You haven't addressed the fundamental problem. We must measure resources, we must not use them faster than they renew. No, you did not. You need other people to live. It does not matter what primitive level you go to, either.
People are interdependent.
Everyone seems willing to ignore me on this, so I will be willing to hurl it in your face as long as you ignore me. We are not going to get anywhere until we admit the basic facts of our existance. 6 billion people living on mined resources is what we have. If you started right this minute to put a moratorium on births, stopped growth of resource use right now, maybe by natural attrition you could get the population down, to something that could be sustainably maintained. But that is a joke.
