0:00:00.959,0:00:03.717 The job of uncovering the global food waste scandal 0:00:03.717,0:00:06.735 started for me when I was 15 years old. 0:00:06.735,0:00:09.256 I bought some pigs. I was living in Sussex. 0:00:09.256,0:00:11.639 And I started to feed them in the most traditional 0:00:11.639,0:00:13.610 and environmentally friendly way. 0:00:13.610,0:00:15.935 I went to my school kitchen, and I said, 0:00:15.935,0:00:17.481 "Give me the scraps that my school friends have turned 0:00:17.481,0:00:18.347 their noses up at." 0:00:18.347,0:00:21.011 I went to the local baker and took their stale bread. 0:00:21.011,0:00:23.743 I went to the local greengrocer, and I went to a farmer 0:00:23.743,0:00:25.581 who was throwing away potatoes because they were 0:00:25.581,0:00:28.767 the wrong shape or size for supermarkets. 0:00:28.767,0:00:31.856 This was great. My pigs turned that food waste 0:00:31.856,0:00:34.513 into delicious pork. I sold that pork 0:00:34.513,0:00:36.500 to my school friends' parents, and I made 0:00:36.500,0:00:41.137 a good pocket money addition to my teenage allowance. 0:00:41.137,0:00:44.019 But I noticed that most of the food that I was giving my pigs 0:00:44.019,0:00:46.402 was in fact fit for human consumption, 0:00:46.402,0:00:48.671 and that I was only scratching the surface, 0:00:48.671,0:00:51.533 and that right the way up the food supply chain, 0:00:51.533,0:00:54.751 in supermarkets, greengrocers, bakers, in our homes, 0:00:54.751,0:00:58.011 in factories and farms, we were hemorrhaging out food. 0:00:58.011,0:01:00.608 Supermarkets didn't even want to talk to me 0:01:00.608,0:01:01.982 about how much food they were wasting. 0:01:01.982,0:01:04.466 I'd been round the back. I'd seen bins full of food 0:01:04.466,0:01:07.217 being locked and then trucked off to landfill sites, 0:01:07.217,0:01:10.238 and I thought, surely there is something more sensible 0:01:10.238,0:01:13.405 to do with food than waste it. 0:01:13.405,0:01:15.710 One morning, when I was feeding my pigs, 0:01:15.710,0:01:19.397 I noticed a particularly tasty-looking sun-dried tomato loaf 0:01:19.397,0:01:21.472 that used to crop up from time to time. 0:01:21.472,0:01:22.874 I grabbed hold of it, 0:01:22.874,0:01:26.420 sat down, and ate my breakfast with my pigs. (Laughter) 0:01:26.420,0:01:29.540 That was the first act of what I later learned to call freeganism, 0:01:29.540,0:01:33.795 really an exhibition of the injustice of food waste, 0:01:33.795,0:01:36.145 and the provision of the solution to food waste, 0:01:36.145,0:01:38.799 which is simply to sit down and eat food, 0:01:38.799,0:01:40.287 rather than throwing it away. 0:01:40.287,0:01:43.566 That became, as it were, a way of confronting 0:01:43.566,0:01:46.553 large businesses in the business of wasting food, 0:01:46.553,0:01:49.074 and exposing, most importantly, to the public, 0:01:49.074,0:01:51.244 that when we're talking about food being thrown away, 0:01:51.244,0:01:53.383 we're not talking about rotten stuff, we're not talking about 0:01:53.383,0:01:56.095 stuff that's beyond the pale. 0:01:56.095,0:01:58.211 We're talking about good, fresh food that is being wasted 0:01:58.211,0:02:00.749 on a colossal scale. 0:02:00.749,0:02:02.606 Eventually, I set about writing my book, 0:02:02.606,0:02:04.660 really to demonstrate the extent of this problem 0:02:04.660,0:02:08.056 on a global scale. What this shows is 0:02:08.056,0:02:11.535 a nation-by-nation breakdown of the likely level 0:02:11.535,0:02:14.637 of food waste in each country in the world. 