Thermal Pollution & Causes
Thermal Pollution is the degradation of water quality by any process that changes ambient water temperatures and divulges it from the normal or preferred temperature conditions. Usually it is associated with the rise in the temperature of the water bodies which might either be a stream, lake, river or an ocean. It happens due to the discharge of heated water from industrial processes like generation of electricity in thermal power plants. The increases in the ambient temperature might also happen in streams which can be associated with the removal of shading vegetation along the banks or with sedimentation making the water body even more turbid. These effects allow more energy from the sun to be absorbed by the water

The reason being that these plants draw water from nearby source to keep machines cool for their proper functioning. After that the water is then released back to the source which has considerably higher temperature than usual. This water with increased temperatures when is released to the natural sources of water bodies the water temperature rises sharply. This alters the oxygen levels in the water. When the amount of oxygen present isn’t enough it hampers and degrades the quality and longevity of life of the marine and aquatic animals living and surviving underwater. This process has the capability of wiping away the streamside vegetation, which depends on the constant levels of oxygen and temperatures. When these natural conditions are altered it leads to heavy disruption of the proper functioning. Industries are helping in decreasing the quality of life for these marine based life forms. They ultimately end up destroying habitats if they are not controlled and they don’t check their current …show more content…
They prevent sunlight from falling directly on the lakes, ponds and rivers. Thus due to deforestation these water bodies are then directly exposed to solar radiation. They end up absorbing more heat and consequently their temperatures raises.
• Runoff from Paved Surfaces – there is a considerable amount of urban runoff which has been acting as a causal phenomenon for thermal pollution. Urban runoff is discharged to the surface waters from paved structures like roads and parking lots has the capability to make the water warmer when drained to them. Mostly during summer seasons, the pavements get really hot. This creates warm runoff that gets into the urban sewer systems and then finally drained into the water bodies.
• Soil Erosion – Soil erosion is equally responsible for thermal pollution. Consistent soil erosion has lead to the rise of the water levels in the water bodies exposing and making them more susceptible to sunlight. The high temperature could prove fatal for aquatic biomes as it may give rise to situations and anaerobic
They also look after the quality of coastal waters by watering down, sifting, and settling deposits, left-over nutrients and contaminants. They are highly productive ecosystems and provide habitats and act as nurseries for all manner of life.
When the sun heats the Earth gases are released as well as water vapor. They go into the atmosphere and regulate the temperature. This is known as global warming or the greenhouse effect. Many of the environmental complications derive from the political and social involvement. The climate was not the only cause, but we had humans played a role on what had been occurring to the world. Earth has many different atmospheric layers that are influenced by the greenhouse gases. “Atmospheric concentrations of carbon dioxide have now increased nearly 30 percent since the beginning of the Industrial Revolution; methane levels have more than doubled; and nitrous oxide concentrations have risen by about 15 percent” (Fagan 209). The increase of these gases also enhanced the trapping of the heat. With more heat being trapped this lead to many coastlines to flood due to the melting of snow and ice. The increase of dangerous weather actions will pose as a threat also. These changes in the environment would eventually lead to political and social change of the people Overpopulation in certain areas and industry formation influence the greenhouse effect. We as a whole are destroying the place we live, the natural world. Although there are ways to prevent and reduce global warming, we cannot stop the natural occurrence of future climate. Climate is not the only factor, each individual that as
greenhouse gases emitted in its creation as well as use, and pollutants that cause acid rain, smog,
Decreased water quality, increased pollution and depletion of natural resources are direct results but there are secondary effects that are a part of a series of actions and reactions(seatlepi.com). The impact of human activity can most easily be observed through our water and one of the biggest impacts on water is excess nutrient inputs from the overuse of fertilizers globally and from oil and chemical spills and dumping regionally. The majority of air pollution comes from fossil fuel combustion from vehicles including airplance, factories and power plants.
water quality. When the water temperatures rise, the winter ice start to melt, and that
However environmental impacts will differ depending on the conversion and cooling technology used. Firstly geothermal plants can have effects on both water quality and consumption. Hot water pumped from underground reservoirs often contains high levels of salt, sulfur and other minerals. Air emissions in a open-looped system emit boron, ammonia, carbon dioxide, hydrogen sulfide and methane which will also have a harmful impact on the environment. Furthermore hydrogen sulfide changes into sulfur dioxide once in the atmosphere. This harmful gas contributes to small acidic particulates that can be absorbed by the bloodstream and cause heart and lung disease. This gas is also aids in creating acid rain, which in turn damages forests, soils and crops, and acidifies streams and lakes. Land subsidence, which is caused by the removal of water from the geothermal reservoirs can also have a colossal effect on the
One of the main causes of climate change is the massive amounts of greenhouse gases, especially carbon dioxide that is being released into the air. This causes pollution in the air and, subsequently warms the Earth. By the end of the century, Earth is expected to raise about 2 degrees (Adams). The implications of a global pollution are potentially disastrous; industrialized cities and cities with high traffic are set for massive negative
According to World WildLife Fund, many ecosystems around the world are being destroyed, eliminating many plant and animal species that inhabit them (“Pollution”). 2. And acid rain, which is created when water in the atmosphere mixes with chemicals, ravage through rain forests and can even kill fish. 3.
Pollution is causing the destruction of environments and habits resulting in many adverse affects. The types of environments that are heavily damaged by pollution is normally freshwater ones. Polluting factors such as untreated sewage, mining waste, acid rain, fertilizers and pesticides
ü AIR POLLUTION- Sulphur dioxide from burning fossil fuels leading to acid rain, carbon dioxide from burning of fossil fuels and methane from cattle and rice fields leading to greenhouse effect and global warming. ü LAND POLLUTION - pesticides, herbicides, and nitrates wash into rivers and lakes affecting food chains. Habitat reduction by Humans = ==
They also purify the air we breathe and water that we need to survive. Deforestation by humans is causing these functions to be lessened and damaging the atmosphere even further. (www.climateandweather.net) Deforestation is one of the major factors contributing to the greenhouse effect and desertification

Global warming is one of the major reasons in marine pollution. For an instance in the year 2010 there was an oil leakage near Mumbai in the Arabian Sea.
Water pollution is very harmful to the environment and living things. Water pollution can come from many different sources. If the pollution comes from only one source, such as an oil spill, it is called point-source pollution. If it comes from many different sources, it is called nonpoint-source pollution. Most water pollution affects the immediate area surrounding the source, but there are some types of pollution, such as hazardous, that can affect areas miles away from the source. Water pollution is something that can be prevented; it is important to be aware of the causes of water pollution to keep the environment safe and clean for the many generations to come.
Water pollution is also a major thing in the world because almost 60% of it is fishes. It occurs due to several factors; the industrial waste dumped into the rivers and other water body’s cause am imbalance in the water leading to its severe contamination and deaths. And the infamous Global warming is the emission of greenhouse gases particularly CO2 is leading to global warming.
