The most alarming of all man's assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable; the chain of evil it initiates not only in the world that must support life but in living tissues is for the most part irreversible. In this now universal contamination of the environment, chemicals are the sinister and little-recognized partners of radiation in changing the very nature of the world-the very nature of its life.

We have been troubled about the world, and had almost lost faith in man; it helps to think about the long history of the earth, and of how life came to be. And when we think in terms of millions of years, we are not so impatient that our own problems be solved tomorrow.

Any concept of biology is not only sterile and profitless, it is distorted and untrue, if it puts its primary focus on unnatural conditions rather than on those vast forces not of man's making that shape and channel the nature and direction of life.

The 'control of nature' is a phrase conceived in arrogance, . . . when it was supposed that nature exists for the convenience of man . . . . It is our alarming misfortune that so primitive a science has armed itself with the most modern and terrible weapons, and that in turning them against the insects it has also turned them against the earth.

In recent years it has become impossible to talk about man's relation to nature without referring to "ecology"...such leading scientists in this area as Rachel Carson, Barry Commoner, Eugene Odum, Paul Ehrlich and others, have become our new delphic voices...so influential has their branch of science become that our time might well be called the "Age of Ecology".

In an age when man has forgotten his origins and is blind even to his most essential needs for survival, water along with other resources has become the victim of his indifference.

I still feel there is a case to be made for my old belief that as man approaches the 'new heaven and the new earth' -- or the space-age universe, if you will, he must do so with humility rather than with arrogance.

Here and there awareness is growing that man, far from being the overlord of all creation, is himself part of nature, subject to the same cosmic forces that control all other life. Man's future welfare and probably even his survival depend upon his learning to live in harmony, rather than in combat, with these forces.

We are not truly civilized if we concern ourselves only with the relation of man to man. What is important is the relation of man to all life.
