DNA: How can Delhiites live in such bad air?

Even before Diwali, Delhi's air has become poisonous. Air pollution is increasing very rapidly in the capital Delhi. Seeing the way air pollution has increased in the morning, the memories of the past years have become fresh again...when people had stopped walking due to pollution in the morning...people used to go out wearing masks even during the day. ...AQI i.e. Air quality index had reached red color...this is the story of last year, but even this year the situation is not better.
