All life is part of a complex relationship in which each is dependent upon the others, taking from, giving to and living with all the rest.

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 know how to organize warfare, but do we know how to act when confronted with peace?

There are no boundaries in the real Planet Earth. No United States, no Soviet Union, no China, no Taiwan...Rivers flow unimpeded across the swaths of continents. The persistent tides - the pulse of the sea - do not discriminate; they push against all the varied shores on Earth.

We must go and see for ourselves.

To restate an old law - when a man bites a fish, that's good, but when a fish bites a man, that's bad. This is one way of saying it's all right if man kills an animal, but if an animal attacks man, the act is reprehensible.

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.)
