I am inspired by the stand taken by the Honourable Supreme Court in temporarily banning firecracker sales in the National Capital Region (NCR). The idea is to test whether it cuts the deadly pollution levels seen in Delhi during and after the festive celebrations of Deepavali. There is something about the Delhi air and it gets worse with the onset of winters because of firecrackers and also the crop-residue burning in Punjab and Haryana, which too was banned in 2015. It is a different matter that people still burn firecrackers and farmers continue to burn crop residue.
