Canadian supermarkets throw out billions of tons of good food each year

Canadian supermarkets throw out tons of unsold food every day. A common misunderstanding is that this food is rotten and useless. The truth is that most food thrown out is edible. Greenpeace is calling on supermarkets to reform their practices. They would like to see the big chains commit to a zero edible food waste target. We talk with Ann Foo, a volunteer with Go Zero Food Waste.
