I'm hardly predicting a greener future- merely pointing out that our destructive capabilities are still outmatched by the Earth's destructive powers. I- and extinction researchers of all stripes- have taken into account the insane speed at which we spread extinction. (We actually started arpund 10k years ago). The numbers still don't even approach the big extinctions. In fact, the speed at which we're moving is the main reason why we're causing these extinctions- if human pressures had been applied slower, far more species could have adapted.

As for whether your claim is racist- well, you were the one who brought that into the conversation, so I think that's one you probably have the answer to already.
