Food waste worldwide
Food waste accounts for about 10% of global greenhouse gas emissions. An estimated billion tons of food, which is almost 20% of all food, is discarded yearly, while some 820 million people go hungry.
Food waste is also a waste of energy. Consider the fuel and water used to grow and harvest crops, transport those crops, and then process and package those crops as food items. When the unused food is thrown away to rot, it produces methane, a greenhouse gas that is 80 times more planet-warming than carbon.
