text: It is understandable for one to not like the idea of reducing the usage of ones car, but if you sit back and realize it, cars are "responsible for 12 percent of green house gas emission" and thats just in Europe. In the United State, there percentage increases to 50 percent. All according to Elisabeth Rosenthal's article, In "German Suburb, Life Goes On Without Cars."  Beijing, Chine is guilty of being the "most poplluted cities in the whole world." Everyone is a culpret when it comes to poplution and that is why everyone should take time to look at the facts and change, help the earth that helps you. Instead of driving your car to work thats just down the street, take a bike, If not take a shuttle. Don't relie on one source of transportation.
