Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere.
Causes: 1. Emissions From Industrial Plants and Manufacturing Activities: With the current rate of industrialization and increased manufacturing activities, high levels of smoke, sulfur dioxide, and particulate matter are emitted into the air.
2. Combustion From Fossil Fuels: In the modern world, fossil fuel combustion is the biggest contributor /kənˈtrɪbjətər/ to air pollution. The leading culprit (преступник) today is traffic, but factories and power plants also continue to contribute /kənˈtrɪbjuːt/ to some extent. Conventional power plants that combust /kəmˈbʌst/ fossil fuels to produce energy emits /iˈmɪt/ hazardous /ˈhæzədəs/ gases into the air.
3. Farming Chemicals and Household Products: Use of household and farming chemicals produce considerable amounts of harmful foreign substances into the atmosphere and have the potential to cause air pollution. Dusting of crops, painting supplies, home fumigation, household cleaning products, fertilizer powder, insect/pets sprays, hair sprays, and deodorant sprays release harmful chemicals into the air, causing pollution.
4. Natural Causes of Air Pollution: The majority of people only perceive air pollution as a consequence of human actions. In some cases, natural events can as well cause air pollution. However, they are rarely witnessed, and some of them are very disastrous and difficult to prevent from happening (volcanic eruptions, whirlwinds, forest fires, and gaseous releases from decaying plants and animals or radioactive decay of rocks).

In some regions, waste is incinerated instead of being land-filled or recycled, that contributes to air pollution. Some agricultural practices like burning agricultural land after harvest or burning as a mechanism for clearing land cover is also a significant cause of air pollution.
