What is such a resource worth? Anything it costs. If we never hike it or step into its shade, if we only drive by occasionally and see the textures of green mountainside change under wind and sun, or the fog move soft feathers down the gulches, or the last sunset on the continent redden the sky beyond the ridge, we have our money's worth. We have been too efficient at destruction; we have left our souls too little space to breathe in. Every green natural place we save saves a fragment of our sanity and gives us a little more hope that we have a future.

If the national park is, as Lord Bryce suggested, the best idea America has ever had, wilderness preservation is the highest refinement of that idea.

We need wilderness preserved-as much of it as is still left, and as many kinds-because it was the challenge against which our character as a people was formed.

Something will have gone out of us as a people if we ever let the remaining wilderness be destroyed; if we permit the last virgin forests to be turned into comic books and plastic cigarette cases; if we drive the few remaining members of the wild species into zoos or to extinction; if we pollute the last clear air and dirty the last clean streams and push our paved roads through the last of the silence . . .

Be proud of every scar on your heart, each one holds a lifetime’s worth of lessons.

But however you might rebel, there was no shedding them. They were your responsibility and there was no one to relieve you of them. They called you Sis. All your life people called you Sis, because that was what you were, or what you became - big sister, helpful sister, the one upon whom everyone depended, the one they all came to for everything from help with homework to a sliver under the fingernail.

It should not be denied... that being footloose has always exhilarated us. It is associated in our minds with escape from history and oppression and law and irksome obligations, with absolute freedom, and the road has always led West.
