The dense smog of Delhi and the haze of Beijing cloud the sky as visitors sniff the air during a unique exhibition in London aimed at raising awareness of pollution.
The new art installation allows people to experience different pollution levels using five domes that replicate the environments of the Indian, Chinese and British capitals, Brazil's Sao Paulo and Norway's Tautra peninsula.
British artist Michael Pinsky, whose work often focuses on environmental issues, told the Thomson Reuters Foundation he wanted to make people stop and think about how their everyday actions impact the atmosphere.
