“For the first time in the history of the world, every human being is now subjected to contact with dangerous chemicals, from the moment of conception until death.”

The human race is challenged more than ever before to demonstrate our mastery, not over nature but of ourselves.

We cannot have peace among men whose hearts find delight in killing any living creature.

For mankind as a whole, a possession infinitely more valuable than individual life is our genetic heritage, our link with past and future… Yet genetic deterioration through man-made agents is the menace of our time.

Like the resource it seeks to protect, wildlife conservation must be dynamic, changing as conditions change, seeking always to become more effective.

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.

But most of all I shall remember the monarchs, that unhurried westward drift of one small winged form after another, each drawn by some invisible force.

The Choice, after all, is ours to make.

It is ironic to think that man might determine his own future by something so seemingly trivial as the choice of an insect spray.

The control of nature is a phrase conceived in arrogance.

Wonder and humility are wholesome emotions and they do not exist side by side with a lust for destruction.

Knowing what I do, there would be no future peace for me if I kept silent.

[Writing is] largely a matter of application and hard work, or writing and rewriting endlessly until you are satisfied that you have said what you want to say as clearly and simply as possible. For me that usually means many, many revisions.

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.

Our attitude towards plants is a singularly narrow one. If we see any immediate utility in a plant we foster it. If for any reason we find its presence undesirable or merely a matter of indifference, we may condemn it to destruction forthwith.

The ‘control of nature’ is a phrase conceived in arrogance, born of the Neanderthal age of biology and philosophy, when it was supposed that nature exists for the convenience of man.
