Depends on your definition of pollution. Except for certain very small areas the air and water quality in the US is as good or better than anywhere in the world. Our cars, trucks, factories are all clean enough, not perfect, but enough, and we are working on the toxic issues from the past. The thing you Euros don't get is we have vastly more land per person than you do, and a small amount of pollution is sustainable. Especially when to rid ourselves of any more pollution would cost either HUGE money or a drastic change in our lifestyle. SCREW that. When you can get ALL the little third world sh!tholes including Russia, China, India, and Pakistan to even agree to be as clean as us, come talk to me. Otherwise we are doing just fine as we are. And remember, CO2 is NOT a pollutant. It is a naturally occurring gas in our atmosphere that has never been proven to be a cause of any environmental issues. And paying ridiculous costs and taxes and making lifestyle changes over a rapidly falling apart THEORY is total folly.
