:57.100 of that land over the years as they kept 00:17:57.100 --> 00:17:59.780 reducing the sheep numbers. 00:17:59.780 --> 00:18:03.910 They put 25,000 sheep in one flock, 00:18:03.910 --> 00:18:08.480 really mimicking nature now with planned grazing. 00:18:08.480 --> 00:18:11.920 And they have documented a 50% increase 00:18:11.920 --> 00:18:15.290 in the production of the land in the first year. 00:18:15.290 --> 00:18:19.700 We now have in the violent Horn of Africa pastoralists 00:18:19.700 --> 00:18:22.070 planning their grazing to mimic nature, 00:18:22.070 --> 00:18:24.910 and openly saying it is the only hope they 00:18:24.910 --> 00:18:28.530 have of saving their families and saving their culture. 00:18:28.530 --> 00:18:34.240 95% of that land can only feed people from animals. 00:18:34.240 --> 00:18:38.410 I remind you that I am talking about most of the world's land 00:18:38.410 --> 00:18:41.390 here that controls our fate, including 00:18:41.390 --> 00:18:46.150 the most violent region of the world where only animals can 00:18:46.150 --> 00:18:50.670 feed people from about 95% of the land. 00:18:50.670 --> 00:18:55.630 What we are doing globally is causing climate change 00:18:55.630 --> 00:18:59.290 as much as, I believe, fossil fuels, and maybe 00:18:59.290 --> 00:19:02.050 more than fossil fuels. 00:19:02.050 --> 00:19:06.090 But worse than that, it is causing hunger, poverty, 00:19:06.090 --> 00:19:08.990 violence, social breakdown, and war. 00:19:08.990 --> 00:19:12.530 And as I am talking to you, millions 00:19:12.530 --> 00:19:16.680 of men, women, and children are suffering and dying. 00:19:16.680 --> 00:19:21.450 And if this continues, we are unlikely to be 00:19:21.450 --> 00:19:23.580 able to stop the climate changing, 00:19:23.580 --> 00:19:28.670 even after we have eliminated the use of fossil fuels. 00:19:28.670 --> 00:19:33.860 I believe I've shown you how we can work with nature at very 00:19:33.860 --> 00:19:37.860 low cost to reverse all this. 00:19:37.860 --> 00:19:44.090 We are already doing so on about 15 million hectares 00:19:44.090 --> 00:19:46.460 on five continents. 00:19:46.460 --> 00:19:50.440 And people who understand far more about carbon than I do 00:19:50.440 --> 00:19:53.480 calculate that for illustrative purposes, 00:19:53.480 --> 00:19:56.550 if we do what I'm showing you here, 00:19:56.550 --> 00:20:00.430 we can take enough carbon out of the atmosphere 00:20:00.430 --> 00:20:04.690 and safely store it in the grassland soils for thousands 00:20:04.690 --> 00:20:05.470 of years. 00:20:05.470 --> 00:20:10.460 And if we just do that on about half the world's grasslands 00:20:10.460 --> 00:20:12.870 that I've shown you, we can take us 00:20:12.870 --> 00:20:17.200 back to pre-industrial levels while feeding people. 00:20:17.200 --> 00:20:20.180 I can think of almost nothing that 00:20:20.180 --> 00:20:25.510 offers more hope for our planet, for your children 00:20:25.510 --> 00:20:28.160 and their children, and all of humanity. 00:20:28.160 --> 00:20:29.100 Thank you. 00:20:29.100 --> 00:20:33.244 [APPLAUSE AND CHEERING] 00:20:33.244 --> 00:20:53.004 00:20:53.004 --> 00:20:54.845 Thank you, Chris. 00:20:54.845 --> 00:20:55.755 Thank you. 00:20:55.755 --> 00:20:57.360 CHRIS: Thank you. 00:20:57.360 --> 00:21:01.630 I have-- and I'm sure everyone here has, A, 100 questions, B, 00:21:01.630 --> 00:21:02.650 wants to hug you. 00:21:02.650 --> 00:21:03.635 [LAUGHTER] 00:21:03.635 --> 00:21:05.510 I'm just going to ask you one quick question. 00:21:05.510 --> 00:21:09.680 When you first start this, you bring in a flock of animals. 00:21:09.680 --> 00:21:10.930 It's desert. 00:21:10.930 --> 00:21:11.710 What do they eat? 00:21:11.710 --> 00:21:12.740 How does that part work? 00:21:12.740 --> 00:21:13.470 How do you start? 00:21:13.470 --> 00:21:15.636 ALLAN SAVORY: Well, we've done this for a long time, 00:21:15.636 --> 00:21:19.040 and the only time we have ever had to provide any food 00:21:19.040 --> 00:21:22.960 is doing mine reclamation where it's 100% bare. 00:21:22.960 --> 00:21:27.820 But many years ago, we took the worst land in Zimbabwe 00:21:27.820 --> 00:21:32.620 where I offered a five-pound note in a 100-mile drive 00:21:32.620 --> 00:21:36.690 if somebody could find one grass in a 100-mile drive. 00:21:36.690 --> 00:21:39.870 And on that, we'd trebled the stocking rate, the number 00:21:39.870 --> 00:21:43.150 of animals, in the first year with no feeding, 00:21:43.150 --> 00:21:46.350 just by the movement mimicking nature and using 00:21:46.350 --> 00:21:50.610 a sigmoid curve, that principle. 00:21:50.610 --> 00:21:52.839 It's a little bit technical to explain here. 00:21:52.839 --> 00:21:54.380 CHRIS: Well, I would love t-- I mean, 00:21:54.380 --> 00:21:56.780 this is such an interesting and important idea. 00:21:56.780 --> 00:21:59.321 The best people s our blog are going to come and talk to you, 00:21:59.321 --> 00:22:02.880 and I want to get more on this that we can share, along 00:22:02.880 --> 00:22:04.485 with the talk. 00:22:04.485 --> 00:22:06.480 That is an astonishing talk. 00:22:06.480 --> 00:22:07.890 Truly an astonishing talk. 00:22:07.890 --> 00:22:09.412 And I think you heard that we all 00:22:09.412 --> 00:22:10.620 are cheering you on your way. 00:22:10.620 --> 00:22:11.330 Thank you so much. 00:22:11.330 --> 00:22:12.490 ALLAN SAVORY: Well, thank you. 00:22:12.490 --> 00:22:12.989 Thank you. 00:22:12.989 --> 00:22:13.894 Thank you, Chris. 00:22:13.894 -->
