Every community ought to have a place where food can be left for other people. The food might be food that one realises one isn’t going to use before it is past its best, or it might be food bought impulsively, say, and no use will be made of it in that household. Rather than recycling food that has been wasted, food ought to be eaten, and this would be a good way for food to be eaten by people who would like to eat it.
