So, there were indigenous societies that were highly class stratified, or did bad things to the environment. No one is denying that.

But generally speaking, indigenous peoples in say, the Americas, developed methods of agriculture and other forms of production that were more ecologically sustainable for their respective continent, than the European methods that settlers brought, and then revised to be more extractive.

The dust bowl, for example, didn't just happen. It was a product of Colonialism. A region which was relatively recently colonized, had its forests and grasslands ripped up, in favor of shallow rooted monocultures that couldn't sustain drought conditions.

There weren't dustbowls for the millennia prior to colonization, but a sudden shift in the mode of production, to a highly extractive one, artificially produced an ecological disaster