0:02:14.637,0:02:18.525 Unfortunately, empirical data, good, hard stats, don't exist, 0:02:18.525,0:02:21.007 and therefore to prove my point, I first of all had to find 0:02:21.007,0:02:23.160 some proxy way of uncovering 0:02:23.160,0:02:25.405 how much food was being wasted. 0:02:25.405,0:02:27.961 So I took the food supply of every single country 0:02:27.961,0:02:31.003 and I compared it to what was actually likely 0:02:31.003,0:02:33.035 to be being consumed in each country. 0:02:33.035,0:02:36.922 That's based on diet intake surveys, it's based on 0:02:36.922,0:02:39.588 levels of obesity, it's based on a range of factors 0:02:39.588,0:02:40.930 that gives you an approximate guess 0:02:40.930,0:02:44.157 as to how much food is actually going into people's mouths. 0:02:44.157,0:02:46.886 That black line in the middle of that table 0:02:46.886,0:02:49.882 is the likely level of consumption 0:02:49.882,0:02:54.244 with an allowance for certain levels of inevitable waste. 0:02:54.244,0:02:56.163 There will always be waste. I'm not that unrealistic 0:02:56.163,0:02:58.143 that I think we can live in a waste-free world. 0:02:58.143,0:03:02.016 But that black line shows what a food supply should be 0:03:02.016,0:03:06.470 in a country if they allow for a good, stable, secure, 0:03:06.470,0:03:10.219 nutritional diet for every person in that country. 0:03:10.219,0:03:12.626 Any dot above that line, and you'll quickly notice that 0:03:12.626,0:03:15.327 that includes most countries in the world, 0:03:15.327,0:03:19.616 represents unnecessary surplus, and is likely to reflect 0:03:19.616,0:03:22.238 levels of waste in each country. 0:03:22.238,0:03:25.507 As a country gets richer, it invests more and more 0:03:25.507,0:03:26.798 in getting more and more surplus 0:03:26.798,0:03:29.608 into its shops and restaurants, 0:03:29.608,0:03:31.664 and as you can see, most European 0:03:31.664,0:03:33.076 and North American countries 0:03:33.076,0:03:36.216 fall between 150 and 200 percent 0:03:36.216,0:03:39.596 of the nutritional requirements of their populations. 0:03:39.596,0:03:42.004 So a country like America has twice as much food 0:03:42.004,0:03:44.608 on its shop shelves and in its restaurants 0:03:44.608,0:03:48.176 than is actually required to feed the American people. 0:03:48.176,0:03:49.736 But the thing that really struck me, 0:03:49.736,0:03:53.951 when I plotted all this data, and it was a lot of numbers, 0:03:53.951,0:03:57.617 was that you can see how it levels off. 0:03:57.617,0:04:00.685 Countries rapidly shoot towards that 150 mark, 0:04:00.685,0:04:03.973 and then they level off, and they don't really go on rising 0:04:03.973,0:04:05.519 as you might expect. 0:04:05.519,0:04:08.064 So I decided to unpack that data a little bit further 0:04:08.064,0:04:10.349 to see if that was true or false. 0:04:10.349,0:04:11.843 And that's what I came up with. 0:04:11.843,0:04:13.770 If you include not just the food that ends up 0:04:13.770,0:04:15.894 in shops and restaurants, but also the food 0:04:15.894,0:04:18.050 that people feed to livestock, 0:04:18.050,0:04:21.553 the maize, the soy, the wheat, that humans could eat 0:04:21.553,0:04:24.034 but choose to fatten livestock instead to produce 0:04:24.034,0:04:25.965 increasing amounts of meat and dairy products, 0:04:25.965,0:04:27.632 what you find is that most rich countries 0:04:27.632,0:04:31.955 have between three and four times the amount of food 0:04:31.955,0:04:35.039 that their population needs to feed itself. 