New Delhi - Prashant Kalra relocated to the western coastal city Goa five years ago because the dirty air in the Indian capital and surrounding towns was making his three-year-old daughter sick.
"Our daughter could not breathe in Delhi-NCR," said Kalra, who lived in Gurugram, a city adjacent to New Delhi. "She needed a nebulizer every night just to go to sleep. That convinced us that we did not have a choice."
