Rachel Carson

Water, soil, and the earth’s green mantle of plants make up the world that supports the animal life of the earth. Although modern man seldom remembers the fact, he could not exist without the plants that harness the sun’s energy and manufacture the basic foodstuffs he depends upon for life. Our attitude toward plants is a singularly narrow one. If we see any immediate utility in a plant, we foster it. If, for any reason, we find its presence undesirable, or even simply a matter of indifference, we may condemn it to destruction forthwith. Besides the various plants that are poisonous to man or his livestock, or crowd out food plants, many are marked for destruction merely because they happen to be in the wrong place at the wrong time, and many others are destroyed merely because they happen to be associates of the unwanted plants. Sometimes we have no choice but to disturb the relationships between plants and the earth, between plants and other plants, and between plants and animals, yet we should do so thoughtfully, with full awareness that what we do may have consequences remote in time and place.
