Record amounts of glyphosate sprayed in California forests

Season 2026 Episode 172 | 9m 20s

An investigation by the Center for Investigative Reporting has revealed that glyphosate is being sprayed in California forests at record levels by timber companies and the U.S. Forest Service. Glyphosate, the active ingredient in Roundup, kills vegetation that competes with young trees. The weedkiller has been the subject of lawsuits alleging exposure caused cancer. Nate Halverson reports.
