"Pollution Pods" The artist created a series of interlinked geodesic domes which contained polluted air from cities around the world. There was some confusion and concern about whether the environments within the domes could have a detrimental impact on visitors' health. During an interview for BBC1, the presenter David Sillito was "'speechless"' when the artist explained that he could not use genuine London air within the London pod. The "Pollution Pods" have been exhibited at the Starmus Festival, Trondheim, Somerset House, London, World Health Organisation's first international conference on Air Pollution, Place des Nations, Geneva, , Germany, TED Annual Conference, Vancouver, Canada, Science Gallery Melbourne, Australia, UN Climate Action Summit, UN Buildings, New York City, and COP 25, Madrid. Greta Thunberg when visiting the "Pollution Pods" remarked "It’s an incredible exhibition, It’ll really bring attention to these problems, and if people can experience this, people from all around the world, how these people live everyday, it will bring lots of attention and people will be more encouraged to deal with these problems". Dr Tedros Adhanom tweeted that the "Pollution Pods" successfully raised awareness about impacts of air pollution on health. Teresa Ribera, Minister for the Ecological Transition of Spain, said: “"Air pollution and climate change are the two sides of the same coin. The symbolic installation of the Pollution Pods at COP25 should remind everybody that we are negotiating for cleaner environments, cutting emissions and gaining better health for all".” Artnet rated the "Pollution Pods" as one of the 100 Works of Art That Defined the Decade. Stir Magazine listed Pollution Pods as one of the ten most unforgettable artworks of 2019.
