Judith Enck, whose new book "The Problem with Plastic" confronts one of the defining environmental issues of our time. Enck brings decades of experience - from her work at the EPA to her leadership of Beyond Plastics - to this investigation into the plastics crisis: how a material once celebrated for innovation now chokes our oceans, clogs our recycling systems, pollutes our air and bodies, and wreaks havoc in communities bearing the brunt of petrochemical extraction and waste.
