Walking is Green!

According to a CNN story, If each American walked for a half hour a day (the recommended minimum for good health) instead of driving, we would save the planet 64 million tons of carbon dioxide, 6.5 million gallons of gas, and incidentally lose 13 pounds a year. Not too shabby. I'm all for the global warming diet! There are tremendous benefits from becoming more active, especially if in doing so you can leave the car behind once in awhile.
