Food is the moral right of all who are born into this world.

This is a basic problem, to feed 6.6 billion people. Without fertilizer, forget it. The game is over.

Man can and must prevent the tragedy of famine in the future instead of merely trying with pious regret to salvage the human wreckage of the famine, as he has so often done in the past.

Without food, man at most can live but a few weeks; without it all other components of social justice are meaningless.

The destiny of world civilization depends upon providing a decent standard of living for all mankind.

We are 6.6 billion people now. We can only feed 4 billion. I don't see 2 billion volunteers to disappear.

To this day, I enjoy nature, the luxury of undisturbed wilderness, forests, mountains, lakes, rivers and deserts and their wildlife. But I also know that the greatest danger to their perpetuity is the pressure of human population.
