A lot of the GMO fetishists are completely ignorant of the Green Revolution and how the economics of modern industrial food have contributed to hunger. Industrial agriculture for cash crops brings in global money, topples governments, and arms the police to run traditional agriculture off the lands that once fed the people. Third world shantytowns are filled with people who were once farmers, before "modern" agriculture was introduced to the land they once farmed.

GMO is just an extension of Green Revolution capitalism-centric agriculture. That model has done miracles for supporting the growing population and making food cheaper, but it's not a free lunch.
