1. There are now more obese people than starving people in the world. The diseases that are killing those overweight people are largely nutritional in origin (heart disease, diabetes, at least some cancers).
2. The EU (and I assume the US/Canada as well) are destroying agricultural products en masse, due to subsidized overproduction.
3. Population growth is rapidly decelerating - the largest countries in the world have or are rapidly approaching "first world" birth rates. Western Europe is shrinking.
Borlaug did phenomenal work for his historical period, however, looking at it in a historical timeframe, we should remain aware that the parameters of our world are constantly changing, and thus it's not that simple.
Personally, I think it requires a careful look at the political and economic production and distribution systems around the agriculture and food industries. The whole "granola hippie" versus "libertarian corporatist" debate is simply a huge distraction that misses the point.
