Plant diseases, drought, desolation, despair were recurrent catastrophes during the ages - and the ancient remedies: supplications to supernatural spirits or gods.

You can't build a peaceful world on empty stomachs and human misery.

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

Almost certainly, the first essential component of social justice is adequate food for all mankind. Food is the moral right of all who are born into this world. Yet today 50 percent of the world’s population goes hungry. Without food, man can live at most but a few weeks; without it, all other components of social justice are meaningless.

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.

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

There can be no permanent progress in the battle against hunger until the agencies that fight for increased food production and those that fight for population control unite in a common effort.
