- Best-selling economist Robert Heilbroner in 1974: “The outlook for man, I believe, is painful, difficult, perhaps desperate, and the hope that can be held out for his future prospects seem to be very slim indeed.” Or best-selling ecologist Paul Ehrlich in 1968: “The battle to feed all of humanity is over. In the 1970s ["and 1980s" was added in a later edition] the world will undergo famines—hundreds of millions of people are going to starve to death in spite of any crash programs embarked on now … nothing can prevent a substantial increase in the world death rate.” Or Jimmy Carter in a televised speech in 1977: “We could use up all of the proven reserves of oil in the entire world by the end of the next decade.”
Predictions of global famine and the end of oil in the 1970s proved just as wrong as end-of-the-world forecasts from millennialist priests. Yet there is no sign that experts are becoming more cautious about apocalyptic promises. If anything, the rhetoric has ramped up in recent years. Echoing the Mayan calendar folk, the Bulletin of the Atomic Scientists moved its Doomsday Clock one minute closer to midnight at the start of 2012, commenting: “The global community may be near a point of no return in efforts to prevent catastrophe from changes in Earth’s atmosphere.”
Over the five decades since the success of Rachel Carson’s Silent Spring in 1962 and the four decades since the success of the Club of Rome’s The Limits to Growth in 1972, prophecies of doom on a colossal scale have become routine. Indeed, we seem to crave ever-more-frightening predictions—we are now, in writer Gary Alexander’s word, apocaholic. The past half century has brought us warnings of population explosions, global famines, plagues, water wars, oil exhaustion, mineral shortages, falling sperm counts, thinning ozone, acidifying rain, nuclear winters, Y2K bugs, mad cow epidemics, killer bees, sex-change fish, cell-phone-induced brain-cancer epidemics, and climate catastrophes.
So far all of these specters have turned out to be exaggerated. True, we have encountered obstacles, public-health emergencies, and even mass tragedies. But the promised Armageddons—the thresholds that cannot be uncrossed, the tipping points that cannot be untipped, the existential threats to Life as We Know It—have consistently failed to materialize. To see the full depth of our apocaholism, and to understand why we keep getting it so wrong, we need to consult the past 50 years of history.
