In the lowest pools the Laminarias begin to appear, called variously the oarweeds, devil’s aprons, sea tangles, and kelps. The Laminarias belong to the brown algae, which flourish in the dimness of deep waters and polar seas. The horsetail kelp lives below the tidal zone with others of the group, but in deep pools also comes over the threshold, just above the line of the lowest tides. [...] To look into such a pool is to behold a dark forest, it’s foliage like the leaves of palm trees, the heavy stalks of the kelps also curiously like the trunks of palms. [...] One of these laminarian holdfasts is something like the roots of a forest tree, branching out, dividing, subdividing, in its very complexity a measure of the great seas that roar over this plant.

facts are the seeds that later produce knowledge and wisdom, then the emotions and the impressions of the senses are the fertile soil in which the seeds must grow. The years of early childhood are the time to prepare the soil.

All this has come about because of the sudden rise and prodigious growth of an industry for the production of man-made or synthetic chemicals with insecticidal properties. This industry is a child of the Second World War. In the course of developing agents of chemical warfare, some of the chemicals created in the laboratory were found to be lethal to insects. The discovery did not come by chance: insects were widely used to test chemicals as agents of death for man.

Those who contemplate the beauty of the earth find reserves of strength that will endure as long as life lasts. There is something infinitely healing in the repeated refrains of nature - the assurance that dawn comes after night, and spring after winter.

"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."

We must change our philosophy, abandon our attitude of human superiority and admit that in many cases in natural environments we find ways and means of limiting populations of organisms in a more economical way than we can do it ourselves

Most of us walk unseeing through the world, unaware alike of its beauties, its wonders, and the strange and sometimes terrible intensity of the lives that are being lived about us.

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.

[…] can we afford to ignore the fact that we are now filling the environment with chemicals that have the power to strike directly at the chromosomes […]? Is this not too high a price to pay for a sproutless potato or a mosquitoless patio?

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...

we live in a time when change comes rapidly-a time when much of that change is, at least for long periods, irrevocable. This is what makes our own task so urgent. It is not often that a generation is challenged, as we today are challenged. For what we fail to do-what we let go by default, can perhaps never be done.
