>My point in mentioning brown air was simply to say that the US is not the only one polluting.
I agree

>>Every country pollutes world, but USA pollutes more. That's true.

>Do you have some statistics to back that up?

Your country is number one for use energy on the world. And your country didn't signed Kyoto... :)


>...In addition, we are required to have cars inspected every year to make sure they meet clean air standards.
We are required every year, too. Addition my car has a system that testing it's exhaust gas every second for pollution.
But please don't name it as "clean air standards". Maybe more less dirty air standarts...


>You assume we are doing nothing to control pollution over here. You are wrong.

No, I didn't assume that. I'm sure USA doing somethings, but I think so USA should do more. Your country is worlds most developed country. So your country must do much and more.
