Murky air means money for New Delhi businessman Jai Dhar Gupta.

The 43-year-old Wharton graduate began selling pollution masks last year in India, home to some of the planet’s most toxic cities. Gupta reckons he’ll sell 70,000 from January to March -- as much as the whole of 2015 -- and may buy an equity stake in the U.S. company that owns the rights to the products.
