Reducing food waste can have myriad social, economic, and environmental benefits. But a new report has put a number to the impact on global warming that uneaten food has every year. "The world throws away one-third of food produced yearly, making food waste the third-largest source of greenhouse gas emissions behind those produced by the U.S. and China, according to a U.N. report released Wednesday," writes Ricardo Lopez. "[T]he U.N. estimated the carbon footprint of the problem is equivalent to 3.3 billion tons of carbon dioxide every year."

"All of us -- farmers and fishers, food processors and supermarkets, local and national governments, individual consumers -- must make changes at every link of the human food chain to prevent food wastage from happening in the first place, and re-use or recycle it when we can't," said FAO Director-General José Graziano da Silva.
