Like Diwali, air pollution has also become a part of north India's ritual, one that no one looks forward to but is a byproduct of everything that is wrong with urban India - mis-governance, political apathy, lack of concern for the environment, poor implementation of green laws, improper planning etc. Policymakers were well aware of the impending crisis of air pollution, but little or nothing was done to prevent it. Small yet meaningful measures such as vacuuming of roads, sprinkling of water was not done.