0:04:35.039,0:04:38.322 A country like America has four times the amount of food 0:04:38.322,0:04:41.284 that it needs. 0:04:41.284,0:04:44.246 When people talk about the need to increase global 0:04:44.246,0:04:46.906 food production to feed those nine billion people 0:04:46.906,0:04:49.418 that are expected on the planet by 2050, 0:04:49.418,0:04:51.139 I always think of these graphs. 0:04:51.139,0:04:54.090 The fact is, we have an enormous buffer 0:04:54.090,0:04:57.971 in rich countries between ourselves and hunger. 0:04:57.971,0:05:02.647 We've never had such gargantuan surpluses before. 0:05:02.647,0:05:05.313 In many ways, this is a great success story 0:05:05.313,0:05:09.452 of human civilization, of the agricultural surpluses 0:05:09.452,0:05:12.805 that we set out to achieve 12,000 years ago. 0:05:12.805,0:05:16.362 It is a success story. It has been a success story. 0:05:16.362,0:05:18.899 But what we have to recognize now is that we are 0:05:18.899,0:05:22.531 reaching the ecological limits that our planet can bear, 0:05:22.531,0:05:25.168 and when we chop down forests, as we are every day, 0:05:25.168,0:05:26.516 to grow more and more food, 0:05:26.516,0:05:30.264 when we extract water from depleting water reserves, 0:05:30.264,0:05:33.652 when we emit fossil fuel emissions in the quest 0:05:33.652,0:05:34.944 to grow more and more food, 0:05:34.944,0:05:37.795 and then we throw away so much of it, 0:05:37.795,0:05:40.731 we have to think about what we can start saving. 0:05:40.731,0:05:44.456 And yesterday, I went to one of the local supermarkets 0:05:44.456,0:05:46.672 that I often visit to 0:05:46.672,0:05:50.853 inspect, if you like, what they're throwing away. 0:05:50.853,0:05:53.256 I found quite a few packets of biscuits amongst 0:05:53.256,0:05:54.883 all the fruit and vegetables and everything else 0:05:54.883,0:05:55.830 that was in there. 0:05:55.830,0:05:58.270 And I thought, well this could serve as a symbol for today. 0:05:58.270,0:06:00.705 So I want you to imagine that these nine biscuits 0:06:00.705,0:06:04.233 that I found in the bin represent the global food supply, 0:06:04.233,0:06:05.834 okay? We start out with nine. 0:06:05.834,0:06:09.317 That's what's in fields around the world every single year. 0:06:09.317,0:06:11.078 The first biscuit we're going to lose 0:06:11.078,0:06:12.837 before we even leave the farm. 0:06:12.837,0:06:16.102 That's a problem primarily associated with 0:06:16.102,0:06:17.766 developing work agriculture, whether it's 0:06:17.766,0:06:20.271 a lack of infrastructure, refrigeration, pasteurization, 0:06:20.271,0:06:23.184 grain stores, even basic fruit crates, which means 0:06:23.184,0:06:26.933 that food goes to waste before it even leaves the fields. 0:06:26.933,0:06:30.429 The next three biscuits are the foods that we decide 0:06:30.429,0:06:34.169 to feed to livestock, the maize, the wheat and the soya. 0:06:34.169,0:06:39.013 Unfortunately, our beasts are inefficient animals, 0:06:39.013,0:06:43.188 and they turn two-thirds of that into feces and heat, 0:06:43.188,0:06:45.806 so we've lost those two, and we've only kept this one 0:06:45.806,0:06:48.040 in meat and dairy products. 0:06:48.040,0:06:51.624 Two more we're going to throw away directly into bins. 0:06:51.624,0:06:53.177 This is what most of us think of when we think 0:06:53.177,0:06:55.688 of food waste, what ends up in the garbage, 0:06:55.688,0:06:57.536 what ends up in supermarket bins, 0:06:57.536,0:07:00.266 what ends up in restaurant bins. We've lost another two, 0:07:00.266,0:07:04.024 and we've left ourselves with just four biscuits to feed on. 0:07:04.024,0:07:07.823 That is not a superlatively efficient use of global resources, 0:07:07.823,0:07:10.283 especially when you think of the billion hungry people 0:07:10.283,0:07:12.423 that exist already in the world. 