With shortages, volatile prices and nearly one billion people hungry, the world has a food problem-or thinks it does. Farmers, manufacturers, supermarkets and consumers in North America and Europe discard up to half of their food-enough to feed all the world's hungry at least three times over. Forests are destroyed and nearly one tenth of the West's greenhouse gas emissions are released growing food that will never be eaten. While affluent nations throw away food through neglect, in the developing world crops rot because farmers lack the means to process, store and transport them to market. But there could be painless remedies for what has become one of the world's most pressing environmental and social problems. 'Waste' traces the problem around the globe from the top to the bottom of the food production chain. Stuart's journey takes him from the streets of New York to China, Pakistan and Japan and back to his home in England. Introducing us to foraging pigs, potato farmers and food industry CEOs, Stuart encounters grotesque examples of profligacy, but also innovations and ways of making the most of what people have. The journey is a personal one, as Stuart is a dedicated freegan, who has chosen to live off of discarded or self-produced food in order to highlight the global food waste scandal.
