(1) 200 Words – Essay on Thermal Pollution for Kids & Students in Very Easy Words
Any type of pollution that changes the natural temperature of water on an undesirable scale is called thermal pollution. One of the common causes of thermal pollution is the use of cold water by power plants and industrial manufacturers. When the water used for cooling returns to its natural environment, its temperature is high. Due to the increase in temperature, the amount of dissolved oxygen in the water starts to decrease, due to which the conditions for life become unfavorable.
Usually coal is burnt to generate thermal energy from which the generated energy is converted into electrical energy but in the process when coal is burnt many gases are released which contaminates the atmosphere. These gases mainly include carbon monoxide, sulfur di-oxide, nitrogen oxide, hydrocarbons and fly ash etc. As their concentrations increase, thermal pollution spreads in the atmosphere.
In addition, if the power-producing power plant suddenly stops, the water temperature decreases simultaneously. This is called thermal shock. Usually, fish are not able to tolerate this. It adversely affects aquatic animals, many organisms are eliminated and it becomes fatal to fish and other creatures. The ash from its chimney, which is harmful due to overheating and where it rains, destroys trees and plants.

In many forms of pollution, thermal pollution intensifies natural outbreaks such as floods, droughts and famines. It also causes dangerous rise in sea level. Continuous rise in heat can cause glaciers to melt, causing great harm to organisms. The possibility of climate change is increased by thermal pollution which has severe side effects on agricultural production.
Thermal pollution is any type of pollution process that drastically changes the natural temperature of water. The main cause of thermal pollution is due to the use of coolant water by power plants and industrial manufacturers. There is a decrease in the amount of oxygen which also affects the ecosystem. Radioactive materials are also major pollutants.
Another cause of thermal pollution is the exhaling of too much cold water in hot rivers by reservoirs. This affects the production of fishes (especially eggs and larvae). There is a decrease in the amount of water-soluble oxygen (dissolved oxygen) due to the higher temperature. Lack of oxygen content can cause damage to fishes, amphibians, and copepods. Thermal pollution also affects the metabolic processes of water creatures.
Changes in the metabolic process can cause a decrease in food content, resulting in a very rapid decrease in population. Changes in the environment can cause organisms to move from one place to another where the environment is favorable; Similarly, those fish can also change their location, which may be elsewhere only to live in warm water.
Environmental pollution is engulfing the whole world, so it remains a global concern. Pollution means ids ‘contamination of air, water, soil, etc. with unwanted fluids’, which have a direct effect on organisms and also have an indirect effect on ecosystems. In today’s context, thermal or thermal pollution is a real problem in modern industrial society.

You may have noticed that factories and industries use water from various natural sources to cool or heat large boilers and machines. When doing so, that water also becomes very hot or cold and then that water is again diverted to natural sources.
The release of more or less hot water into natural water bodies than normal temperatures affects the ecosystem; Which changes the level of oxygen in the atmosphere. Thus sudden change in the water temperature of natural water sources like lakes, ponds, wells, rivers and seas etc. for any reason is called thermal pollution.
Harmful effects of thermal pollution
Thermal pollution is very dangerous like other pollutants. Some harmful effects of thermal pollution can be:
- The release of hot water in natural aquatic sources leads to an increase in their average temperature, affecting the aquatic life there.
- The high temperature reduces the amount of oxygen dissolved in water, which initiates the process of anaerobic respiration. Due to which the number of bacteria starts increasing and thus aquatic life is affected.
- Due to hot water, not only bacteria, but also blue-green moss and many other types of moss grow. In this way, due to moss cover, various types of toxins are also formed in the water, due to which the quality of water deteriorates.
- After being used by factories etc., re-releasing hot water in aquatic sources leads to an unexpected sharp rise in water temperature. In this way, sudden increase in water temperature causes excessive loss of eggs, small insects, etc. of aquatic organisms. While low temperatures slow down organisms ‘lifestyles, high temperatures cause unusual fluctuations in organisms’ lifestyles.
- Rapidly changing water temperatures cause aquatic organisms to increase their metabolic rate as well as their physical activities. In this way, it also damages the food chain and affects organisms that are not directly related to water.
The conclusion
Actually, thermal pollution is not an unknown problem. The need is to understand it and find new ways to deal with it. Although human is not directly affected by this pollution, its indirect effect is cause for concern and concern. Therefore, there is a need to become sensitive to nature and natural resources and conserve them.
Apart from the development of technical measures, the framework of some other strong rules is also very important. Laws in this regard should be so effective that no factory can release its used water directly into water sources. Only then this problem can be dealt with.

