"Why are ecologists and environmentalists so feared and hated? This is because in part what they have to say is new to the general public, and the new is always alarming. Moreover, the practical recommendations deduced from ecological principles threaten the vested interests of commerce; it is hardly surprising that the financial and political power created by these investments should be used sometimes to suppress environmental impact studies. However, I think the major opposition to ecology has deeper roots than mere economics; ecology threatens widely held values so fundamental that they must be called religious. An attack on values is inevitably seen as an act of subversion."

“A coldly rationalist individualist can deny that he has any obligation to make sacrifices for the future. By contrast, those who, for whatever reason, regard the resources at their disposal as an inheritance from the past that they feel obliged to pass on to their descendants, have a better chance of producing future generations prosperous enough to be able to continue to wrestle with the problems of increasing the quality of life.”

“The class of "No technical solution problems" has members. My thesis is that the "population problem," as conventionally conceived, is a member of this class.”

“Many of the environmentalists who moved into the environmental movement after Silent Spring ... detested pollution and craved purity. Absolute purity. They wanted to enforce zero tolerance on all environmental pollutants, not just on carcinogens. With friends like these the environment needs no enemies.”

“But it is no good using the tongs of reason to pull the Fundamentalists' chestnuts out of the fire of contradiction. Their real troubles lie elsewhere ... Fundamentalists are panicked by the apparent disintegration of the family, the disappearance of certainty and the decay of morality. Fear leads them to ask, if we cannot trust the Bible, what can we trust? The truth or falsity of evolution is a secondary matter. Rationalists must listen to the complaints of the Fundamentalists with a psychiatrist's "third ear", and respond to the more subtle messages.”

“A finite world can support only a finite population; therefore, population growth must eventually equal zero.”

“Even at the religious level the creationist view is a biased one. The only creation story they mention is the one in Genesis . Why do they not mention the belief of the Hindus that the world began with the creation of the cosmic egg? What about the Babylonians' belief that there was not a single creationist god but two cosmic parents?”
