'''Thermal pollution''' is the rise or fall in the temperature of a natural body of water caused by human influence. 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 change in temperature impacts organisms by (a) decreasing oxygen supply, and (b) affecting ecosystem composition. Urban runoff--storm water discharged to surface waters from roads and parking lots--can also be a source of elevated water temperatures
the advantage is that the plants can give out more oxygen in day time .may be we will be healthy. the disadvantage is that our surrounding may be polluted and not clean.
It is caused by addition of hot effluents and hot water bodies. Warm water contains less oxygen. So there is decrease in rate of decomposition of organic matter. Green algae are replaced by less desirable blue green algae. Many animals fail to multiply. Trout eggs fail to hatch while salmon does not spawn at higher temperature.
hydrogen, oxygen, and temperature
The atmosphere in large cities can be affected by thermal pollution due to vehicle exhausts and buildings being close together, also due to a large amount of heating in winter and air conditioning in summer, so large cities tend to be warmer than the surrounding country areas. Close to power plants, rivers and lakes can be thermally affected by the plant cooling water.
Trees produce oxygen. If the tree is cut down, it will no longer produce the oxygen that the ecosystem needs. So when we cut down trees, less oxygen is being produced, and the less oxygen produced, the more uneven the balance of pollution and oxygen.
Thermal pollution results from adding heated water to a watercourse. Thermal pollution encourages the growth of some aquatic organisms over others (e.g. trout need colder water than carp) and reduces the oxygen content of the water so that only more resistant life forms can live in the water.
First it's Thermal Thermal pollution is a temperature change in natural water bodies caused by human influence. The temperature change can be upwards or downwards. In the Northern Hemisphere, a common cause of thermal pollution is the use of water as a coolant, especially in power plants. Water used as a coolant is returned to the natural environment at a higher temperature. Increases in water temperature can impact on aquatic organisms by (a) decreasing oxygen supply, (b) killing fish juveniles which are vulnerable to small increases in temperature, and (c) affecting ecosystem composition. In the Southern Hemisphere, thermal pollution is commonly caused by the release of very cold water from the base of reservoirs, with severe affects on fish (particularly eggs and larvae), macroinvertebrates and river productivity.
The amount the organism within a community, particularly in an aquatic community, demend oxygen. Eutrophication can cause the demand to rise and harm the fish within the aquatic ecosystem.
Because thermal pollution increases water temperature, so decreasing oxygen availability for the organisms in the lake.
Warm water holds less oxygen
eutrophication. This can lead to excessive growth of algae and other aquatic plants, which can deplete oxygen levels in the water. This depletion of oxygen can harm fish and other organisms, leading to a decline in biodiversity and, in some cases, the complete collapse of the ecosystem.
Cold water can hold more dissolved oxygen than warmer water.
Some changes that can occur in the aquatic ecosystem as a result of nutrient loading is called algal bloom. This is where there is a rapid increase of growth of phytoplankton which causes dead zones. These dead zones consume too much oxygen where plants and sea life can no longer survive in these areas.

It affects the oxygen level because it is essential for the survival and growth of organisms ata ll levels within its ecosystem.
It decreases the dissolved oxygen in the river water Answer: Thermal (warmer water) pollution:* Lowers the oxygen saturation point of the water making it less desirable for non tolerant species (Carp flourish, trout don't) * Promotes the growth of slimes and molds * Changes the rate of decomposition * Prevents breeding of some fish species * Changes the benthic population * Promotes overwintering of some bird species
