Those who dwell, as scientists or laymen, among the beauties and mysteries of the earth, are never alone or weary of life. - Rachel Carson

But the stream of time moves forward and mankind moves with it. Your generation must come to terms with the environment. Your generation must face realities instead of taking refuge in ignorance and evasion of truth. Yours is a grave and a sobering responsibility, but it is also a shining opportunity.

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."
