The impossible missions are the only ones which succeed.

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 reason I love the sea I cannot explain - it's physical. When you dive you begin to feel like an angel. It's a liberation of your weight.

The best way to observe a fish is to become a fish.

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.

Perhaps the time has come to formulate a moral code which would govern our relations with the great creatures of the sea as well as with those on dry land. That this will come to pass is my dear wish.

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.
