The ultimate work of energy production is accomplished not in any specialized organ but in every cell of the body. A living cell, like a flame, burns fuel to produce the energy on which life depends. The analogy is more poetic than precise, for the cell accomplishes its ‘burning’ with only the moderate heat of the body’s normal temperature. Yet all these billions of gently burning little fires spark the energy of life. Should they cease to burn, ‘no heart could beat, no plant could grow upward defying gravity, no amoeba could swim, no sensation could speed along a nerve, no thought could flash in the human brain,’ said the chemist Eugene Rabinowitch.

If the crisis that now confronts us is even more urgent than those of the early years of the century-and I believe it is this is because of wholly new factors peculiar to our own time. These are, first of all, the phenomenal growth of the human population, threatening to over-run its own environment in a way that can bring only deep concern to thoughtful students of population problems. The second factor is a corollary of the first: that as people and their demands increase, there is a smaller share of the earth's resources for each of us to use and enjoy. There is less clean water, less uncontaminated air; there are fewer forests, fewer unspoiled wilderness areas. The third reason is the introduction of new and dangerous contaminants into soil, water, air, and the bodies of plants and animals as our new technology spreads its poisons and its discarded wastes over the land.

If we have been slow to develop the general concepts of ecology and conservation, we have been even more tardy in recognizing the facts of the ecology and conservation of man himself. We may hope that this will be the next major phase in the development of biology. 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.

It was clear to the industry that Rachel Carson was a hysterical woman whose alarming view of the future could be ignored or, if necessary, suppressed. She was a “bird and bunny lover,” a woman who kept cats and was therefore clearly suspect.

There is one quality that characterizes all of us who deal with the sciences of the earth and its life-we are never bored. We can't be. There is always something new to be investigated. Every mystery solved brings us to the threshold of a greater one...

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 naive. In unlocking the secrets of the atom, modern man has found himself confronted with a frightening problem-what to do with the most dangerous materials that have ever existed in all the earth's history, the by-products of atomic fission. The stark problem that faces him is whether he can dispose of these lethal substances without rendering the earth uninhabitable. No account of the sea today is complete unless it takes note of this ominous problem. By its very vastness and its seeming remoteness, the sea has invited the attention of those who have the problem of disposal, and with very little discussion and almost no public notice, at least until the late 'fifties, the sea has been selected as a "natural" burying place for the contaminated rubbish and other "low-level wastes" of the Atomic Age.

Hearing the rising tide, I think how it is pressing also against other shores I know — rising on a southern beach where there is no fog, but a moon edging all the waves with silver and touching the wet sands with lambent sheen, and on a still more distant shore sending its streaming currents against the moonlit pinnacles and the dark caves of the coral rock.

Then in my thoughts these shores, so different in their nature and in the inhabitants they support, are made one by the unifying touch of the sea. For the differences I sense in this particular instant of time that is mine are but the differences of a moment, determined by our place in the stream of time and in the long rhythms of the sea. Once this rocky coast beneath me was a plain of sand; then the sea rose and found a new shore line. And again in some shadowy future the surf will have ground these rocks to sand and will have returned the coast to its earlier state. And so in my mind’s eye these coastal forms merge and blend in a shifting, kaleidoscopic pattern in which there is no finality, no ultimate and fixed reality — earth becoming fluid as the sea itself.

The chemicals to which life is asked to make its adjustment are no longer merely the calcium and silica and copper and all the rest of the minerals washed out of the rocks and carried in rivers to the sea; they are the synthetic creations of man’s inventive mind, brewed in his laboratories, and having no counterparts in nature.

"For most of us, knowledge of our world comes largely through sight, yet we look about with such unseeing eyes that we are partially blind. One way to open your eyes to unnoticed beauty is to ask yourself, "What if I had never seen this before? What if I knew I would never see it again?

The sharpest peaks of the Ridge are the cluster of islets known as the Rocks of St. Paul, near the equator. The entire cluster of half a dozen islets is not more than a quarter of a mile across, and their rocky slopes drop off at so sheer an angle that water more than half a mile deep lies only a few feet off shore.

To get the feeling of what it is like to be a creature of the sea requires the active exercise of the imagination and the temporary abandonment of many human concepts and human yardsticks. For example, time measured by the clock or the calendar means nothing if you are a shore bird or a fish, but the succession of light and darkness and the ebb and the flow of the tides mean the difference between the time to eat and the time to fast, between the time an enemy can find you easily and the time you are relatively safe. We cannot get the full flavor of marine life — cannot project ourselves vicariously into it — unless we make these adjustments in our thinking.

It is not my contention that chemical insecticides must never be used. I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these poisons, without their consent and often without their knowledge.
