Every time I think about your last sentence...I smile. Oil, and our dependence on it has kept us running long enough that many of us are blissfully unaware of what real threat it's loss will mean for the future of our race (sometimes I suspect that was the intent behind switching our dependence from renewable resources, to non-renewables). It gives me a nice warm feeling inside knowing that, I know how to build a shelter, a fire, how to catch, and forage for food. I also know that so few people share the level of knowledge I possess, that I won't have to compete for food for long. First I will take to the hills, while they fight one another over cows, and other forms of farm food. Then they will look at one another as food, and after a few months there will only be those who thought far enough ahead to buy lots of ammo...and people like me. After their ammo is gone, I will come down from the hills, and try to assemble people who are smart enough not to over-populate to the point of exceeding an area's natural carrying capacity, and we'll re-create society in a way that balances our needs with nature's needs.
That is really where we as humans have gone horribly wrong. Whenever I hear some schmuck say "Human's first", I cringe because what they are saying is "It's ok to kill everything else, and spoil the environment in every way possible...as long as I get to keep my car, my ipod, my modern way of life". Well, to them I say, "You can't, and sooner than any of us expect, that lifestyle will no longer be possible...for anyone". It will take a decade or two, but we will get to a better level of existence. I just don't see this version of civilization lasting long enough to get all 8 BILLION+ of us there.
