I swam across the rocks and compared myself favorably with the sars. To swim fishlike, horizontally, was the logical method in a medium eight hundred times denser than air. To halt and hang attached to nothing, no lines or air pipe to the surface, was a dream. At night I had often had visions of flying by extending my arms as wings. Now I flew without wings. (Since that first aqualung flight, I have never had a dream of flying.)

Overconsumption and overpopulation underlie every environmental problem we face today

We must plant the sea and herd its animals using the sea as farmers instead of hunters. That is what civilization is all about - farming replacing hunting.

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

When one man, for whatever reason, has the opportunity to lead an extraordinary life, he has no right to keep it to himself.

With earth's burgeoning human population to feed we must turn to the sea with understanding and new technology. We need to farm it as we farm the land.

And let us remember too that life, in its exuberance, always succeeds in overflowing the narrow limits within which man thinks he can confine it.