0:07:12.423,0:07:14.406 Having gone through the data, I then needed 0:07:14.406,0:07:18.084 to demonstrate where that food ends up. 0:07:18.084,0:07:19.703 Where does it end up? We're used to seeing the stuff 0:07:19.703,0:07:21.606 on our plates, but what about all the stuff 0:07:21.606,0:07:23.546 that goes missing in between? 0:07:23.546,0:07:25.958 Supermarkets are an easy place to start. 0:07:25.958,0:07:28.549 This is the result of my hobby, 0:07:28.549,0:07:33.025 which is unofficial bin inspections. (Laughter) 0:07:33.025,0:07:35.622 Strange you might think, but if we could rely on corporations 0:07:35.622,0:07:38.730 to tell us what they were doing in the back of their stores, 0:07:38.730,0:07:41.214 we wouldn't need to go sneaking around the back, 0:07:41.214,0:07:43.770 opening up bins and having a look at what's inside. 0:07:43.770,0:07:45.730 But this is what you can see more or less on 0:07:45.730,0:07:49.242 every street corner in Britain, in Europe, in North America. 0:07:49.242,0:07:52.308 It represents a colossal waste of food, 0:07:52.308,0:07:54.810 but what I discovered whilst I was writing my book 0:07:54.810,0:07:58.154 was that this very evident abundance of waste 0:07:58.154,0:08:01.098 was actually the tip of the iceberg. 0:08:01.098,0:08:03.154 When you start going up the supply chain, 0:08:03.154,0:08:06.140 you find where the real food waste is happening 0:08:06.140,0:08:08.127 on a gargantuan scale. 0:08:08.127,0:08:09.600 Can I have a show of hands 0:08:09.600,0:08:14.058 if you have a loaf of sliced bread in your house? 0:08:14.058,0:08:15.977 Who lives in a household where that crust -- 0:08:15.977,0:08:19.170 that slice at the first and last end of each loaf -- 0:08:19.170,0:08:21.614 who lives in a household where it does get eaten? 0:08:21.614,0:08:23.981 Okay, most people, not everyone, but most people, 0:08:23.981,0:08:26.437 and this is, I'm glad to say, what I see across the world, 0:08:26.437,0:08:29.226 and yet has anyone seen a supermarket or sandwich shop 0:08:29.226,0:08:31.462 anywhere in the world that serves sandwiches 0:08:31.462,0:08:33.236 with crusts on it? (Laughter) 0:08:33.236,0:08:34.819 I certainly haven't. 0:08:34.819,0:08:39.987 So I kept on thinking, where do those crusts go? (Laughter) 0:08:39.987,0:08:42.202 This is the answer, unfortunately: 0:08:42.202,0:08:44.114 13,000 slices of fresh bread coming out of 0:08:44.114,0:08:49.715 this one single factory every single day, day-fresh bread. 0:08:49.715,0:08:51.224 In the same year that I visited this factory, 0:08:51.224,0:08:55.674 I went to Pakistan, where people in 2008 were going hungry 0:08:55.674,0:08:59.451 as a result of a squeeze on global food supplies. 0:08:59.451,0:09:01.635 We contribute to that squeeze 0:09:01.635,0:09:04.627 by depositing food in bins here in Britain 0:09:04.627,0:09:06.834 and elsewhere in the world. We take food 0:09:06.834,0:09:09.940 off the market shelves that hungry people depend on. 0:09:09.940,0:09:12.490 Go one step up, and you get to farmers, 0:09:12.490,0:09:14.650 who throw away sometimes a third or even more 0:09:14.650,0:09:16.695 of their harvest because of cosmetic standards. 