Severe Smog Shuts Down Major South Asian Cities, Making Thousands Sick

Pakistani city Lahore among worst affected with Air Quality Index soaring beyond hazardous levels; experts attribute smog to pollution from industries, vehicles and residue from crop burning.

Major South Asian cities, including Lahore in Pakistan and several in India, Nepal and Bangladesh, have shut down schools, businesses and public spaces due to severe smog that has given rise to illnesses and exacerbated respiratory conditions in thousands of people.
As of Friday, four out of the top five cities with the worst air quality in the world were in South Asia, with Lahore recording an Air Quality Index (AQI) of 432 - well above the hazardous level of 301, and thousands falling sick.
Pollution from industries, vehicles, and residue from crop burning have been identified as the main culprits, with the burning of crop residue being a key cause of the smog, especially at the start of the winter wheat-planting season.
To combat the hazardous smog, local authorities have imposed movement restrictions, closed down non-essential services, and advised residents to wear masks and stay at home; however, these measures have not prevented a spike in respiratory and other health issues.
The World Health Organization has identified air pollution as a leading risk factor for death and disability in countries like Nepal; moreover, studies indicate that high pollution levels could reduce the life expectancy of residents in regions like Delhi, India, by up to nine years.
