Record-breaking smog is blanketing eastern Pakistan and northern India, creating hazardous conditions which are even visible in satellite images. A dense haze stretches from Pakistan’s Punjab province to India, impacting tens of millions. Lahore’s air quality index hit a hazardous 1,200, far exceeding the danger threshold of 300. The fine pollutant PM2.5, linked to serious health risks, registered 110 times over safe levels. Hospitals are overwhelmed, with over 30,000 cases of respiratory issues reported. Schools, government offices, and public spaces have been closed for a week. Children are particularly vulnerable, as UNICEF warns that over 11 million under-fives are exposed to toxic air. Authorities are urging cooperation with India to address this cross-border crisis. The climate crisis and reliance on fossil fuels compound the issue, contributing to deadly pollution worldwide.
