I'm creating a world where it's impossible for human civilization do develop to the point that they could start seriously destroying habitats. I'm not even talking about the industrial revolution. Humans have had a big impact even before then. I believe forests in Europe were greatly reduced when the Age of Exploration started. Should I stop them from advancing past basic "put a thing in the ground and let it grow" agriculture? If so, how can I achieve this?
To be clear, I'm not talking about humans not hunting things to extinction. It's impossible to have humans on a planet and not have them do that. Also, it looks like agriculture already does severe damage to habitats. So should I do something to make agriculture completely unviable?
It's clear that my understanding was wrong from the beginning. Please close this question.
