hi dear!
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 ecosystem composition.

When the industries excrete the warm water directly into water bodies without cooling it down , this leads to increase in temperature of water bodies and due to increase in temperature , dissolved oxygen reduces and aquatic life is harmed and this is how thermal pollution is caused.
