The conservation of water is extremely important in order to preserve wildlife habitats. There are many organisms in temperate regions who are affected by shortages in water. [12] Additionally, many freshwater organisms are increasingly feeling the impacts of water pollution as it disrupts the ecosystem. [12] "World Water Day" is celebrated on ...
Nutrient pollution caused by Surface runoff of soil and fertilizer during a rain storm 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 ...
A 2006 measurement of pollution in the Ganges revealed that river water monitoring over the previous 12 years had shown fecal coliform counts of up to 100,000,000 MPN per 100 mL [29] and biological oxygen demand levels averaging over 40 mg/L in the most polluted part of the river at Varanasi. The overall rate of water-borne disease incidence ...
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
In 2005, economic losses (mainly from air pollution) were calculated at 7.7% of China's GDP. This grew to 10.3% by 2002 and the economic loss from water pollution (6.1%) began to exceed that caused by air pollution. [18] China has been one of the top performing countries in terms of GDP growth (9.64% in the past ten years). [18]
Relevant issues include water scarcity, water pollution, inadequate water supply, lack of sanitation, and the impacts of climate change (which is the theme of World Water Day 2020 [10]). The day brings to light the inequality of access to WASH services and the need to assure the human right to water and sanitation.
