Regarding the population level: Does anybody have a guess as to what a sustainable level of population in the States might be post PO? Many people use the world wide figure of 2 billion. In 1950 the world population was about 2,5 billion, and at that time the population of the States was 152 million. Yet the States has a low population density compared to many European countries.
"Sustainable" at what kind of living standard? Current SUV/McMansion standards? Hunter-gatherer standards? Or somewhere in between?
Estimates of the Native population in present-day Canada and the US prior to 1492 range from 1 million to 20 million, with most scholars estimating in the 4-10 million range. These people lived relatively lightly on the land (compared to us at least). They were pretty much all small-scale agriculturists and/or hunter-gatherers. As far as I know, none of them drove Hummers.
At our present rate of consumption, I'd venture to guess that a "sustainable" population level might be a couple orders of magnitude less than the current population.
