Air Pollution | Biology

In a broad sense, air pollution means the presence of chemicals or compounds (called pollutants) in the air which are not naturally occurring, and which lower the quality of air, and are harmful to all living things in the atmosphere. Air pollution is majorly caused due to the release of various chemicals into the atmosphere. Air pollution can be both man-made and naturally occurring.
In our current age of industrialization and modernization, the biggest source of air pollution is the burning of fossil fuels. For example, when we burn petrol or diesel or coal to run our cars, machines, trains, power plants, etc. this releases harmful pollutants into the atmosphere, endangering all living things around.
