“The cheap oil age created an artificial bubble of plentitude for a period not much longer than a human lifetime, a hundred years.… So, I hazard to assert that as oil ceases to be cheap and the world reserves are toward depletion, we will indeed suddenly be left with an enormous surplus population … that the ecology of the earth will not support. No political program of birth control will avail. The people are already here. The journey back to non-oil population homeostasis will not be pretty. We will discover the hard way that population hypergrowth was simply a side effect of the oil age. It was a condition, not a problem with a solution. That is what happened and we are stuck with it. ”
