It is not man the ecological crisis threatens to destroy but the quality of human life.

It is possible to analyze the biological and social influences that make each human being unique, unprecedented, and unrepeatable, but this analysis does not explain how and why each feels different from all other human beings.

Man will survive as a species for one reason: He can adapt to the destructive effects of our power-intoxicated technology and of our ungoverned population growth, to the dirt, pollution and noise of a New York or Tokyo. And that is the tragedy. It is not man the ecological crisis threatens to destroy but the quality of human life.

It is a disturbing fact that Western civilization, which claims to have achieved the highest standard of health in history, finds itself compelled to spend ever-increasing sums for the control of disease.

Man shapes himself through decisions that shape his environment.

Eradication of microbial disease is a will-o'-the-wisp; pursuing it leads into a morass of hazy biological concepts and half truths.

Sometimes the more measurable drives out the most important.
