In the ideal society, the human actions would have no negative effects on the environment. However, no matter what we do, no matter how hard we try, we effect the environment. We do not fit into any ecosystem, and we do not give back to the planet.
What would happen if we end up eliminating big business? We would revert back to small town shops, ones that make less money and are incapable of 'protecting the environment.' No matter what we do, we find out twenty years later that it was worse than we were doing before.
What I am proposing is one of two things: Either stop the hippie movement - all it will do is make people angry over time, or have humans revert back to the hunter-gatherer society we used to be. We can either keep advancing, or we can fit back into the ecosystem.
