Good tells you why you should:

It's December, and if you celebrate Christmas that means it's time to kill a tree, let it languish in your living room for a week, and then toss it on the curb. An estimated 32 million trees suffer this fate in America every year. The alternativebuying an artificial PVC tree from Chinais even worse.

But you don't have to go treeless. In Los Angeles, The Living Christmas Company will bring you a live, potted Christmas tree for the holiday, pick it up when you're done with it, and replant it. ...Their fleet of delivery trucks runs on biodiesel, of course, and they'll even pick up any Goodwill donations you have while they're at it.
