Whoever starts moaning about Delhiās air quality doesnāt live here or is ignorant of its geography.
Itās the same number of people living here, same number of vehicles, same level of industrial activity happening throughout the year yet the pollution peaks during diwali season.
Now these alarmist people will put the agenda that firecrackers, vehicular etc are the cause of this pollution but the real reason is as we approach winter season, air becomes denser, thereās no wind hence the particle remains suspended in the air.
Itās in this season where farmers also start stubble burning which adds on to the already polluted air.
Itās a period for 1-2 months and has been there since beginning. Atleast people who are actual delhites know this.
In my opinion Mumbai is even more polluted than Delhi but being a sea shore, it gets sea winds which naturally cleans up the air.
