One type of pollution is thermal pollution (power plants, industries often dump heated water in a reservoir that reduces the amount of oxygen increases the toxicity of contaminants, violates biological equilibrium). Resetting the warm waters of the enterprises is unfavorable factor for aerobic organisms that live in fresh water. In the warm water oxygen is poorly soluble, and its deficiency results in some places many organisms to death.
