Corn is seen at the Phytogenetic Resources Center of the International Maize and Wheat Improvement Center, in Texcoco, Mexico, on October 28, 2009.
Earlier this month, a federal judge in Mexico issued a ban on growing genetically modified corn.
The decision came in response to a lawsuit filed last year by activists. They claim that the genetically modified corn would ruin Mexico's diverse corn crop by homogenizing it. But advocates say that the GMO corn is necessary for Mexico to feed its citizens.
Erick de la Barrera, a professor and an ecologist for the Scientific Advisory Council of the GMO Biosafety Comission in Mexico, joins the show with more.
