If you plant some trees, is it OK to drive an Escalade? The question isn't as silly as it sounds. People worried about global warming increasingly are trying to "offset" the carbon dioxide - the leading greenhouse gas - they spew into the atmosphere when they drive, fly or flick on a light. One idea popular with the eco-conscious is to have trees planted for them. You get to keep driving and flying, but those trees are supposed to suck in your trail of carbon.
