History

Historical Context

After the EPA registered Monsanto’s glyphosate herbicide Roundup in 1974, the product’s use surged—a 100-fold rise worldwide by 2014 and spurred Monsanto’s 2018 sale to Bayer. The 2015 IARC label of glyphosate as a probable carcinogen sparked massive litigation, culminating in a 7-2 Supreme Court decision granting Bayer immunity and shaping future pesticide lawsuits.
