The global food waste scandal
The job of uncovering the global food waste scandal started for me when I was 15 years old. I bought some pigs. I was living in Sussex. And I started to feed them in the most traditional and environmentally friendly way. I went to my school kitchen, and I said, "Give me the scraps that my school friends have turned their noses up at." I went to the local baker and took their stale bread. I went to the local greengrocer, and I went to a farmer who was throwing away potatoes because they were the wrong shape or size for supermarkets. This was great. My pigs turned that food waste into delicious pork. I sold that pork to my school friends' parents, and I made a good pocket money addition to my teenage allowance.
But I noticed that most of the food that I was giving my pigs was in fact fit for human consumption, and that I was only scratching the surface, and that right the way up the food supply chain, in supermarkets, greengrocers, bakers, in our homes, in factories and farms, we were hemorrhaging out food. Supermarkets didn't even want to talk to me about how m
uch food they were wasting. I'd been round the back. I'd seen bins full of food being locked and then trucked off to landfill sites, and I thought, surely there is something more sensible to do with food than waste it.
One morning, when I was feeding my pigs, I noticed a particularly tasty-looking sun-dried tomato loafthat used to crop up from time to time. I grabbed hold of it, sat down, and ate my breakfast with my pigs. (Laughter) That was the first act of what I later learned to call freeganism, really an exhibition of the injustice of food waste, and the provision of the solution to food waste, which is simply to sit down and eat food, rather than throwing it away. That became, as it were, a way of confronting large businesses in the business of wasting food, and exposing, most importantly, to the public, that when we're talking about food being thrown away, we're not talking about rotten stuff, we're not talking aboutstuff that's beyond the pale. We're talking about good, fresh food that is being wasted on a colossal scale.
Eventually, I set about writing my book, really to demonstrate the extent of this problem o
n a global scale. What this shows is a nation-by-nation breakdown of the likely level of food waste in each country in the world. Unfortunately, empirical data, good, hard stats, don't exist, and therefore to prove my point, I first of all had to find some proxy way of uncovering how much food was being wasted. So I took the food supply of every single country and I compared it to what was actually likely to be being consumed in each country. That's based on diet intake surveys, it's based on levels of obesity, it's based on a range of factors that gives you an approximate guess as to how much food is actually going into people's mouths. That black line in the middle of that table is the likely level of consumption with an allowance for certain levels of inevitable waste. There will always be waste. I'm not that unrealistic that I think we can live in a waste-free world. But that black line shows what a food supply should be in a country if they allow for a good, stable, secure, nutritional diet for every person in that country. Any dot above that line, and you'll quickly notice that that includes most countries in the world, represents unnecessary surplus, and is likely to reflect ignore the waste behind youlevels of waste in each country.
As a country gets richer, it invests more and more in getting more and more surplus into it
s shops and restaurants, and as you can see, most European and North American countries fall between 150 and 200 percent of the nutritional requirements of their populations. So a country like America has twice as much food on its shop shelves and in its restaurants than is actually required to feed the American people.
But the thing that really struck me, when I plotted all this data, and it was a lot of numbers, was that you can see how it levels off. Countries rapidly shoot towards that 150 mark, and then they level off, and they don't really go on rising as you might expect. So I decided to unpack that data a little bit further to see if that was true or false. And that's what I came up with. If you include not just the food that ends upin shops and restaurants, but also the food that people feed to livestock, the maize, the soy, the wheat, that humans could eat but choose to fatten livestock instead to produce increasing amounts of meat and dairy products, what you find is that most rich countries have between three and four times the amount of food that their population needs to feed itself. A country like America has four times the amount of food that it needs.
When people talk about the need to increase global food production to feed those nine billion peoplethat are expected on the planet by 2050, I always think of these graphs. The fact is, we have an enormous buffer in rich countries between ourselves and hunger. We've never had such gargantuan surpluses before. In many ways, this is a great success story of human civilization, of the agricultural surpluses that we set out to achieve 12,000 years ago. It is a success story. It has been a success story. But what we have to recognize now is that we are reaching the ecological limits that our planet can bear, and when we chop down forests, as we are every day, to grow more and more food, when we extract water from depleting water reserves, when we emit fossil fuel emissions in the quest to grow more and more food, and then we throw away so much of it, we have to think about what we can start saving.
