Air pollution refers to the presence of harmful substances in the air, including gases, particulates, and biological molecules. These substances can have detrimental effects on human health, as well as the health of other living organisms and the natural environment.
There are many sources of air pollution, including power plants, factories, vehicles, and household products. Burning fossil fuels such as coal, oil, and natural gas releases a variety of harmful substances into the air, including carbon dioxide, nitrogen oxides, and particulate matter. Industrial processes, such as those used in manufacturing and agriculture, can also contribute to air pollution.
The effects of air pollution can be severe and wide-ranging. Short-term exposure to air pollution can cause respiratory problems, headaches, and other health issues. Long-term exposure can increase the risk of developing serious health problems such as heart disease, stroke, and cancer.
