Causes of thermal pollution?
Discharge of warmed water from power plants and other industrial plants, into rivers and lakes. Discharge of hot combustion gases into the atmosphere. Vehicle exhausts and aircon discharges in cities. More roads and buildings absorbing heat and passing it to the air, mainly in cities.
There are many causes of environmental pollution. Contaminates released into the water evaporate and are spread through rain. Carbon monoxide, nitrogen oxide, and other gases are released into the air causing pollution. Noise pollution, light pollution, visual pollution, and thermal pollution are other types of pollution that are affecting the environment.
Thermal pollution is characterized by the increase or decrease in water temperature within streams, rivers and any natural bodies of water. The causes of thermal pollution are the removal of trees from the area that would normally provide shade and from factories or power plants that may dump the waste of hot water produced into the natural bodies of water.
