Hello:
Are you carbon neutral? If you go to http://www.futureforests.com/indexch.html you can enter a calculator to see how much CO2 you produce, send them a check and they will plant the required number of trees to compensate for you. Then you can be carbon neutral too.
I heard about it today on NPR and I thought it was a great idea. They will even send you a map showing you where your tress are.
