No witchcraft, no enemy action had silenced the rebirth of new life in this stricken world. The people had done it themselves. - Rachel Carson

The sea is blue because the sunlight is reflected back to our eyes from the water molecules or from very minute particles suspended in the sea. In the journey of the light rays downward into the water and back to our eyes, all the red rays of the spectrum and most of the yellow have been absorbed, so it is chiefly the cool, blue light that we see.

As I look back through history I find a parallel. I ask you to recall the uproar that followed Charles Darwin's announcement of his theories of evolution. The concept of man's origin from pre-existing forms was hotly and emotionally denied, and the denials came not only from the lay public but from Darwin's peers in science. Only after many years did the concepts set forth in The Origin of Species become firmly established. Today, it would be hard to find any person of education who would deny the facts of evolution. Yet so many of us deny the obvious corollary: that man is affected by the same environmental influences that control the lives of all the many thousands of other species to which he is related by evolutionary ties.

Through all these new, imaginative, and creative approaches to the problem of sharing our earth with other creatures there runs a constant theme, the awareness that we are dealing with life-with living populations and all their pressures and counter-pressures, their surges and recessions. Only by taking account of such life forces and by cautiously seeking to guide them into channels favorable to ourselves can we hope to achieve a reasonable accommodation between the insect hordes and ourselves. The current vogue for poisons has failed utterly to take into account these most fundamental considerations. As crude a weapon as the cave man's club, the chemical barrage has been hurled against the fabric of life-a fabric on the one hand delicate and destructible, on the other miraculously tough and resilient, and capable of striking back in unexpected ways. These extraordinary capacities of life have been ignored by the practitioners of chemical control who have brought to their task no "high-minded orientation," no humility before the vast forces with which they tamper.
