“Something will have gone out of us as a people if we ever let the remaining wilderness be destroyed ... We simply need that wild country available to us, even if we never do more than drive to its edge and look in.”

“We have no means of understanding a fraction of the thought and science and philosophy and law that have gone to make that outside world. We simply accept it. We have grown up paying tribute to it, and that is all the most of us can do. We feel of the great world that it is simply there, something for the lucky ones to explore, and then only at the edges. It never occurs to us that we might make some contribution to it ourselves. And that is why we miss everything.”

“How can we be so arrogant? The planet is, was, and always will be stronger than us. We can't destroy it; if we overstep the mark, the planet will simply erase us from its surface and carry on existing. Why don't they start talking about not letting the planet destroy us?”

“The love of wilderness is more than a hunger for what is always beyond reach; it is also an expression of loyalty to the earth, the earth which bore us and sustains us, the only paradise we shall ever know, the only paradise we ever need, if only we had the eyes to see.”

“A man could be a lover and defender of the wilderness without ever in his lifetime leaving the boundaries of asphalt, powerlines, and right-angled surfaces. We need wilderness whether or not we ever set foot in it. We need a refuge even though we may never need to set foot in it. We need the possibility of escape as surely as we need hope; without it the life of the cities would drive all men into crime or drugs or psychoanalysis.”

“I suspect there will never be a requiem for a dream, simply because it will destroy us before we have the opportunity to mourn it's passing.”
