At least you realize the earth is billions of years old and you probably know that it didn't always have this comfortable oxygenated atmosphere (and someday won't). Maybe you also know that the atmosphere, relatively speaking, is thinner than the skin of a apple and the part important to us is even thinner. The man-made effects of affecting the atmosphere with fossil fuels is rally a little more than 100 yrs but for some reason you don't seem to understand that it's not the SUV it's the COAL. One coal fired generator (I think its in Georgia) is the equivalent of 3,000,000 cars.
I guess you think we can put as much of anything we want in the air and it won't bother you. You're not the only one who lives here, grow up.
