"But love of the wilderness is more than a hunger for what is always beyond reach; it is also an expression of loyalty to the earth which bore us and sustains us, the only home we shall ever know, the only paradise we ever need - if only we had eyes to see."
"I come more and more to the conclusion that wilderness, in America or anywhere else, is the only thing left that is worth saving."
"The idea of wilderness needs no defense. It only needs more defenders."
"Wilderness is not a luxury but a necessity of the human spirit."
