Pollution refers to the presence or introduction into the environment of a substance or thing that has harmful or poisonous effects. Pollution can take many forms, including air pollution, water pollution, and soil pollution. Air pollution is the contamination of the air by harmful substances such as carbon dioxide, sulfur dioxide, and nitrogen oxides, which can be produced by the burning of fossil fuels or the release of chemicals from industrial processes. Water pollution is the contamination of water bodies, such as rivers, lakes, and oceans, by harmful substances such as pesticides, fertilizers, and industrial waste. Soil pollution is the contamination of soil by harmful substances such as heavy metals and toxic chemicals, which can be released into the environment through industrial processes or the improper disposal of waste.
