Industrial Pollution

There are many causes of industrial pollution, the negative by-products of human industry. One of the main sources is the pollution caused by energy production. By-products produced through industry are another major component of this type of pollution. Besides pollution unique to specific sources, the release of carbon dioxide gas from various industrial sources is a key cause of global warming. The first main source of industrial pollution is the production of electricity. In coal-burning power plants, fly ash is the by-product of burned coal. Once incinerated directly into the atmosphere, most fly ash in the 21st century is either recycled or stored in vast holding ponds.

Outside of energy production, all factories produce some form of pollution. Some of the most harmful to humans and the environment are heavy metals produced as a result of metal refining. Copper, mercury and lead can accumulate in animals throughout the food chain. One of the most harmful forms of industrial pollution is carbon dioxide gas released through the burning of coal and oil. Its increasing presence in Earth's atmosphere is a direct cause of global warming. Despite efforts of developed nations to reduce carbon dioxide emissions, the lax industrial regulations of developing countries have led to a continued increase in emissions.
