It’s been known for some time that inhaling polluted air can cause infections and disease. It causes 7 million premature deaths a year. Now more studies are revealing in greater detail just what damage fine particles are doing to our bodies. Joining us is Johan Kuylenstierna, Policy Director at the Stockholm Environment Institute; Arvind Kumar, Co-Founder of the Lung Care Foundation; Aaron Kiely, Clean Air Campaigner at Friends of the Earth and Liza Selley, Air Pollution Toxicologist at King’s College London. Roundtable is a discussion programme with an edge. Broadcast out of London and presented by David Foster, it's about bringing people to the table, listening to every opinion, and analysing every point of view. From fierce debate to reflective thinking, Roundtable discussions offer a different perspective on the issues that matter to you. Watch it every weekday at 15:30 GMT on TRT World.
