Every year around the crop harvest season, the entire country wears a pall of crop-burning gloom. There’s smog everywhere and the air quality index takes a further deep dive to show alarming number of pollutants in the air we breathe.

Not surprisingly, of the 30 most air polluted cities in the world, 22 are in India. And New Delhi is the most polluted capital city in the world. The need to address India’s air pollution is dire. It’s time we all sat up and smelled the pollution.
