U.N. conference visitors experience polluted city air with climate simulator

On Monday, visitors at the 2019 U.N. Climate Change Conference (COP25) in Madrid, Spain, had the chance to experience Pollution Pods, an installation created by artist Michael Pinsky, that showed what it would be like to live in heavily polluted cities. The installation used fog machines and perfume blends to mimic different air qualities from places like Sao Paulo, London, and New Delhi.
