Monsanto’s Roundup herbicide is widely used globally, but has been linked to a mysterious fatal kidney disease among farmers in Central America, Sri Lanka and India. Dr. Jeff Ritterman, M.D., member of Physicians for Social Responsibility (San Francisco, CA), and global humanitarian, explains how Roundup may bind toxic metals and deliver them to kidney tubules, leading to widespread fatal kidney disease. Ritterman’s investigation into the herbicide has led him to conclude that it should be banned. Ritterman also shared his global insights into health and disease, recommending that we focus on equity, the food system, and energy/climate change.
