Living Planet: Deep dive into food waste

Why do we waste so much food? And what can we do about it? Neil King and Gabe Borrud get to the bottom of these questions on this week's Living Planet. They visit a supermarket to gauge their role as consumers, and team up with two dumpster diving sisters for a nighttime harvesting spree. They also talk to a leading food economist and discover the root of the food waste problem runs a lot deeper.
