The best way to observe a fish is to become a fish.

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

It is fashionable nowadays to talk about the endless riches of the sea. The ocean is regarded as a sort of bargain basement, but I don't agree with that estimate. People don't realize that water in the liquid state is very rare in the universe. Away from earth it is usually a gas. This moisture is a blessed treasure, and it is our basic duty, if we don't want to commit suicide, to preserve it.

We forget that the water cycle and the life cycle are one.

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

However fragmented the world, however intense the national rivalries, it is an inexorable fact that we become more interdependent every day.
