The happiness of the bee and the dolphin is to exist. For man it is to know that and to wonder at it.

Man has only to sink beneath the surface and he is free.

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.

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.)

In order to stabilize world population, we must eliminate 350,000 per day.

Farming as we do it is hunting, and in the sea we act like barbarians.

There are a few animals that have won themselves a bad reputation even though they have little or no effect on man. They have won their rating through man's interpretation of their attitude towards lower animals. These animals have been seen feeding in what appears to be a savage manner. But this behavior may perhaps be comparable to a man tearing the flesh off a chicken leg with his teeth.
