Christmas is officially over, which means taking down the lights, putting the chocolates away, and getting rid of your shedding tree.
According to the Nature Conservancy, some 10 million live Christmas trees end up in landfills every year. There, they are covered with soil, which results in anaerobic (oxygen-deprived) decomposition rather than the aerobic (oxygen-fueled) process by which they would break down in a natural setting, such as on the forest floor.
