Norman Borlaug
Nobel Prize winning agronomist
"This year the Nobel Committee of the Norwegian Parliament has awarded Nobel's Peace Prize to a scientist, Dr. Norman Ernest Borlaug, because, more than any other single person of this age, he has helped to provide bread for a hungry world. We have made this choice in the hope that providing bread will also give the world peace."

On Organic Farming
Ronald Bailey (interviewer): What do you think of organic farming? A lot of people claim it's better for human health and the environment.
Norman Borlaug: That�s ridiculous. This shouldn�t even be a debate. Even if you could use all the organic material that you have � the animal manures, the human waste, the plant residues � and get them back on the soil, you couldn�t feed more than 4 billion people. In addition, if all agriculture were organic, you would have to increase cropland area dramatically, spreading out into marginal areas and cutting down millions of acres of forests.
At the present time, approximately 80 million tons of nitrogen nutrients are utilized each year. If you tried to produce this nitrogen organically, you would require an additional 5 or 6 billion head of cattle to supply the manure. How much wild land would you have to sacrifice just to produce the forage for these cows? There�s a lot of nonsense going on here.
If people want to believe that the organic food has better nutritive value, it�s up to them to make that foolish decision. But there�s absolutely no research that shows that organic foods provide better nutrition. As far as plants are concerned, they can�t tell whether that nitrate ion comes from artificial chemicals or from decomposed organic matter.
If some consumers believe that it�s better from the point of view of their health to have organic food, God bless them. Let them buy it. Let them pay a bit more. It�s a free society. But don�t tell the world that we can feed the present population without chemical fertilizer. That�s when this misinformation becomes destructive.