Environmental pollution is engulfing the whole world, so it remains a global concern. Pollution means ids ‘contamination of air, water, soil, etc. with unwanted fluids’, which have a direct effect on organisms and also have an indirect effect on ecosystems. In today’s context, thermal or thermal pollution is a real problem in modern industrial society.
What is thermal pollution?
Thermal pollution is a process that reduces the quality of water and increases its ambient temperature leading to an increase in global temperature. This is due to the use of coolant water by various industrial plants such as thermal, nuclear, coal factories, oil-field generators, factories and mills.
In other words, after the use of coolant water by power plants and industrial manufacturers, when this water re-enters the natural environment, its temperature is higher, due to the change in temperature, the oxygen content is reduced. Causes ecology has bad effects.
What are the sources of thermal pollution?
- nuclear power plants.
- coal fired power plant.
- Industrial waste.
- domestic sewage.
- Hydro-electric power plant.
- thermal power plants.
Harmful effects of thermal pollution
The harmful effects of thermal or thermal pollution are discussed below:
- Dissolved oxygen deficiency: pollutants released from various industrial plants, such as thermal, nuclear, coal factories, oil field generators, factories and mills; Decrease oxygen concentration with increasing water temperature. Fish in the water require 6ppm (parts per million) to survive which cannot tolerate high water temperatures and may be on the verge of extinction.
- Changes in the properties of water: Changes in the temperature of water cause changes in the physical and chemical properties of water that affect aquatic flora and fauna. The rise in temperature affects the life of marine animals and vegetation begins to move out of that area. Many aquatic animals are on the verge of extinction in hot water.
- Increase in toxicity: The concentration of pollutants is a factor in increasing the temperature of water, which increases the toxicity of poison present in water which can increase the death of aquatic life.
- Interruption of biological activities: Temperature changes disrupt the entire aquatic ecosystem as changes in temperature can alter biological processes such as respiratory rate, digestion, excretion and growth of an aquatic organism.
- Biological organism damage: Aquatic organisms such as fish, plankton, eggs, larvae, algae, and protozoa are susceptible to death due to sudden temperature changes.
How can thermal or thermal pollution be prevented?
The following measures can be taken to prevent or control high temperatures due to thermal or thermal pollution:
Industrial submerged thermal water can be directly cooled by technology, convection, and radiation in man-made reservoirs before they are submerged directly into their water sources.
Revival of a process by which domestic or industrial excess heat is again reduced.
The conclusion
Therefore, we can say that any type of pollution can directly or indirectly affect humans because loss of biodiversity leads to changes affecting all aspects of the environment. Thermal pollution is a cause of concern and concern for people all over the world.

Thermal pollution is the degradation of water quality by any process that raises the ambient temperature. As the temperature is heated, the solubility of oxygen in the water decreases and thereby increases the metabolism of marine animals. Tropical marine animals usually survive at temperatures of 20 ° C to 30 ° C, and most sponges, mollusks, and crustaceans die at temperatures above 37 ° C.
Sources of thermal pollution
Industrial Waste:
A common cause of thermal pollution is due to the use of water as a coolant by power plants and industrial manufacturers. The main industries are-
- Hydro-electric power plant,
- coal-fired power plants,
- nuclear power plants,
- Industrial waste from the power, textile, paper and pulp industries.
Urban runoff
Urban runoff can have a significant impact on small water sources, as water flows through parking lots, roads and walkways for passers-by.
Domestic sewage
Municipal sewage also typically has a high temperature that goes through drains into the river and canals.
Effects of thermal pollution
Some of the main effects of thermal pollution are –
- Increased temperature usually lowers dissolved oxygen levels in water. A decrease in dissolved oxygen levels can harm aquatic animals such as fish and amphibians.
- As the enzyme activity of aquatic animals increases in thermal pollution, the rate of metabolism increases, as a result fossils start consuming more food in less time, which they would not have done if the environment had not changed. . Food is decreasing due to changes in metabolic process. In Australia, where many rivers have warm temperatures, indigenous fish species have been wiped out; Macro invertebrates have also changed considerably and are losing their power.
- There may be several reasons for the increase in metabolic rate. Similarly, those fish can also change their living areas and go to the places which are suitable for their habitat. In such a situation, it creates competition for the resources available in a small margin, with more adapted bacteria benefiting from them. Because of this, there is a compromise in the range of food available in the old and new environments. This condition can reduce biological variation.
- Lack of unnatural cold water in the reservoir can affect fish life. This reduces rivers, and river productivity.
- Physical and chemical properties of water are affected by toxicity and temperature increase.
- Many activities such as interference in fish breeding, nesting, harvesting, grass cutting, migration and breeding etc. depending on the favorable temperature. In such a situation eggs are destroyed due to lack of proper temperature.
- The increased vulnerability of the disease leads to high temperatures of many pathogenic microorganisms. A change in water temperature causes bacterial disease in fish.
- Thermal pollution allows it to invade organisms that are highly destructive.
- Many plankton, small fish and insect larvae are exposed to calm water, which is destroyed due to thermal pressures.
The conclusion
There are many ways to reduce thermal pollution. If hot water comes out of the condenser, heat pollution can be controlled by first passing through a cooling pond or cooling tower. Hot water is poured into the pond from one side and cold water is drawn from the other side. Heat is released from the pond and dispersed into the atmosphere. This heat is circulated in the air and then the water can be released into the river or reused for cooling in the plant. The use of cooling columns is another solution. Such structures occupy less space than the pond. Most of the heat here is transferred by evaporation.
