For decades, Monsanto has enjoyed unrivaled dominance in the pesticide and biotech seed marketplace. However, in recent years, the company’s monopoly control of agricultural seeds and pesticides — built largely on the marketing of its genetically engineered Roundup Ready seeds designed to maintain sale of its flagship herbicide Roundup — has begun to crack. Farmers have been struggling with the emergence and spread of RoundUp-resistant “superweeds” now infesting over 90 million acres of farmland. RoundUp has been found in nearly all stream and air samples tested in the Midwest. And the World Health Organization has concluded that glyphosate — the active ingredient in Roundup — is a probable carcinogen.Rather than clean up its act, Monsanto has redoubled its efforts to follow the same recipe for disaster, racing against rivals like Dow AgroScience to introduce new lines of transgenic seeds engineered to resist even more chemical herbicides.
