Here we go. We (US) are the best stewards of the planet on the planet. Just during my lifetime people (everyone) have become more educated and such as regards pollution overall. You don't see now from individuals (changed oil poured into the sewer) what you saw in the '70s because people realize it's the wrong way to go about that. We can't control China, India or any of the others, and we are PRISTINE here compared to everywhere else. Nigeria dumps all their garbage on the beach. That's their dump. So the ocean fixes it, you know? India dumps it into the rivers, we just had a thread here. And China? You don't even want to know what China does. I'm not going to tell you because you'd have to take a couple days off protesting Trump to get hold of yourself.
But anyway, The United States is doing a hell of a job from an environmental standpoint. Nobody wants to mess shit up.
