And let us remember too that life, in its exuberance, always succeeds in overflowing the narrow limits within which man thinks he can confine it.

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.

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.

Buoyed by water, he can fly in any direction - up, down, sideways - by merely flipping his hand. Under water, man becomes an archangel.

Farming as we do it is hunting, and in the sea we act like barbarians.

When we return wild animals to nature, we merely return them to what is already theirs. For man cannot give wild animals freedom, they can only take it away.

We have to prepare for what life could become in 40 years. We need to outline what is possible and what is impossible with the non-renewable resources of the Earth. What role will technological improvement play? Taking all this into account, what kind of life can we produce in the best way for 10 billion people? That's a problem that needs to be solved.
