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

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

The forgotten world is made up primarily of the developing nations, where most of the people, comprising more than fifty percent of the total world population, live in poverty, with hunger as a constant companion and fear of famine a continual menace.

Contrasting sharply, in the developing countries represented by India, Pakistan, and most of the countries in Asia and Africa, seventy to eighty percent of the population is engaged in agriculture, mostly at the subsistence level.

Therefore I feel that the aforementioned guiding principle must be modified to read: If you desire peace, cultivate justice, but at the same time cultivate the fields to produce more bread otherwise there will be no peace.

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.

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

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.

Civilization as it is known today could not have evolved, nor can it survive, without an adequate food supply.

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

There are 6.6 billion people on the planet today. With organic farming we could only feed four billion of them. Which two billion would volunteer to die?

During the past three years spectacular progress has been made in increasing wheat, rice, and maize production in several of the most populous developing countries of southern Asia, where widespread famine appeared inevitable only five years ago

Man's survival, from the time of Adam and Eve until the invention of agriculture, must have been precarious because of his inability to ensure his food supply.

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

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

Man seems to insist on ignoring the lessons available from history.

The green revolution has an entirely different meaning to most people in the affluent nations of the privileged world than to those in the developing nations of the forgotten world.
