History

Historical Context

In 2018, a California jury awarded $289 million to Dewayne Johnson, a groundskeeper who claimed Roundup caused his cancer, marking a pivotal moment in Bayer's ongoing legal battles over glyphosate. Following the International Agency for Research on Cancer's 2015 classification of glyphosate as "probably carcinogenic," over 42,000 lawsuits emerged, reflecting the tension between agricultural practices and public health concerns.
