Right, which is exactly why I was confused!

And while the concept of environment may well be implied in any such treatment, there's always he question of "how much". Every animal has its niche and tolerance ranges. If we're pushed too far out of ours, yet a potential competitor still finds room to survive or even thrive, then we will have to move aside and call it quits whether we like it or not. And our sociosuicidal tendencies seem to be pushing for just such a scenario.

But now we're getting VERY off topic...

EDIT: hey, I apologize if I came across as combative. Not intended. just battling a headache...
