Corn is a part of modern life in all sorts of ways: It fattens up livestock and gets turned into biofuels. We eat it on the cob, as grits, polenta and tortillas, and as syrup that sweetens so many other foods.Most of the corn used in the U.S. is sprayed with weed killers such as glyphosate and is genetically modified to survive those weed killers and to create bigger yields — controversial practices.Mexico, corn’s birthplace, imports millions of tons of U.S. corn each year. But there’s about to be a dramatic change. The nation is preparing to shut its doors to GMO corn and ban glyphosate. Today we talk with reporter Renée Alexander, as well as the head of a company that’s devoted to buying from Mexican farmers who grow non-GMO corn, about what that means for both Mexico and the United States.Host: Gustavo ArellanoGuests: Journalist Renée Alexander and Masienda founder and CEO Jorge GaviriaMore reading:Mexico is phasing out imports of glyphosate and GMO cornChampion of poor or demagogue?
