A new report by the UN Food and Agriculture Organization (FAO) has found that each year nearly a third of the food produced for human consumption worldwide — about 1.3 billion metric tons — is wasted, a practice which emits the equivalent of about 3.3 billion metric tons of greenhouse gases. If the amount of food wasted was a country, it would be the third largest emitter of greenhouse gases – right behind the US and China.
That wasted food also wastes water — the report states that about 250 cubic kilometers of ground and surface water is used each year to produce food that is ultimately wasted, an amount about three times the volume of Lake Geneva in Switzerland.
Because the ways food gets wasted differs by region (developing countries versus first world), there is no easy way to tackle the problem. Continue reading
