Directions (Qs. 96-100): Read the following passage carefully and answer the questions that follow. Air pollution has emerged as one of the gravest environmental challenges of the 21st century, particularly in rapidly urbanising regions of Asia and Africa. While economic expansion and urban growth have lifted millions out of poverty, they have also intensified the concentration of harmful pollutants such as particulate matter (PM2.5 and PM10), nitrogen oxides, carbon monoxide, and ground-level ozone. Unlike the visible soot and smog of the industrial revolution, today’s pollution is more insidious, operating at a microscopic level and silently undermining human health and ecological stability. According to global health reports, prolonged exposure to fine particulate matter can cause chronic respiratory illnesses, cardiovascular disorders, and even premature death. Yet, despite the well-documented consequences, policy responses often remain fragmented and reactive. A systematic solution to the air quality crisis must begin with comprehensive monitoring. Many cities lack reliable, real-time data, making it difficult to identify pollution hotspots or enforce emission norms effectively. Expanding the network of air quality sensors and integrating satellite-based data can create a more accurate picture of pollution dynamics. This data-driven approach would allow authorities to implement targeted interventions rather than blanket restrictions. Secondly, the transportation sector demands structural reform. Vehicular emissions constitute a major share of urban pollution. Promoting electric mobility through subsidies, expanding public transport, and improving last-mile connectivity can significantly cut tailpipe emissions. Simultaneously, strict inspection and maintenance regimes for older vehicles should be enforced to phase out the most polluting fleets. Industrial emissions require equal attention. Establishing green industrial corridors, adopting cleaner production technologies, and introducing market-based mechanisms such as emission trading schemes can reduce the carbon and pollution footprint of manufacturing zones. Additionally, transitioning from coal to renewable energy sources like solar, wind, and bioenergy can gradually decouple economic growth from environmental harm. At the community level, awareness and behavioural change are indispensable. Citizens can contribute by reducing household waste burning, conserving energy, and supporting local green initiatives. Schools and civic bodies must incorporate environmental education to instil sustainable habits early on. Moreover, coordinated regional action is vital because air pollution does not respect administrative boundaries. Countries sharing airsheds — such as India, Bangladesh, and Nepal — must collaborate on emission inventories, early warning systems, and technology exchange. In essence, clean air cannot be achieved through isolated efforts or temporary bans. It demands an integrated policy framework that combines technology, governance, public participation, and transnational cooperation. The air we breathe is a shared resource, and its protection requires a collective commitment to sustainability, accountability, and scientific precision.
