Tristram Stuart, the Food-Waste Rebel: When I was a teenager most of the food that I was giving my pigs was actually perfectly fit for human consumption. It was coming from supermarket dumpsters; bins full of food being locked and sent off to landfill sites. And I thought well I’m just scratching the surface here. At least a third of the world’s food supply is currently being wasted. When you add it all up it amounts to an enormous environmental catastrophe and a major contributor to the scarcity of food in some parts of the world. The ridiculously strict cosmetic standards laid down by supermarkets in Europe and America mean that farmers in Kenya waste thousands of tonnes of perfectly good food every single year right where there are millions of people hungry. This is the food waste from one day of packing, in one plant in Kenya. Multiply that by many times and you start to see the scale and the gratuitousness of the global food waste scandal.
