Delhi's air quality has deteriorated to severe levels, leading to significant health concerns. In response, schools have been directed to implement hybrid classes for primary students, while non-essential construction activities have been banned. The Central Pollution Control Board reported PM2.5 levels at 438, which is alarmingly high compared to the World Health Organization's safe limit of 15. Doctors recommend that residents, particularly vulnerable groups like children and the elderly, stay indoors unless necessary. The worsening air quality is attributed to various factors, including industrial emissions and crop burning. The Delhi government has activated stage three of its Graded Response Action Plan, which includes bans on mining and vehicle movement that generates dust. This crisis has sparked protests and political accusations regarding the government's transparency in reporting air quality data.
