When thermal pollution happens, the water temperature in streams, rivers, lakes, or oceans changes. It is one of the most serious types of pollution.

Thermal pollution can have many different causes. Power station are one factor. They use water in the nearby lakes or rivers to cool their equipment, which heats up the water. Then they dump the hot water back into its source. Thermal pollution may also happen due to the discharge of cold water from reservoirs into warm rivers.

Thermal pollution can have dramatic effects. Most aquatic creatures need a certain temperature to survive. Warmer water has less oxygen in it, and this can harm fish populations. Besides, warmer water can cause harmful algal blooms. This can change the colour of the water like in the first picture and, more seriously, the algea poisons the fish.

So, in many places, we build cooling towers like in the second picture to cool down the water from power stations.

Thermal pollution is the degradation of water quality by any process that changes ambient water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the sudden change in temperature decreasesoxygen supply and affects ecosystem composition. Fish and other organisms adapted to particular temperature range can be killed by an abrupt change in water temperature (either a rapid increase or decrease) known as "thermal shock."

Urban runoff—stormwater discharged to surface waters from roads and parking lots—can also be a source of elevated water temperatures.

Because of thermal pollution, apatic life sudders or diers.

Definition: Thermal pollution is the degradation of water quality by any process that changes ambient water temperature.

Causes : A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the sudden change in temperature decreases oxygen supply and affects ecosystem composition.

Effects: The Effects of Thermal Pollution on Marine Life.Thermal pollution occurs when power plants and factories discharge hot or cold water into nearby rivers, lakes, streams, oceans or bays, causing rapidly changing water temperatures.

Solution:

Shade trees around waterways and coastal locations help to lower temperatures by blocking the sun’s rays and absorbing carbon emissions. This prevents the water from heating to abnormal temperatures. We could also achieve the same effect by not harvesting shade trees.

Because power plants are a major contributor to thermal pollution, one simple solution to implement is to use less power. This would require less water to be used as coolant, which would reduce the heated water being sent back to the same body of water from which it had been acquired.

Another major source of thermal pollution is water runoff from hot concrete, asphalt, and similar surfaces. By taking another look at city planning and working to normalize these temperatures, we could help to reduce the harmful temperatures that occur during the hottest months of the year.

Another source of thermal pollution is soil erosion. When top soil goes away, it reduces the amount of filtering that the ground naturally provides. By changing our farming methods to a more sustainable no till method, we can still achieve similar yields while continuing to maintain the planet’s natural processes to reduce thermal pollution issues.

Many homes use heated water as a source of power. It is currently processed through solar panels or a similar system, but we could also recycle the artificially heated water for power in other ways in a secondary process.

Thermal pollution cannot be overlooked as a potential threat to the environment. These solutions are just a few of the ways we can get started on the restoration process today.

Industries that use large amounts of water as coolant, for example in power plants, steel industries, smelters, paper and pulp mills and chemical plants, release the heated water into nearby water sources without first cooling it appropriately

In cities that are covered by concrete and other man made materials in most parts are also causing thermal pollution. The streets, parking lots and other covered spaces are heated up by the sun. When rain or storm water falls on them, it absorbs the heat and runs of into the drains. This water is sometimes up to 10 Degrees warmer than the surrounding water. When untreated and allowed to flow into rivers seas or oceans, it causes thermal pollution in these waters.

Like the anecdote mentioned above there are ecological disturbances that occur when the temperature of water is increased.

Thermal Shock

When there is an abrupt increase in the temperature of the water this leads to sudden death of all the fish and other organism in the water which are adapted to a certain temperature. This is called thermal shock. This is noticed when a power plant or an industry starts functioning for the first time and also when it has opened up after a break for repairs.

Heated water from industries can be treated before being released into the nearby water bodies. There are various mechanisms developed for this.

Conclusion

Though it may appear that thermal pollution may not affect humans directly, it is not true. Loss of bio diversity causes changes that affect all the aspects of the environment, because nothing is independent and no one survives completely on their own without relying on their environment.

There is the obvious effect on the food chain, where even now sea food collection has decreased dramatically, irrespective of all the food shows on TV which encourage massive consumption of a depleting food source.

Watching fish in an aquarium is a very effective relaxation therapy. Having a picnic by the river or lake is very invigorating. Listening to the buzzing of insects and the croaking of a watchful frog is companionable. Watching friendly dolphins leaping out of the water and grinning comically is very rejuvenating and inspiring.

Desiring to preserve the integrity of our environment is not selfish and planning and moving in this direction is the right thing to do.
