Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients.It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. [1]
Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife.
Eutrophication, a decline in oxygen content of water, of aquatic systems can cause the death of fish and other marine species. Finally, leaching of NO 3 from acidic sources can increase the loss of calcium and other soil nutrients, thereby reducing an ecosystem 's productivity.

[212] [225] [226] Dairy and fish and/or specific types of other foods and/or supplements contain omega 3, vitamin K 2, vitamin D 3, iodine, magnesium and calcium, many of which were generally lower in people consuming types of plant-based diets in studies, [227] [228] though meat-eaters were also shown to be at risk of nutritional deficits.
Fish populations, the main source of protein and overall life support systems for many communities are also being threatened [6] reduced discharge into the sea, which may have various consequences like coastal erosion (e.g. in Ghana [ 7 ] ) and saltwater intrusion in delta's and estuaries (e.g. in Egypt , see Aswan dam ).
At the Bay Shore Power Plant in Ohio, 46 million fish were killed over an 18-month period. [3] [7] Organisms that pass through the screens are killed or stressed (depending on the species) as they become entrained in the cooling system. [4] 208 million fish eggs and over 2 billion small and larval fish were entrained at the Bay Shore plant over ...
Water management is the process of planning, developing, and managing water resources across all water applications, in terms of both quantity and quality." Water management is supported and guided by institutions, infrastructure, incentives, and information systems [39] The issue of the depletion of fresh water has stimulated increased efforts ...
