There’s a certain school of thought about sustainability that argues that the worst problem in the food system today is waste. The idea is that we expend a tremendous amount of resources — water, gasoline, fertilizer, pesticides, labor — growing food that never actually feeds anyone. Food waste advocates also argue that the world’s farms already produce enough food to end hunger for good, if only the food that’s currently thrown out could make it to the dinner plates of those in need.

The most obvious source of food waste is in the home. Who, after all, hasn’t had the experience of buying five or six bags of groceries at the supermarket, only to end up throwing out a good portion when it spoils before you have a chance to eat it?
