I like to define biology as the history of the earth and all its life – past, present, and future.
For mankind as a whole, a possession infinitely more valuable than individual life is our genetic heritage, our link with past and future.
The ultimate answer is to use less toxic chemicals so that the public hazard from their misuse is greatly reduced.
For time is the essential ingredient; but in the modern world there is no time. The rapidity of change and the speed with which new situations are created follow the impetuous and heedless pace of man rather than the deliberate pace of nature.
What if I had never seen this before? What if I knew I would never see it again?
Between low water and the flotsam and jetsam of the high-tide mark, land and sea wage a never-ending conflict for possession.
The sediments are a sort of epic poem of the earth.
Whatever the vexations or concerns of their personal lives, their thoughts can find paths that lead to inner contentment and to renewed excitement in living. Those who contemplate the beauty of the earth find reserves of strength that will endure as long as life lasts. There is symbolic as well as actual beauty in the migration of the birds, the ebb and flow of the tides, the folded bud ready for the spring.
We stand now where two roads diverge. But unlike the roads in Robert Frost’s familiar poem, they are not equally fair. The road we have long been traveling is deceptively easy, a smooth superhighway on which we progress with great speed, but at its end lies disaster. The other fork of the road – the one less traveled by – offers our last, our only chance to reach a destination that assures the preservation of the earth.
If I had influence with the good fairy who is supposed to preside over the christening of all children, I should ask that her gift to each child in the world be a sense of wonder so indestructible that it would last throughout life, as an unfailing antidote against the boredom and disenchantments of later years, the sterile preoccupation with things that are artificial, the alienation from the sources of our strength.
Such plants are “weeds” only to those who make a business of selling and applying chemicals.
Given time – time not in years but in millennia – life adjusts, and a balance has been reached. For time is the essential ingredient; but in the modern world there is no time.
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.
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.
They should not be called ‘insecticides’, but ‘biocides’.
And as life began in the sea, so each of us begins his identical life in a miniature ocean within his mother’s womb.
The question of chemical residues on the food we eat is a hotly debated issue. The existence of such residues is either played down by the industry as unimportant or is flatly denied. Simultaneously, there is a strong tendency to brand as fanatics or cultists all who are so perverse as to demand that their food be free of insect poisons. In all this cloud of controversy, what are the actual facts?
It is only within the moment of time represented by the twentieth century that one species – man – has acquired significant power to alter the nature of his world, and it is only within the past twenty-five years that his power has achieved such magnitude that it endangers the whole earth and its life. The most alarming of all man’s assaults upon the environment is the contamination of the air, earth, rivers, and seas with dangerous, and even lethal, materials.
The same thing happens in other situations. A generation or more ago, the towns of large areas of the United States lined their streets with the noble elm tree. Now the beauty they hopefully created is threatened with complete destruction as disease sweeps through the elms, carried by a beetle that would have only limited chance to build up large populations and to spread from tree to tree if the elms were only occasional trees in a richly diversified planting.
It soon became evident that there was no single animal – bird, fish, mammal, or any of the sea’s lesser creatures – that could live in all the various parts of the sea I proposed to describe. That problem was instantly solved, however, when I realised that the sea itself must be the central character whether I wished it or not; for the sense of the sea, holding the power of life and death over every one of its creatures from the smallest to the largest, would inevitably pervade every page.
If we would divert to constructive research even a small fraction of the money spent each year on the development of ever more toxic sprays, we could find ways to use less dangerous materials and to keep poisons out of our waterways. When will the public become sufficiently aware of the facts to demand such action?
