The biggest obstacle was mixing abortion with overpopulation. These are two things that have nothing to do with each other.
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.
Farming as we do it is hunting, and in the sea we act like barbarians.
The happiness of the bee and the dolphin is to exist. For man it is to know that and to wonder at it.
From birth, man carries the weight of gravity on his shoulders. He is bolted to earth. But man has only to sink beneath the surface and he is free.
If we were logical, the future would be bleak, indeed. But we are more than logical. We are human beings, and we have faith, and we have hope, and we can work.
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.

The sea, once it casts its spell, holds one in its net of wonder forever.
It takes generosity to discover the whole through others. If you realize you are only a violin, you can open yourself up to the world by playing your role in the concert.
The real cure for our environmental problems is to understand that our job is to salvage Mother Nature. We are facing a formidable enemy in this field. It is the hunters... and to convince them to leave their guns on the wall is going to be very difficult.
We forget that the water cycle and the life cycle are one.
Mankind has probably done more damage to the Earth in the 20th century than in all of previous human history.
Man, of all the animals, is probably the only one to regard himself as a great delicacy.
If we go on the way we have, the fault is our greed and if we are not willing to change, we will disappear from the face of the globe, to be replaced by the insect.
No aquarium, no tank in a marine land, however spacious it may be, can begin to duplicate the conditions of the sea. And no dolphin who inhabits one of those aquariums or one of those marine lands can be considered normal.
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.
However fragmented the world, however intense the national rivalries, it is an inexorable fact that we become more interdependent every day.
It is certain that the study of human psychology, if it were undertaken exclusively in prisons, would also lead to misrepresentation and absurd generalizations.
I believe that national sovereignties will shrink in the face of universal interdependence.
