All living things on earth are kindred. — Edward Abbey

But 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 home we shall ever know, the only paradise we ever need — if only we had the eyes to see. Original sin, the true original sin, is the blind destruction for the sake of greed of this natural paradise which lies all around us — if only we were worthy of it.

Balance, that's the secret. Moderate extremism.

Wilderness is not a luxury but a necessity of the human spirit, and as vital to our lives as water and good bread. A civilization which destroys what little remains of the wild, the spare, the original, is cutting itself off from its origins and betraying the principle of civilization itself.
