10 Lines on Thermal Pollution

Thermal pollution is the degradation in the quality of water due to the harmful release of heated liquid to aquatic bodies like the sea, ponds, and rivers from industries, power plants, and manufacturing units as a waste product. Thermal pollution has a detrimental impact on our ecosystem. The heated water from the industries in form of coolant changes the ambient water temperature of the aquatic bodies like sea, river and ponds. The sudden change in temperature decreases the level of oxygen in the water leading to major threat to various microorganisms and fishes in ocean.

Ten Lines on Thermal Pollution

Set 1

1) Thermal pollution is the degradation in the quality of water through an industrial process.

2) The main cause of pollution is using water as a coolant in industrial power plants.

3) The water used as a coolant can create a sudden change in aquatic water bodies.

4) The temperature change decreases the oxygen supply and impacts aquatic life.

5) Fishes and other sea animals are killed due to thermal pollution.

6) Hydro electric power plants, nuclear power plants, manufacturing industries are major contributors to thermal pollution.

7) Thermal pollution may increase the metabolic rate of a living organisms of aquatic bodies.

8) The rising temperature of the water increases the toxicity by changing its physical and chemical properties.

9) Cooling ponds, cooling towers, and artificial water bodies are used for controlling the thermal pollution.

10) The abrupt change in water temperature either increase or decrease is known as ‘thermal shock’ impacting aquatic organisms.


Set 2

1) Industrial effluents for example waste from research institutions and hospitals emit enough heat materials causing thermal pollution.

2) Continuous soil erosion may result in thermal pollution by increasing the surface area of the water exposed to sunlight.

3) Deforestation leads to an increase in the compounded temperature of the atmosphere giving rise to thermal pollution by changing the temperature of the water.

4) Geothermal activity and active volcanoes can increase the temperature of water bodies having a significant impact on marine life.

5) The runoff water from urban sewage, roads and parking lots finally meet the aquatic bodies leading to thermal pollution.

6) Treating the warm discharged water from industries before releasing it to aquatic bodies can control thermal pollution.

7) Thermal pollution if not controlled may lead to the mass migration of marine species for the survival of life to a suitable environment.

8) Recycling and reuse of heated water can control thermal pollution to some extent.

9) Industries and plants should look for alternative cooling agents other than water like oil.

10) The heated water from industries should not be released to aquatic bodies with a sensitive ecosystem rather artificial lakes should be prepared for water collection.


Set 3

1) Thermal Pollution is the degradation of water quality by a change in its ambient temperature.

2) The use of water as a coolant by industries and power plants is one of the main causes of thermal pollution.

3) The sudden release of hot water into water bodies results in oxygen depletion and unstable ecosystem.

4) Runoff water from roads and urban areas causes elevated water temperatures i.e. thermal pollution.

5) Thermal pollution harms and threatens the existence of fishes and other aquatic organisms.

6) Thermal pollution also affects the biodiversity of the affected area and considerably reduces it.

7) Thermal pollution leads to low oxygen and high bacterial level in the water bodies.

8) Power plants are one of the main contributors of thermal pollution in the world.

9) To prevent thermal pollution, water from industrial sources must be cooled before letting into open.

10) There is a need to break conventional working methods and start thinking of the environment.

Set 4

1) Thermal Pollution occurs when natural water is either cooled or heated due to human activities.

2) Plants drawing water from nearby sources as coolants, release back hot water into the environment.

3) Soil erosion also leads to thermal pollution by raising the water bodies, causing more exposure to the sun.

4) Deforestation also causes thermal pollution by raising the temperature of water bodies.

5) Global warming due to various human activities is also the main cause of thermal pollution in the world.

6) The higher environmental concentration of greenhouse gases also causes thermal pollution.

7) The natural causes of thermal pollution are volcanoes and other geothermal activities.

8) The sudden thermal shock could be threatening to aquatic organisms, causing their large scale killing.

9) Warming up of water also causes migrations of a particular species to a suitable environment.

10) Cooling ponds and cooling towers are some of the best ways to control thermal pollution.


Many people have a limited understanding of thermal pollution because they think that it doesn’t have a direct impact on humans. But in reality, thermal pollution is gradually impacting our ecosystem by damaging marine life.

It is essential to educate people about the harmful effects of thermal pollution so that they can contribute towards preserving marine life by reducing their own carbon footprint. The government should also frequently take steps and measures to control thermal pollution by implementing standard operating procedures for waste disposal for industries and manufacturing plants.
