Exactly what TheGame said. If this does occur, then I do believe there could be a big dieoff of people occuring. Of course we lived just fine without oil, but that was when we had a balance of people on the planet that could be sustained of the amount of food we could produce without oil to back us up. The fact of the matter is, without oil, we have no way (right now) of maintaining the food/water/medical infrastructure that is keeping 6 billion people alive on the planet..
