The festival of lights sparks a conversation around green crackers, recurring bans, health concerns and the question of a just transition for Sivakasi.

Restrictions are announced, courts intervene, and conscientious citizens urge people to celebrate without adding to pollution. The arguments can quickly turn acrimonious, with those calling for restraint often accused of opposing religious traditions.
