Recently, food waste, defined as food that is thrown away before or after it spoils, has been placed on the forefront of Americans鈥� minds. According to Rethink Food Waste Through Economics and Data (), awareness has increased for many reasons: to combat environmental degradation while feeding a growing population, to fix economic inefficiencies in the food supply chain, and to reduce greenhouse gas emissions coming from landfills.
A U.S.聽聽by the International Food Information Council Foundation explored why food waste happens at the consumer level. According to the results, eaters either forget about perishable food until it鈥檚 too late (19 percent), buy too much fresh or perishable food (17 percent), cook big meals and throw away leftovers (8 percent), or serve themselves portions that are too big (7 percent).

Many of those trailers would distribute food to grocery stores鈥nstead of being purchased, this perfectly good food would be loaded onto another line of trucks and hauled to a landfill.鈥�
The Environmental Protection Agency () declared that uneaten food in landfills accounts for roughly 20 percent of U.S. methane emissions. Plus, methane is about 27 times as potent as carbon dioxide at trapping heat. According to a 2016 study conducted by the Potsdam Institute for Climate Impact Research (), greenhouse gas emissions related to the food supply quadrupled during the last 50 years. 罢丑别听聽emphasizes the problem鈥攆ood is now the second-largest source of methane emission in the U.S.
