Elevated temperature typically decreases the level of dissolved oxygen DO in water. The decrease in levels of dissolved oxygen DO can harm aquatic animals such as fish, amphibians and copepods. Thermal pollution may also increase the metabolic rate of aquatic animals, as enzyme activity, resulting in these organisms consuming more food in a shorter time than if their environment were not changed.
An increased metabolic rate may result in fewer resources; the more adapted organisms moving in may have an advantage over organisms that are not used to the warmer temperature. As a result one has the problem of compromising food chains of the old and new environments. Biodiversity can be decreased as a result. Three main types of inputs of pollution into the ocean are direct discharge of waste into the oceans, runoff into the waters due to rain, and pollutants that are released from the atmosphere.
Pollutants enters into to the oceans are mostly diluted; however the organisms living in the oceans tend to concentrate the pollutants into their body by various mechanisms, like adsorption, absorption, ingestion etc. The concentration of pollutant increases with higher tropic levels, i. The threshold limit of organisms to the pollutant concentration increase with increasing tropic levels. Various mode of pollution transport in organisms includes bioconcentration, bioaccumulation and biomagnifications.
Water pollution also leads to Large scale death of aquatic and terrestrial animals, Reduced reproduction rate, Increased incidence of diseases, Imbalances created in secondary food chains, Accumulation of bioaccumulative and non-biodegradable pollutants in animal bodies, Some organochlorine pesticides like DDT, BHC, Endrin are known for bioaccumulative and biomagnifiable characters. The contamination of water bodies has tremendous negative impact on environment, it has ability to destroy many animal habitats, and cause irreparable damage to many ecosystems.
Water pollution is not only killing millions of people around the globe each year, it is also killing millions of plants and animals that simply cannot cope with the increasing levels of water pollution caused by different chemicals and other waste. In some areas of the world water pollution issue is totally out of control, and in these areas polluted water spreads different toxins and other chemicals into environment, making it dirty, and above all unhealthy place to live in.
Among the most common causes of water pollution include the pathogens, various chemicals or other contaminants as well as other thermal sources of pollution. Pathogenic causes of pollution in water are usually the bacteria as well as other microorganisms that are commonly food in the surface of the water. If their population exceeds the normal rate, then its effects would be adverse to the human health. Of course, the chemical sources of water pollution include those from detergents, disinfectants, food processing wastes and many more.
Water pollution can also leads to various diseases like vomiting or diarrhea, sick stomach, skin rashes, Cancer.

GAP concentrated on improving the water quality of Ganga, in terms of organic pollution and dissolved oxygen. Connections of household toilets to the sewer system, solid waste management, and some other vital aspects of municipal activities, which impinge on the water quality were not addressed. The issue of ensuring environmental flows in the river was not attended to. This has become increasingly important in view of the competing demands on the Ganga water for drinking, irrigation and power generation.
Adopting more efficient water conservation practices could have reduced the need for abstraction of water from Ganga. Tree cover in the Ganga basin has reduced considerably and land use pattern has changed leading to soil erosion. Sediment yield and its deposit on the river bed were also not monitored. Only Class-I towns on the banks of rivers were taken up.
Thus a large number of urban settlements remained outside the purview of the Plan. Several parameters such as heavy metals, pesticides, nitrogen and phosphorous were not monitored. These parameters have become important with increased industrialization and urbanization. Commercial activities in the vicinity of Gangotri say within m to be transformed into eco friendly activities. Plan for environment protection and preservation of natural and pristine conditions e. Harshil to be developed as nature friendly, zero waste terminal pilgrim tourist spot with facilities of ashrams, guest houses, parking, internet, etc.

Hydroelectric plants are built in rivers for the creation of electricity. Various dams are also created for harnessing electricity such as the Bhakra Nangal Dam. Rivers also help in improving the economy of a country. This is because they help in transportation of goods from one place to another.
Import and export of goods in turn improves the economy of a country.
