The fourth largest crop in the United States is alfalfa, of which 5 percent is exported to Japan. RoundUp Ready alfalfa is genetically engineered to resist glyphosate, the active ingredient in the herbicide RoundUp. The U.S. Department of Agriculture (USDA) regulates genetically engineered agricultural products through the Animal and Plant Health Inspection Service (APHIS). APHIS concluded that RoundUp Ready alfalfa does not have any harmful health effects on humans or livestock and deregulated it. Geertson Seed Farms and others filed a suit in a federal district court against Mike Johanns (the secretary of the USDA) and others, asserting that APHIS’s decision required the preparation of an environmental impact statement (EIS). The plaintiffs argued, among other things, that the introduction of RoundUp Ready alfalfa might significantly decrease the availability of, or even eliminate, all nongenetically engineered varieties. The plaintiffs were concerned that the RoundUp Ready alfalfa might contaminate standard alfalfa because alfalfa is pollinated by bees, which can travel as far as two miles from a pollen source. If contamination occurred, farmers would not be able to market “contaminated” varieties as “organic,” which would impact the sales of “organic” livestock and exports to Japan, which does not allow the import of glyphosate-tolerant alfalfa. Should an EIS be prepared in this case? Why or why not?
