Expert Answer
- Thermal pollution can be defined as a rise in the temperature of water bodies largely due to human activities.
- Thermal power plants use water as a cooling agent in their plants. They are located near the rivers. When these plants release recycled hot water into the rivers, temperature of water rises resulting in thermal pollution.
- Thermal pollution can have disastrous effects on organisms living in water as hot water does not have the same oxygen holding capacity as cold water. Some water organisms which require higher concentration of oxygen in water either die or migrate to some other water bodies. Blue algae thrive well in warm waters which produce considerable amount of toxins endangering the lives of aquatic organisms.
