"If, having endured much, we have at last asserted out "right to know," and if by knowing, we have concluded that we are being asked to take senseless and frightening risks, then we should no longer accept the counsel of those who tell us that we must fill our world with poisonous chemicals; we should look about and see what other course is open to us."

To have risked so much in our efforts to mold nature to our satisfaction and yet to have failed in achieving our goal would indeed by the final irony. Yet this, it seems, is our situation.

Carson’s thesis that we were subjecting ourselves to slow poisoning by the misuse of chemical pesticides that polluted the environment may seem like common currency now, but in 1962 Silent Spring contained the kernel of social revolution.

Who could have foretold that this being, who walked upright and no longer lived in trees, who lurked in caves, hiding in fear from the great beasts who shared his world-who could have guessed that he would one day have in his hands the power to change the very nature of the earth-the of life and death over so many of its creatures? Who could have foretold that the brain that was developing behind those heavy brow ridges would allow him to accomplish things no other creature had achieved-but would not at the same time endow him with wisdom so to control his activities that he would not bring destruction upon himself?

For we all are united in a common cause. It is a proud cause, which we may serve secure in the knowledge that the earth will be better for our efforts. It is a cause that has no end: there is no point at which we shall say, "Our work is finished." We build on the achievements of those who have gone before us; let us, in turn, build strong foundations for those who will take up the work when we must lay it down.

I am not afraid of being thought a sentimentalist when I stand here tonight and tell you that I believe natural beauty has a necessary place in the spiritual development of any individual or any society. I believe that whenever we destroy beauty, or whenever we substitute something man-made and artificial for a natural feature of the earth, we have retarded some part of man's spiritual growth.

Although man’s record as a steward of the natural resources of the earth has been a discouraging one, there has long been a certain comfort in the belief that the sea, at least, was inviolate, beyond man’s ability to change and to despoil. But this belief, unfortunately, has proved to be naïve.

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

Fish, amphibian, and reptile, warm-blooded bird and mammal-each of us carries in our veins a salty stream in which the elements sodium, potassium, and calcium are combined in almost the same proportions as in sea water.

How could intelligent beings seek to control a few unwanted species by a method that contaminated the entire environment and brought the threat of disease and death even to their own kind?

Mankind has gone very far into an artificial world of his own creation. He has sought to insulate himself, in his cities of steel and concrete, from the realities of earth and water and the growing seed. Intoxicated with a sense of his own power, he seems to be going farther and farther into more experiments for the destruction of himself and his world. There is certainly no single remedy for this condition and I am offering no panacea. But it seems reasonable to believe — and I do believe — that the more clearly we can focus our attention on the wonders and realities of the universe about us the less taste we shall have for the destruction of our race. Wonder and humility are wholesome emotions, and they do not exist side by side with a lust for destruction.
