However fragmented the world, however intense the national rivalries, it is an inexorable fact that we become more interdependent every day. I believe that national sovereignties will shrink in the face of universal interdependence. The sea, the great unifier, is man's only hope. Now, as never before, the old phrase has a literal meaning: We are all in the same boat.

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.

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

I said that the oceans were sick but they're not going to die. There is no death possible in the oceans - there will always be life - but they're getting sicker every year.

There is about as much educational benefit to be gained in studying dolphins in captivity as there would be studying mankind by only observing prisoners held in solitary confinement.

It's terrible to have to say this. World population must be stabilized and to do that we must eliminate 350,000 people per day. This is so horrible to contemplate that we shouldn't even say it. But the general situation in which we are involved is lamentable.

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