Our society is turning toward more and more needless consumption. It is a vicious circle that I compare to cancer . . . . Should we eliminate suffering, diseases? The idea is beautiful, but perhaps not a benefit for the long term. We should not allow our dread of diseases to endanger the future of our species. . . . In order to stabilize world population, we need to eliminate 350,000 people a day. It is a horrible thing to say, but it's just as bad not to say it.

If human civilization is going to invade the waters of the earth, then let it be first of all to carry a message of respect.

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.

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.

In the deep space of the sea I have found my moon

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.

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.
