No more cars in national parks. Let the people walk. Or ride horses, bicycles, mules, wild pigs — anything — but keep the automobiles and the motorcy… - Edward Abbey

It seems to me possible, even probable, that many of the nonhuman undomesticated animals experience emotions unknown to us. What do the coyotes mean when they yodel at the moon? What are the dolphins trying so patiently to tell us? Precisely what did those two enraptured gopher snakes have in mind when they came gliding toward my eyes over the naked sandstone?

Suppose we say that wilderness invokes nostalgia, a justified not merely sentimental nostalgia for the lost America our forefathers knew. The word suggests the past and the unknown, the womb of earth from which we all emerged. It means something lost and something still present, something remote and at the same time intimate, something buried in our blood and nerves, something beyond us and without limit. Romance — but not to be dismissed on that account. The romantic view, while not the whole of truth, is a necessary part of the whole truth. 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.
