Pollution thanks to super consumer's behavior is the greatest problem, I think. The churning of car fresheners that you talked about, for instance.

I am doing nothing, really. Just abandon a yard for a decade and watch trees appear on their own.

There are studies and date, though, that people begin caring for the environment, when their society is wealthy. Poor people have other problems on their mind and give no **** about their waste, bad habits, or anything else than finding the next meal. Gulls and cats do that, too. They attack a trash bin with vengeance and they leave all the trash spread around after they've managed to pull their treat out. It's a good thing they don't produce anything plastic.
