• Forest Ecosystems: Deforestation and forest fires contribute to air pollution, further exacerbating the issue.
• Urban Ecosystems: Urban areas experience high levels of air pollution from vehicular emissions, industrial activities, and construction dust. This has led to the decline of green spaces and an increase in concrete jungles.
• Water Ecosystems: Water bodies, including rivers and oceans, are impacted by air pollution through the deposition of pollutants and the alteration of water chemistry.

In conclusion, air pollution in India has far-reaching consequences for the country's environment, affecting natural surroundings and various ecosystems. Addressing these issues is crucial for the well-being of India's diverse natural habitats and the long-term sustainability of its ecosystems.

The sources of air pollution in India

India's air pollution is a serious environmental issue. In 2019, 21 of the 30 most polluted cities in the world were in India. A 2016 study revealed that at least 140 million Indians breathe air that is 10 times over the WHO safe limit. India's particulate air pollution comes from a variety of sources, including industrial and vehicular emissions, construction dust, dependence on thermal power, waste burning, and the use of wood and dung for cooking and heating.

Industrial Pollution

Industrial pollution is the largest contributor to India's air pollution, causing 51% of it. Industrial emissions are a significant source of PM2.5, which are small particulates with a diameter of less than 2.5 microns. These particulates can cause deadly illnesses such as lung cancer, stroke, and heart disease.

Vehicular Emissions

Vehicular emissions are the second largest contributor to India's air pollution, accounting for 27% of it. In addition to emissions from vehicles, traffic congestion also contributes to air pollution. Slow-moving vehicles in congested traffic burn fuel inefficiently and pollute more per trip.

Crop Burning

Crop residue burning is a major source of smoke, smog, and particulate pollution, especially during the autumn and spring months when it is used as a cheaper alternative to mechanical tilling. Crop burning accounts for 17% of India's air pollution.

Other Sources

Other sources of air pollution in India include construction dust and debris, the use of thermal power for electricity, waste burning, and the burning of wood and dung for cooking and heating. These sources collectively contribute to about 5% of India's air pollution.
