For most of history, man has had to fight nature to survive; in this century he is beginning to realize that, in order to survive, he must protect it.

We are human beings, and we have faith, and we have hope

It is certain that the study of human psychology, if it were undertaken exclusively in prisons, would also lead to misrepresentation and absurd generalizations.

Perhaps the time has come to formulate a moral code which would govern our relations with the great creatures of the sea as well as with those on dry land. That this will come to pass is my dear wish.

If human civilization is going to invade the waters of the earth, then let it be first of all to carry a message of respect.

The reason I love the sea I cannot explain - it's physical. When you dive you begin to feel like an angel. It's a liberation of your weight.

It's terrible to have to say this. World population must be stabilized and to do that we must eliminate 350,000 people per day. This is so horrible to contemplate that we shouldn't even say it. But the general situation in which we are involved is lamentable.
