Perhaps most ridiculous of all is the suggestion that we 'keep' our radioactive garbage for the use of our descendants. This 'solution', I think, requires an immediate poll of the next 20,000 generations.

The Sierra Club is a very good and a very powerful force for conservation and, as a matter of fact, has grown faster since I left than it was growing while I was there! It must be doing something right.

Polite conservationists leave no mark save the scars upon the Earth that could have been prevented had they stood their ground.

It is absolutely imperative that we protect, preserve and pass on this genetic heritage for man and every other living thing in as good a condition as we received it.

Truth and beauty can still win battles. We need more art, more passion, more wit in defense of the Earth.
