those people had no "competitors" until some neo-lib businessman decided to cut down the (adjacent) rainforest for cash.
Exactly. Their society was sustainable up until someone with superior technology showed up and destroyed it. Explain to me why we can dismiss this (wars of conquest) when looking for ways to create a sustainable world.
you are the media you consume.
It is unfortunate and sad when sustainable peoples fail to evade this Engine of Death. For in fact, the continuation of life will be possible only if they learn how to persist. Some may actually be doing that but here I hold my tongue.
For those of us who are already part of this Death Trip, we first have to decide if we want out of it or not, and secondly what that entails. It is all a gamble anyway: It may not be possible. But if it is, it is the one thing that would actually be worth doing.
Our "superior technology" is a delusion. Our whole way of life is a delusion--a drug binge that ends in the morgue.
Don't you understand? We have already LOST your Darwinian war of all against all, by choosing to fight it. The bacteria in your gut are superior to you: They will outlive you, and all humans. The Fates are kind.
A little furry Corporate animal is busily consuming all the Dinosaur eggs. The partnership-based entities I talk about are emerging because they "out compete" the existing corporates.
How? Because they do not have to pay a return to "rentiers".

On a more serious note: hunter-gathering lifestyle is not sustainable on a longer timeframe in the sense that the rise of a technological civilisation from it is possible. Hunter-gatherers weren't susptainable on a century timespan because they knew the danger, it's more they didn't knew how to be wasteful on a scale that it didn't just affect fellow humans, but the whole of the biosphere. *Lunatic*, n.
