There is plenty of evidence that many environmental activists are, at bottom, dangerous extremists who have deluded themselves into believing that the earth's population must be radically reduced if humanity is to survive. There is also growing evidence that this far-out viewpoint is more widely accepted among so-called mainstream environmentalists than the establishment media would have us believe.

Occasionally, these views surface. Ted Turner, father of five, infamously asserted the need to reduce the earth's population to 2 billion about a decade ago. He also expressed a stronger personal preference: "Personally, I think the population should be closer to when we had indigenous populations, back before the advent of farming. Fifteen thousand years ago, there was somewhere between 40 and 100 million people." In the early 1990s, the late Jacques Cousteau suggested that "World population must be stabilized and to do that we must eliminate 350,000 people per day." More recently, though less famously, at a Psychology Today blog, writer Stephen Kotter asserted "we need to lose 4.4 billion people and we need to lose them fast."
