I will say that there were indigenous American tribes that weren't much better in terms of how they treated bison. Some hunted them pretty sustainably, but the Blackfoot believed that if you didn't kill the whole herd, the rest of them would learn to be wary of humans. So they drove the whole herd off a cliff. They only harvested a small portion of that herd when they were done, which is why there are just massive piles of bones at the bases of those cliffs.

Oh man, then don't look up what happened to the people that used to hunt these things.
