However fragmented the world, however intense the national rivalries, it is an inexorable fact that we become more interdependent every day.

Mankind has probably done more damage to the Earth in the 20th century than in all of previous human history.

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.

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.

With earth's burgeoning human population to feed we must turn to the sea with understanding and new technology. We need to farm it as we farm the land.

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.

The future is in the hands of those who explore... and from all the beauty they discover while crossing perpetually receding frontiers, they develop for nature and for humankind an infinite love.
