[…] 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… - Rachel Carson

Man has long talked somewhat arrogantly about the conquest of nature; now he has the power to achieve his boast. It is our misfortune-it may well be our final tragedy-that this power has not been tempered with wisdom, but has been marked by irresponsibility; that there is all too little awareness that man is part of nature, and that the price of conquest may well be the destruction of man himself.

For we all are united in a common cause. It is a proud cause, which we may serve secure in the knowledge that the earth will be better for our efforts. It is a cause that has no end: there is no point at which we shall say, "Our work is finished." We build on the achievements of those who have gone before us; let us, in turn, build strong foundations for those who will take up the work when we must lay it down.

Man's attitude toward nature is today critically important, simply because of his new-found power to destroy it.
