Delhi’s air quality has deteriorated sharply since late October, especially after Diwali, with the AQI reaching hazardous levels around 478. Residents like Sheetal Sharma and auto-rickshaw driver Dinesh Kumar suffer from severe respiratory issues, forcing many to seek refuge in cleaner areas. Despite governmental measures, the pollution remains high year-round due to geographical disadvantages and external sources. Economically, air pollution costs Delhi 6% of its GDP annually and affects lower-income groups disproportionately. Experts suggest shifting investment towards sustainable urban infrastructure and public transport to combat the ongoing crisis and mitigate long-term impacts on health and the economy.
