We must go and see for ourselves.

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.

I wake up saying, I'm still alive; a miracle. And so I keep on pushing.

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 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.

Overconsumption and overpopulation underlie every environmental problem we face today

However fragmented the world, however intense the national rivalries, it is an inexorable fact that we become more interdependent every day. I believe that national sovereignties will shrink in the face of universal interdependence. 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.
