Save the planet - kill a tree

As the proud owner of not one, but two fake trees, imagine my sorrow joy when I learned that I am contributing to killing the planet!  (My two SUVs probably contribute, too.)

 It may not sound like "tree-hugging," but cutting down a real tree for Christmas is actually greener than going with the artificial kind, one scientist says.

 "It is a little counterintuitive to people," said Clint Springer, a biologist at Saint Joseph's University in Philadelphia.

[...]

 Live trees actively photosynthesize as they grow from saplings, which removes carbon dioxide from the atmosphere. After they have been cut and Christmas is over, they're usually chipped for mulch. As mulch, the bits of tree very slowly decompose, releasing carbon dioxide back into the atmosphere. So in the end, a real Christmas tree is carbon neutral, putting the same amount of carbon dioxide back into the air as it took out (albeit much more slowly).

 The tree farms that grew the trees also replant after the trees are cut.

 Artificial trees, on the other hand, don't come out even in the carbon balance. Petroleum is used to make the plastics in the trees and lots of carbon dioxide-creating energy is required to make and transport them.

 Because these trees just end up in landfills after a few years' use, "those greenhouse gases are lost forever," Springer said. "There's really no opportunity to recycle those."
