Compost your Holiday Food Waste. Americans threw away more than 36 million tons of food in 2011. Almost all of that went to landfills, where it can decompose to produce methane, a greenhouse gas more than 20 times as potent as carbon dioxide. Composting it instead gives you rich soil for your plants and helps fight climate change. http://www2.epa.gov/recycle/composting-home
