Visitors walk through British artist Michael Pinsky's Pollution Pods, a new sensory work, installed in the courtyard at Somerset House in London to mark Earth Day 2018. A series of five connecting domes recreate the pollution from London, Beijing, São Paulo, New Delhi and Tautra in Norway. Visitors are invited to experience first-hand the difference in the air quality of global environments. The Pollution Pods are open until 25th April 2018, including Earth Day on the 22nd April.
