Expose a child to a particular environment at this susceptible time and he will perceive in the shapes of that environment until he dies.

If you're going to get old, you might as well get as old as you can get.

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.
