dh, I read more anger in your first post than in any other post I have seen on this sight so far, go back and review your intentions before accusing others.
as far as extinctions go, there is new evidence that native americans were responsible for the extinction of many species long before white man ever even thought about coming across the water.( mastedon, giant sloth etc.)
the only reason there was any game at all left was because of the no-mans land between waring tribes, where to hunt was to be in danger of being ambushed.
so you see your ancestors may not have been as enviromentally concious as you think.
p.s. your spelling sucks.
