There are several types of pollution, and while they may come from different sources and have different consequences, understanding the basics about pollution can help environmentally conscious individuals minimize their contribution to these dangers.

From the different types of pollution, we can understand that they have been affected by so many causes. For air pollution, it comes from a wide variety of sources. Some of the most excessive sources include vehicle or manufacturing exhaust, forest fires, volcanic eruptions, dry soil erosion, and other natural sources, building construction or demolition. Depending on the concentration of air pollutants, several effects can be noticed. Smog increases, higher rain acidity, crop depletion from inadequate oxygen, and higher rates of asthma. Many scientists believe that global warming is also related to increased air pollution. Meanwhile, causes of water pollution include increased sediment from soil erosion, improper waste disposal and littering, leaching of soil pollution into water supplies, organic material decay in water supplies. The effects of water pollution include decreasing the quantity of drinkable water available, lowering water supplies for crop irrigation, and impacting fish and wildlife populations that require water of certain purity for survival. In addition, thermal pollution has been caused by so many things. Thermal pollution may be caused by power plants, urban sprawl, air pollution particulates that trap heat, deforestation and loss of temperature moderating water supplies. As temperatures increase, mild climatic changes may be observed, and wildlife populations may be unable to recover from swift changes.
