This is what America looked like before the EPA cleaned it up

[Marthe48]

41. I was lamenting

if we lose EPA, corporations across the production spectrum will pollute and leave their mess. Because people are slobs, EPA could exist forever, and be lucky to stay ahead. But EPA has raised our consciousness about protecting the planet. Individuals, especially the younger generations, include recycling as a usual habit in their lives. And do other helpful things as well.

I almost think that pollution in a broad sense is innate behaviour in humans.
Early mankind ruined their local environment and when it got too nasty, moved. Or moved back and forth between seasonal camps, giving their garbage a chance to rot away. I don't have an example relating age-old actions to modern people dumping their ashtrays and fast food litter on the road or parking lot rather than using a waste can.

If you look at other primates, and watch them peel fruit, they drop the peels as they work. Now, imagine a human taking a wrapper off a candy bar. Usually same actions--peel and drop. It'd make an effective anti-littering message. Except the creationists would get mad at the comparison.
