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.)

The road to the future leads us smack into the wall. We simply ricochet off the alternatives that destiny offers. Our survival is no more than a question of 25, 50 or perhaps 100 years.

I wake up saying, I'm still alive; a miracle. And so I keep on pushing.

We have to prepare for what life could become in 40 years. We need to outline what is possible and what is impossible with the non-renewable resources of the Earth. What role will technological improvement play? Taking all this into account, what kind of life can we produce in the best way for 10 billion people? That's a problem that needs to be solved.

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

How dangerous are those sea animals with bad reputations? A few actually kill. A few maim. Some are poisonous when eaten by man. Most sting, stab,or poison and cause mild to severe discomfort to man. Yet man is one of the larger beings that sea creatures encounter, and these poisons usually can't kill him.

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.
