Kanpur, with a population of three million faces a pollution crisis. Last month’s report by WHO pegged it at the head of 14 Indian cities in the world’s top 15 with the dirtiest air. The pollution in the city has taken toll on the life of residents and caused a major jump in the number of patients reporting breathing problems. The official response acknowledges the ripples caused by the WHO findings, but says time will tell if the city’s industrial and vehicular pollution can be reigned in.