0:09:16.695,0:09:19.618 This farmer, for example, has invested 16,000 pounds 0:09:19.618,0:09:23.042 in growing spinach, not one leaf of which he harvested, 0:09:23.042,0:09:25.496 because there was a little bit of grass growing in amongst it. 0:09:25.496,0:09:27.976 Potatoes that are cosmetically imperfect, 0:09:27.976,0:09:29.509 all going for pigs. 0:09:29.509,0:09:33.547 Parsnips that are too small for supermarket specifications, 0:09:33.547,0:09:35.563 tomatoes in Tenerife, 0:09:35.563,0:09:37.368 oranges in Florida, 0:09:37.368,0:09:40.372 bananas in Ecuador, where I visited last year, 0:09:40.372,0:09:42.787 all being discarded. This is one day's waste 0:09:42.787,0:09:45.324 from one banana plantation in Ecuador. 0:09:45.324,0:09:47.532 All being discarded, perfectly edible, 0:09:47.532,0:09:50.020 because they're the wrong shape or size. 0:09:50.020,0:09:51.600 If we do that to fruit and vegetables, 0:09:51.600,0:09:54.415 you bet we can do it to animals too. 0:09:54.415,0:09:57.154 Liver, lungs, heads, tails, 0:09:57.154,0:09:59.132 kidneys, testicles, 0:09:59.132,0:10:00.845 all of these things which are traditional, 0:10:00.845,0:10:03.660 delicious and nutritious parts of our gastronomy 0:10:03.660,0:10:07.156 go to waste. Offal consumption has halved 0:10:07.156,0:10:09.691 in Britain and America in the last 30 years. 0:10:09.691,0:10:12.331 As a result, this stuff gets fed to dogs at best, 0:10:12.331,0:10:14.100 or is incinerated. 0:10:14.100,0:10:17.947 This man, in Kashgar, Xinjiang province, in Western China, 0:10:17.947,0:10:19.862 is serving up his national dish. 0:10:19.862,0:10:21.577 It's called sheep's organs. 0:10:21.577,0:10:23.244 It's delicious, it's nutritious, 0:10:23.244,0:10:25.652 and as I learned when I went to Kashgar, 0:10:25.652,0:10:28.721 it symbolizes their taboo against food waste. 0:10:28.721,0:10:30.917 I was sitting in a roadside cafe. 0:10:30.917,0:10:33.521 A chef came to talk to me, I finished my bowl, 0:10:33.521,0:10:35.286 and halfway through the conversation, he stopped talking 0:10:35.286,0:10:37.852 and he started frowning into my bowl. 0:10:37.852,0:10:39.731 I thought, "My goodness, what taboo have I broken? 0:10:39.731,0:10:41.325 How have I insulted my host?" 0:10:41.325,0:10:43.063 He pointed at three grains of rice 0:10:43.063,0:10:47.347 at the bottom of my bowl, and he said, "Clean." (Laughter) 0:10:47.347,0:10:49.259 I thought, "My God, you know, I go around the world 0:10:49.259,0:10:50.675 telling people to stop wasting food. 0:10:50.675,0:10:55.724 This guy has thrashed me at my own game." (Laughter) 0:10:55.724,0:10:58.947 But it gave me faith. It gave me faith that we, the people, 0:10:58.947,0:11:03.983 do have the power to stop this tragic waste of resources 0:11:03.983,0:11:06.183 if we regard it as socially unacceptable 0:11:06.183,0:11:07.687 to waste food on a colossal scale, 0:11:07.687,0:11:10.240 if we make noise about it, tell corporations about it, 0:11:10.255,0:11:12.875 tell governments we want to see an end to food waste, 0:11:12.875,0:11:15.371 we do have the power to bring about that change. 0:11:15.371,0:11:18.083 Fish, 40 to 60 percent of European fish 0:11:18.083,0:11:21.164 are discarded at sea, they don't even get landed. 0:11:21.164,0:11:23.856 In our homes, we've lost touch with food. 0:11:23.856,0:11:26.773 This is an experiment I did on three lettuces. 0:11:26.773,0:11:29.411 Who keeps lettuces in their fridge? 0:11:29.411,0:11:32.987 Most people. The one on the left 0:11:32.987,0:11:34.440 was kept in a fridge for 10 days. 0:11:34.440,0:11:36.659 The one in the middle, on my kitchen table. Not much difference. 