Co-existence between people and automobiles

More and more people buy cars, some people wonder why they do this because of are environment. People are saying that most of the people transported and most of the goods transported is because the help of automobiles. I think that more people should stop using cars and other transportation devices but it is addictive and they don't want to give up their luxury. I know it is hard to give up stuff but these things lead up to fatness and other body problems. I think the people that can go with out using the car once and awhile because it can hurt a lot of people and cause global warming and will hurt our children’s future. Further more a lot of people say yes we shouldn't do that but they end up doing it anyway. Plus no one would want to by an environment friendly car because they are so expensive. These are just some things that are affected.
