Since its introduction of genetically modified crops, Monsanto has generated a sea of controversy among small farmers across the U.S., and the company is now trying to expand south into Mexico. After years of trying to penetrate the Mexican market, Monsanto, Dupont, and Dow had a breakthrough when outgoing Mexican president Felipe Calderón granted them the right to cultivate GMO corn in various northern Mexican states. Protesting the influx of genetically modified crops in their country, activists, farmers, and academics all across Mexico have been mobilizing to urge the new Mexican president Enrique Peña Nieto to reject these permissions.
