MADRID (CBS) — An interactive art installation is leaving people short of breath – and thinking about the impact of air pollution. Check out the exhibition that opened Wednesday on the sidelines of the UN Climate Change Conference COP25 in Madrid, Spain.

Spain is plagued by three main pollutants — nitrogen dioxide caused by traffic, particulate matter which consists of dust, ash and soot and finally ozone.
