When Columbus first arrived in the Americas, there were close to 300 varieties of corn being grown on the continent. Today, only 16 varieties of corn account for over 70% of the corn being grown in the United States. With the advent of genetically engineered corn, we are in danger of losing all genetic diversity, leaving the nations corn crop open to widespread destruction by a single fungus or disease.
