Berlin | Reuters — Bayer said it would invest five billion euros (C$7.5 billion) in developing new weedkillers and reducing its environmental impact by 30 per cent by 2030, as it seeks to address the fallout from U.S. class-action litigation over glyphosate. “While glyphosate will continue to play an important role in agriculture and in
