Explain thermal pollution and its effect on aquatic life .

Explanation

Thermal power plants located near water bodies use water for cooling the machineries and release the hot water back into the water bodies. This affects the aquatic life. The hot water can hold less oxygen compared to normal water. The reduction in the percentage of oxygen in water affects fish like trout. Warm water increases the growth of blue-green algae that produce some toxins. The rise in the temperature of water increases the solubility of salts.
