If you want a tree for the holiday, the experts at Grist and TreeHugger say it's actually better to buy a cut real Christmas tree than an artificial tree.

Why? In a word, plastics. Fake trees are made of polyvinyl chloride (PVC). Producing this type of plastic creates a lot of pollution, and PVC is difficult to recycle.

Plus, lead has been found in PVC. According to a report (PDF) in the Journal of Environmental Health, lead levels are higher in older artificial trees. You've probably heard about lead in children's toys, so just imagine the kiddos hanging around lead-tainted branches of your fake Christmas tree. Not a merry scene.
