The continued existence of wildlife and wilderness is important to the quality of life of humans.
What we are doing to the forests of the world is but a mirror reflection of what we are doing to ourselves and to one another.
The human spirit needs places where nature has not been rearranged by the hand of man.
We won't save places we don't love; we can't love places we don't know; and we can't know places we haven't learned.
The wildlife of today is not ours to dispose of as we please. We have it in trust. We must account for it to those who come after.
In the end, we will conserve only what we love; we will love only what we understand, and we will understand only what we are taught.
A true conservationist is a man who knows that the world is not given by his fathers but borrowed from his children.
The greatness of a nation and its moral progress can be judged by the way its animals are treated.
