In developed countries, the leading source of waste are consumers themselves, who discard much of the food they purchase. In developing countries, insufficient cold storage and bad transportation result in food being lost before it even reaches the kitchen.

But there is even more to food waste. When banana and potato peels (and Original Beans chocolate packaging) degenerate in landfills, they can create the potent greenhouse gas methane. If you turn them into compost, they regenerate carbon into soils and become food for other organisms.
