NRDC comments detail how the Environmental Protection Agency (EPA) has utterly failed to evaluate the human health risks including cancer and noncancer risks, and the ecological risk that glyphosate poses to wildlife including monarch butterflies. Since the last ecological risk assessment was completed for glyphosate in 1993, its use has skyrocketed resulting in glyphosate being the most widely used pesticide in the US. In that time, mounting evidence has pointed to adverse human health effects as well as the precipitous decline of the North American monarch butterfly population. Based on the combined data, NRDC details why the EPA needs to severely restrict the use of glyphosate and glyphosate-based products immediately. Document ID: EPA-HQ-OPP-2009-0361-0066.
