The U.S. Department of Energy estimates that 60 million Americans have BBQs on the Fourth of July alone. These millions of BBQs release some 225,000 metric tons of carbon dioxide, burn the equivalent of 2,300 acres of forest and consume the same amount of energy as the city of Flagstaff, Arizona, uses in a year. Check out these tips on Nature.org — such as using reusable or biodegradable plates and utensils — that will help make sure your summer barbecue is environmentally-friendly.
