OK. A valid point.
My point is that the hunter-gatherer tribe or clan was in most places pretty small, probably no more than a couple dozen people. More like a large family than a tribe, really.
Back then to a very considerable extent people adapted to their environment rather than the other way around. Our ability to change the environment was quite limited.
A nomadic tribe needs about 50 sq miles per person to provide enough for their personal needs. Brain studies show that we’re good for about 150 people, before we have to break up tribes.
Yeah, most of us live in unpleasent urbanity.
