Many indigineous peoples uphold sustainability as crucial to their culture.

It is actually a common logical failing of Western thinking to assume that everyone sees the world and interacts with it the same way (like them). An unfortunate legacy of Eurocentrism during the colonial era.

The noble savage archetype itself came from Western schools of thought, and though it's now accepted as overly reductive, that doesn't mean that many Indigineous cultures do not live lives closer to nature and therefore put more thought into their ecological impact.

Indigineous cultures are layered and sophisticated. Some argue that principles of egalitarianism and self governance were introduced to englightenment thinkers through contact with Indigineous peoples in the Americas. Unfortunately a Eurocentric world view meant that crediting non European cultures for anything over most of the past 500 years has been discouraged.
