This photograph taken on February 25, 2017, shows a Pakistani worker watching smoke rising from factories on the outskirts of the northwestern city of Peshawar. Pakistan's cities are gasping for clean air amid dire warnings from the World Bank, but officials say they are helpless to combat the looming calamity due to a lack of basic data. The fast-growing country is home to some 200 million people and suffers from some of the worst air pollution in the world, thanks to its giant population plying poorly maintained vehicles on the roads and unchecked industrial emissions. / AFP PHOTO / ABDUL MAJEED / TO GO WITH 'PAKISTAN-ENVIRONMENT-POLLUTION-AIR', FOCUS BY MASROOR GILANI (Photo credit should read ABDUL MAJEED/AFP via Getty Images)
