It seems that every time mankind is given a lot of energy, we go out and wreck something with it.

There is no place where we can safely store worn-out reactors or their garbage. No place!

You don't need it, but will you take some advice from a Californian who's been around for a while? Cherish these rivers. Witness for them. Enjoy their unimprovable purpose as you sense it, and let those rivers that you never visit comfort you with the assurance that they are there, doing wonderfully what they have always done.

Keep your rivers flowing as they will, and you will continue to know the most important of all freedoms-the boundless scope of the human mind to contemplate wonders, and to begin to understand their meaning.
