Can you really blame people, though? They didn't start the process, it was their ancestors and everyone who came before them who fucked nature up to whatever degree you're talking about.

Anyway; I guess I can answer a few questions as a spokesman for the human race; but don't expect me to have all the answers.

Where is nature? Who knows; wasn't there some kind of disaster here?

Who did this? The fuck should I know? Ask someone else.

Are we happy? I'd say so; usually destroying nature provides fuel and other bonuses to make life easier; it's a pretty sweet deal.
