Two years ago, Rane noticed an alarming trend. Respiratory ailments, chiefly among children, were on the rise. "It was truly a pathetic sight." As president of an organisation that calls itself the Smoke Affected Residents Forum, he knew it was his business to go into the heart of the matter. Encouraged by the Supreme Court directive last year on the Euro norms, Rane filed a public interest litigation in the Mumbai high court in the middle of last year. Not only that, he even went on a hunger strike in front of a suburban regional transport office.
