When a man must be afraid to drink freely from his country's river and streams that country is no longer fit to live in. - Edward Abbey

The plow has probably done more harm — in the long run — than the sword.

I hold no preference among flowers, so long as they are wild, free, spontaneous. (Bricks to all greenhouses! Black thumb and cutworm to the potted plant!)

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.
