October was a better month for Delhi in terms of low pollution as compared to November when the pollution was high. Pollution is always high in November because of the festival of Dushera. In fact, due to the burning of effigies of demons on this auspicious day, the air quality gets quite poor. The air quality has a lot of soot in it during this time. It’s due to the paper of effigies which gets burnt during Dushera.

Now, India has a lesser life expectancy than other countries whereas the life expectancy is 6 years more in many Asian countries. The Energy Policy Institute at the University of Chicago has declared that pollution reduces human health by as much as 1.8 years due to which it is the biggest danger to the health of humans.
