Roundup, the world’s most widely used herbicide, contains glyphosate — a chemical the World Health Organization classified as "probably carcinogenic to humans" in 2015. Monsanto, which created Roundup, was acquired by Bayer in 2018. Internal documents revealed Monsanto knew of cancer risks but chose to suppress the science and attack independent researchers. Juries have awarded billions in damages, and Bayer has paid over $11 billion in settlements.
