Food does not appear on a plate — it travels a supply chain of five stages, and it loses mass at every one. Globally, roughly a third of all food grown for people is never eaten. Pick a food, set how much leaves the farm, and step through the chain to see where it goes — and how much water and greenhouse gas is thrown away with it.

Every kilogram lost is grown twice for nothing. The water, land, fuel, and fertiliser that went into food that is never eaten are spent all the same. Food loss and waste is estimated to drive around 8–10% of global greenhouse-gas emissions. strong evidence
