First, let’s get this straight. There are no safe levels of air pollution. Experts speak in one voice when they say this, whether it is the World Health Organization (WHO), the National Institutes of Health, the American Journal of Respiratory and Critical Care Medicine or others. Episodic high pollution levels like what happens in north India during peak stubble burning or Diwali may dramatically increase visits to hospital emergency rooms, but even lower pollution levels also cause disease, disability and death.
Nearly 1.7 million people die from air pollution each year — which is more than three times the. . .
