Detailed explanation-1: -A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the sudden change in temperature decreases oxygen supply and affects the ecosystem.
Detailed explanation-2: -The thermal pollution of water bodies is mostly caused by the hot water or discharge of heat (hot water) from power plants and related industries.
Detailed explanation-3: -Whilst thermal power plants give out a lot of gases that are harmful to the environment, they also give out what is known as thermal pollution. Thermal pollution is the degradation of the local environment, in particular the localized waterways, that are changed by the discharge of waste water from the power plant.
