As the world changed, we reverted to social divisions that we'd thought were obsolete. The egalitarian pretenses of the high-octane decades had disso… - James Howard Kunstler

The attrition of global populations by disease[s] may be unavoidable. Some... may regard it as the inevitable revenge of nature against the hubris of a human species arrogantly exceeding the carrying capacity of its habitat. Some may regard it as a moral victory against wickedness. Some may view it in the therapeutic mode as a positive development for the health of the planet. Many self-conscious "humanists" have militated for the goal of reducing population growth—though most of them would have... preferred widespread birth control [using contraceptive methods like the birth pill and condoms, ironically made from cheap oil] to a die-off. But that kind of thinking might have been just another product of the narcotic comfort of cheap oil, as merely stabilizing the earth’s population at current levels (or even 1968 levels) would arguably still have left humanity beyond the earth’s carrying capacity. Apart from these issues of attitude and ethics, however, a major decline in world population, or change in demographic profiles, is apt to have profound and strange repercussions on everyday life.

Natural gas… is not as versatile as gasoline, but it does a lot of tasks beautifully. Gas is the feedstock—the raw material—for a wide array of chemicals, pharmaceuticals, and plastics. Ninety-five percent of the nitrogenous fertilizers used in America are made… of natural gas, and so it has become indispensable to U.S. agriculture.

The rebellion of the hippies… based itself on the notion that abundance was a natural entitlement, and one could "drop out" of an insecure, deadly, and frightening industrial culture to live off the fat of the land. It was inescapably a jejune philosophy, fraught with contradictions. For the hippies, the natural order of things included items such as stereo record players, electric guitars, motor vehicles for adventuring around the country, cheap bulk whole grains, and other products of an… industrial way of life. The hippie platform… with all its mystical incunabula, rested on the platform of “normal” American life and would have been impossible without it.
