Every year, as soon as Diwali comes, the discussion of firecrackers and pollution starts gaining momentum. While many states ban the sale of firecrackers on Diwali, many states allow only green firecrackers. This year also, different states have issued different guidelines on the use of firecrackers. Many states have completely banned firecrackers, while many states have allowed the bursting of firecrackers only for 2 hours.
Banning the use of firecrackers during Diwali raises the question of whether crackers cause pollution? If firecrackers cause pollution, then is it that firecrackers cause maximum pollution? What chemicals are in firecrackers, which are dangerous for your health? And which firecracker spreads how much pollution? Let’s know.
