I have already set my DVR to record tonight’s episode of “American Experience” on PBS, which profiles a scientific hero, Norman Borlaug. He was an American agronomist who won the 1970 Nobel Peace Prize for his efforts in fighting global hunger by increasing the world’s food supply. Borlaug rescued India from a severe famine, saved a billion lives in the process, and was dubbed The Father Of The Green Revolution. But there were consequences, as you’ll see in the hour-long documentary.
