Be green: don't walk, drive a car

John Tierney has another interesting post about how much carbon dioxide gets produced from people walking instead of taking a car. Guess what? "Food production creates carbon emissions." Who would have guessed? Anyway, next time someone gives you a hard time for driving your car just tell them that you are doing what you can to save the planet.

(Of course, I don't take this carbon dioxide scare seriously. But if environmentalists were serious, they wouldn't be walking every place.)
