Roundup’s active ingredient, glyphosate, is widely perceived to be innocuous in the environment because it targets an enzyme not found in animals or humans. When it comes to plants, however, the chemical kills indiscriminately—except for those plants genetically designed to withstand it. In the 1990s, Monsanto began to sell its patented “Roundup Ready” seeds, allowing farmers to spray for weeds without damaging their crops. The combination of herbicide and resistant seeds helped Monsanto become one of the world’s most powerful agriculture corporations. Today, over 90 percent of domestic soy, corn, and cotton crops are genetically engineered to be glyphosate-resistant, accounting for more than 168 million acres.
But the future of the ubiquitous herbicide is in question. Monsanto is currently fighting allegations that glyphosate might not be as safe as advertised, particularly when combined with other chemicals in Roundup. In 2015, an international science committee ruled that glyphosate is a probable human carcinogen, countering previous determinations by regulatory agencies in the United States and other countries. Soon after, more than 200 people sued Monsanto in a federal case now centralized in California, claiming that Roundup caused them to develop non-Hodgkin’s lymphoma, a common blood cancer. Over 1,000 people have filed similar suits against the company in state courts in Arizona, Delaware, Missouri, Nebraska, and elsewhere.
