William

“We need the tonic of wildness...At the same time that we are earnest to explore and learn all things, we require that all things be mysterious and unexplorable, that land and sea be indefinitely wild, unsurveyed and unfathomed by us because unfathomable. We can never have enough of nature.”
― Henry David Thoreau, Walden: Or, Life in the Woods

“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.”
― Wallace Stegner, The Sound of Mountain Water

“I am glad I will not be young in a future without wilderness.”
― Aldo Leopold

“The poetry of the earth is never dead.”
― John Keats
