It is therefore highly important to devise methods to reduce the level of water pollution that we are currently facing. Causes, Effects and Control. New Age International, Rely on professional writers with your college paper and take a load off your mind.

Among such industry-related problems as air pollution, soil contamination, radioactive waste, and so on, the problem of low-quality water stands as one of the most pertinent in terms of its importance for the survival of humankind.
Therefore, information about the negative effects of water pollution should be not only studied, but spread among the general populous, taken into consideration, and prevented. One of the most significant problems connected to poor water quality is that entire food chains are drastically affected or even become extinct due to increased toxicity. Such pollutants as lead or cadmium get into water, and contaminate microorganisms living in it.
These microorganisms are consumed by larger species—such as plankton—which, in their turn, are eaten by even larger animals, and so on. Eventually, this chain leads to human beings, because people all over the world consume fish and seafood. Thus, by polluting oceans, people worsen their overall well being ESchoolToday.

An ecosystem is the way of interaction between creatures that inhabit a certain area, and thus depend on each other.
But, water pollution can severely damage the subtle connections between the living species inhabiting certain environmental areas ESchoolToday. This, in its turn, leads to an increasing imbalance in the environment, causing species to become extinct; every time an ecosystem suffers, it also affects the condition of our planet in general, and thus, people living on it.
Perhaps the most significant damage from water pollution is connected to humans. For instance, diseases like hepatitis are caused by eating contaminated seafood; developing countries, which often have problems with the quality of water, experience frequent outbreaks of cholera or diphtheria. Water is also present in the atmosphere in solid form in the polar icecaps and as groundwater in aquifers water-bearing rocks deep underground. Water has many remarkable properties. It also acts as a fluid medium facilitating the dispersal of un-dissolved particulate matter.
Water pollution may be defined as any chemical or physical change in water detrimental to living organisms. It can occur through natural processes, for example by sediments produced by natural erosion. Water bodies are a major recipient of an extensive array of wastes produced by human activity. These may be discharged directly into watercourses by sewers or pipes from factories or be washed down from agricultural or urban areas particularly after heavy rains.
Under rather exceptional circumstances, water bodies may become significantly contaminated by the atmospheric deposition of pollutants. Water pollution is a global problem and one that does not respect national boundaries. Sources of pollution may be domestic, agricultural or industrial.
In less-developed countries, human and animal waste and sediments from unsound agricultural and forestry practices are the main pollutants.
In more-developed countries; industrial pollutants, such as toxic metals, organic Chemicals and heat add to the water pollution problem. The effectiveness of treating wastes prior to their release into the environment determines the balance between potential and actual pollution. The release of large quantities of oxygen-demanding organic waste into watercourses often has disastrous effects on the indigenous flora and fauna.
The primary source of organic waste released into fresh waters is sewage effluent. Other sources include run-off from urban areas and farms, and some industrial effluents. The recent intensification of livestock production, with larger herds concentrated in smaller areas, has exacerbated the problem of organic pollution from farm animal wastes.
Aquatic primary productivity is often limited by the availability of inorganic plant nutrients. In freshwater lakes and rivers, the limiting nutrient element is usually phosphorus, whilst in marine waters nitrogen is often in short supply.
If small amounts of nutrients enter aquatic ecosystems where they are normally limiting, primary productivity is stimulated.

Water pollution is one of the world's worst forms of pollution. For example, take a look at a glass of water. It may appear clear, but there are really millions of microscopic pollutants floating in it. Approximately 70% of the earth's surface are covered by water; water is a very dynamic system 3/5(10).

Water Pollution essays Water pollution has been an increasing problem over the last few years. Pollution itself is when a substance or energy is introduced into the soil, air, or water in a concentrate.
Water pollution, like other types of pollution result when an overwhelming amount of waste comes from different sources of pollutant which harmfully disrupts the balance of the ecosystem; consequently, the waste cannot be destroyed or cleaned up as quickly as produced which results in many disadvantageous to humans and animals, as well as other living organisms. Essay on Water Pollution Water covers two-thirds of the Earth’s surface, with over 97% present in the oceans and less than 1% in freshwater streams and lakes. Water is also present in the atmosphere in solid form in the polar icecaps and as groundwater in aquifers (water-bearing rocks) deep underground.
