The awareness of our environment came progressively in all countries with different outlets.

When one man, for whatever reason, has the opportunity to lead an extraordinary life, he has no right to keep it to himself.

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

All life is part of a complex relationship in which each is dependent upon the others, taking from, giving to and living with all the rest.

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.

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.

If we go on the way we have, the fault is our greed and if we are not willing to change, we will disappear from the face of the globe, to be replaced by the insect.
