Delhi's air pollution has soared, with AQI levels measured at over 1,500, forcing authorities to shut schools and halt construction. Poor air quality is exacerbated by stubble burning and emissions from vehicles and industries. The government has implemented stricter measures under the GRAP 4 plan, yet residents report severe health issues, raising calls for long-term solutions. Each year, northern India suffers from hazardous air quality, which remains a persistent public health crisis, leading to over a million deaths annually from pollution-related illnesses.
