World food supply tightens
It is often said that Americans have been spoiled by an inexpensive and abundant food supply. The Green Revolution, which began in Mexico in the 1940s applied more sophisticated methods of crop development and turned countries like Mexico and India, which faced population starvation, into wheat and rice exporting countries; they have not faced starvation threats since that revolution took place. Similar improvements were achieved in the American farming system. The father of the Green Revolution was Norman Borlaug, a Minnesota Ph.D. graduate in Agriculture, who won the Nobel Peace Prize in 1970 for his seminal work in saving much of the world from the starvation threats created by population expansion and inefficient farming practices. Although his methods have been criticized for excessive use of chemicals and single crop farming methods, the impact of his work was dramatic in improving the crop yields/acre. India for example, which faced population starvation in the 1960s, adopted these methods and became (and still is) a net rice exporting country, by increasing its per acre yield of rice by 10 fold.
