Reducing food waste would also help fight climate change, as spoiled food ends up in landfills(垃圾堆） where it rots, releasing harmful greenhouse gasses, while the water, energy and fuel needed to grow, store and transport it is wasted.Saving 25 percent of it would be enough to feed the more than 800 million people that go to bed hungry every night21A Survey on Food Waste
