In prosperous societies, roughly a third of all food produced is never eaten. This essay will examine why so much is thrown away and then outline the most effective remedies.
Two causes stand out. The first lies with consumers: food has become so cheap and abundant relative to incomes that wasting it carries no real pain. Households over-buy in bulk, cook more than they need, and misread date labels — discarding food that is merely past its “best before” date but perfectly safe. The second cause is built into the supply chain. Supermarkets reject fruit and vegetables for purely cosmetic imperfections, overstock shelves to look plentiful, and dump unsold goods, while restaurants serve oversized portions that end in the bin.
The solutions follow directly from these causes. Governments should first regulate the supply chain: France now forbids supermarkets from destroying unsold food, requiring donation to charities instead, and apps such as Too Good To Go let shops sell soon-to-expire items cheaply rather than discard them — models that measurably cut waste and deserve copying. Second, consumer behaviour must change through education and clearer labelling. Standardising date labels so that “best before” is no longer confused with “unsafe after”, teaching meal planning in schools, and charging for organic waste collection all make households feel the cost of what they throw away. Japan and South Korea, which weigh and charge for food waste, have shown how sharply habits respond.
In conclusion, food is wasted because abundance has made it feel valueless and because retail practices reward discarding, and the answer is to combine supply-chain regulation with clearer labels and consumer education. Both the causes and the cures, ultimately, are matters of incentive.
