Honestly, a long read that I didn’t finish.

However, I’ve long held the view that the Indian was not some benevolent caretaker of the land. The story goes that they were “environmentalists” would not over-hunt an area and move in order to allow game to re-establish itself.

Total BS. They were hunter-gatherers. When game became scarce they moved because it was a matter of survival! There was no conscious “steward of the land” garbage. They simply needed food and went where they found it.
