There have been many obituaries written in the last week for the great scientist, Norman Borlaug, who according to some estimates saved the lives of 1 billion people. By developing new strains of crops that were resistant to disease and teaching poor third world farmers modern agriculture techniques, Mr. Borlaug was a big part of the massive increase in food supply in the world, especially the poorest regions. What is also more interesting is that it is highly unlikely that Asia would have had its economic miracle without such massive increases in the availability of food and improvement of nutrition.
Here are two obituaries that I really liked. I recommend that you read both, just so you can get an impact for how great of a man Mr. Borlaug was.
