Relax. I don’t think the OP means there’s some genetic flaw in Europeans that makes them ecologically imbalanced by nature.

They’re saying that a lot of indigenous culture and practice was more sustainable. This may be for various reasons, and isn’t true only of American indigenous people but almost certainly people in Japan, India, Australia, etc., where urban civilization that depended on large scale agriculture didn’t take hold.

This is, if you see it, only evidence that there’s no inevitable path for progress and development for our species. We have the ability to look back, see how different parts of the world handled their engagement with their environment, when and where that degraded, and make changes, proving that none of this is inherent to any part of our species, but rather cultural and social structures that emerged for a bundle of reasons.
