In the wake of the pollution situation, the Delhi government even considered the idea of artificial rain to tackle the foul air in the city, until sudden rainfall brought a major respite, lowering the pollution level. However, after yesterdays celebrations, everything is going to be in vain.The latest posts shared on social media sites and reports have shown that a large number of people at different places have taken part in the burning of firecrackers. Sunday nights visuals from Lodhi Road, RK Puram, Karol Bagh, and Punjabi Bagh showed intense fireworks lighting up the night sky across several areas in Delhi.Report on Delhis AQIAccording to the report, in October, the AQI was at its worst. The concentration of PM 2.5 in the city has been recorded at 20 times the limit prescribed by the World Health Organisation (WHO), prompting the city government to order the closure of all primary classes and restrict the entry of trucks.Despite the Delhi governments Diya Jalao, Patakhe nahi campaign and the Supreme Courts order on firecrackers, rising pollution is likely to dim the light in the city after festivity ends.
