Joy in looking and comprehending is nature's most beautiful gift.

Human subtlety will never devise an invention more beautiful, more simple or more direct than does nature because in her inventions nothing is lacking, and nothing is superfluous.

I see an America whose rivers and valleys and lakes hills and streams and plains the mountains over our land and nature's wealth deep under the earth are protected as the rightful heritage of all the people.

A forest is not solely so many thousand board feet of lumber to be logged when market conditions make it profitable. It is an integral part of our natural land covering, and the most potent factor in maintaining Nature's delicate balance in the organic and inorganic worlds.

In his struggle for selfish gain, man has often needlessly tipped the scales so that Nature's balance has been destroyed, and the public welfare has usually been on the short-weighted side. Such public necessities, therefore, must not be destroyed because there is profit for someone in their destruction.

What a book a devil's chaplain might write on the clumsy, wasteful, blundering, low, and horribly cruel work of nature!
