Destroying rainforest for economic gain is like burning a Renaissance painting to cook a meal.

I think it is far more important to save one square mile of wilderness, anywhere, by any means, than to produce another book on the subject.

Devoted though we must be to the conservation cause, I do not believe that any of us should give it all of our time or effort or heart. Give what you can, but do not burn yourselves out -- or break your hearts. Let us save at least half of our lives for the enjoyment of this wonderful world which still exists. Leave your dens, abandon your cars and walk out into the great mountains, the deserts, the forests, the seashores. Those treasures still belong to all of us. Enjoy them to the full, stretch your legs, expand your lungs, enliven your hearts -- and we will outlive the greedy swine who want to destroy it all in the name of what they call GROWTH.
God bless America -- let's save some of it.
Long live the weeds and the wilderness yet!

This sweet virginal primitive land will metaphorically breathe a sigh of relief --like a whisper of wind--when we are all and finally gone and the place and its creations can return to their ancient procedures unobserved and undisturbed by the busy, anxious, brooding consciousness of man.

It is not easy to make a simile go on all-fours.

I don't flatter myself - I'm not a scientist, I'm not a conservation expert.
