Air pollution is a serious environmental and health challenge in India, affecting millions of people, especially in urban areas. The main causes include vehicle emissions, industrial smoke, construction dust, crop stubble burning, and excessive use of fossil fuels like coal and diesel. Cities such as Delhi, Kanpur, and Lucknow often record high pollution levels, especially during winter, when smog reduces visibility and makes breathing difficult. Air pollution leads to health problems like asthma, lung infections, heart diseases, and eye irritation. It also harms the environment by damaging crops, reducing air quality, and contributing to climate change. To control this issue, the government has introduced steps like promoting electric vehicles, creating pollution control laws, improving public transport, and running awareness campaigns. However, public participation is equally important—using less plastic, planting more trees, avoiding burning waste, and switching to cleaner energy can help reduce pollution. Clean air is essential for a healthy population and a sustainable future for India.
