Lahore, dealing with a severe smog crisis, reclaimed its title as the world's most polluted city on Wednesday. The air quality index (AQI) by IQAir, a Swiss air quality technology company, consistently registered above 381, indicating very unhealthy air. The peak AQI, nearing hazardous levels, hit 580 around DHA Phase 3, while the lowest recorded AQI around Aitchison College still lingered in the hazardous levels range at 350. The severe impact of smog on human health and the environment cannot be ignored. It can cause or worsen respiratory and cardiovascular diseases, such as asthma, bronchitis, emphysema, and even heart attacks. Smog's effects extend to irritating the eyes, nose, and throat, reducing visibility, and diminishing overall quality of life.

Furthermore, it poses threats to crops, plants, and buildings, contributing significantly to global warming and acid rain. Experts suggest viable solutions, including enforcing stricter emission standards and regulations for vehicles, industries, power plants, and brick kilns. Additionally, they advocate for the adoption of cleaner fuels and increased reliance on renewable energy sources like solar, wind, and hydropower.