0:11:36.659,0:11:39.234 The one on the right I treated like cut flowers. 0:11:39.234,0:11:41.416 It's a living organism, cut the slice off, 0:11:41.416,0:11:42.859 stuck it in a vase of water, 0:11:42.859,0:11:46.407 it was all right for another two weeks after this. 0:11:46.407,0:11:48.366 Some food waste, as I said at the beginning, 0:11:48.366,0:11:50.198 will inevitably arise, so the question is, 0:11:50.198,0:11:52.396 what is the best thing to do with it? 0:11:52.396,0:11:53.902 I answered that question when I was 15. 0:11:53.902,0:11:59.312 In fact, humans answered that question 6,000 years ago: 0:11:59.312,0:12:01.524 We domesticated pigs 0:12:01.524,0:12:04.296 to turn food waste back into food. 0:12:04.296,0:12:08.027 And yet, in Europe, that practice has become illegal 0:12:08.027,0:12:11.314 since 2001 as a result of the foot-and-mouth outbreak. 0:12:11.314,0:12:13.215 It's unscientific. It's unnecessary. 0:12:13.215,0:12:15.898 If you cook food for pigs, just as if 0:12:15.898,0:12:18.867 you cook food for humans, it is rendered safe. 0:12:18.867,0:12:21.427 It's also a massive saving of resources. 0:12:21.427,0:12:24.322 At the moment, Europe depends on importing 0:12:24.322,0:12:25.988 millions of tons of soy from South America, 0:12:25.988,0:12:28.874 where its production contributes to global warming, 0:12:28.874,0:12:31.474 to deforestation, to biodiversity loss, 0:12:31.474,0:12:33.921 to feed livestock here in Europe. 0:12:33.921,0:12:36.223 At the same time we throw away millions of tons 0:12:36.223,0:12:39.442 of food waste which we could and should be feeding them. 0:12:39.442,0:12:42.304 If we did that, and fed it to pigs, we would save 0:12:42.304,0:12:44.655 that amount of carbon. 0:12:44.655,0:12:47.747 If we feed our food waste which is the current 0:12:47.747,0:12:50.042 government favorite way of getting rid of food waste, 0:12:50.042,0:12:52.843 to anaerobic digestion, which turns food waste 0:12:52.843,0:12:55.147 into gas to produce electricity, 0:12:55.147,0:12:58.880 you save a paltry 448 kilograms of carbon dioxide 0:12:58.880,0:13:01.362 per ton of food waste. It's much better to feed it to pigs. 0:13:01.362,0:13:04.622 We knew that during the war. (Laughter) 0:13:04.622,0:13:08.896 A silver lining: It has kicked off globally, 0:13:08.896,0:13:10.666 the quest to tackle food waste. 0:13:10.666,0:13:14.520 Feeding the 5,000 is an event I first organized in 2009. 0:13:14.520,0:13:16.776 We fed 5,000 people all on food that otherwise 0:13:16.776,0:13:18.174 would have been wasted. 0:13:18.174,0:13:20.474 Since then, it's happened again in London, 0:13:20.474,0:13:22.607 it's happening internationally, and across the country. 0:13:22.607,0:13:24.950 It's a way of organizations coming together 0:13:24.950,0:13:28.692 to celebrate food, to say the best thing to do with food 0:13:28.692,0:13:31.499 is to eat and enjoy it, and to stop wasting it. 0:13:31.499,0:13:34.092 For the sake of the planet we live on, 0:13:34.092,0:13:37.372 for the sake of our children, 0:13:37.372,0:13:38.942 for the sake of all the other 0:13:38.942,0:13:41.390 organisms that share our planet with us, 0:13:41.390,0:13:44.431 we are a terrestrial animal, and we depend on our land 0:13:44.431,0:13:47.053 for food. At the moment, we are trashing our land 0:13:47.053,0:13:49.567 to grow food that no one eats. 0:13:49.567,0:13:52.663 Stop wasting food. Thank you very much. (Applause) 0:13:52.663,0:13:55.222 (Applause)
