The challenge of ending plastic pollution

The latest gathering of the world's nations to come up with a treaty to end plastic pollution ended on Tuesday. One area of disagreement was how to address greenhouse gas emissions generated in the manufacture of plastics. Industry groups want the treaty to focus on reuse and recycling. Most other stakeholders want to phase out the use of plastic. Host Marco Werman speaks to Kristian Syberg, a plastics pollution specialist at Roskilde University in Denmark who attended the talks in Ottawa.
