Water, water everywhere and not a drop more. This is the reality, especially regarding the amount of fresh water available. Fact: Earth contains only 3.5% fresh water. Fact: 98.8% of all fresh water is protected from our reach in glaciers or aquifers. Fact: Only 0.0003% of the earth's water is accessible for consumption. With such a small amount of fresh water available, the high amount of pollution contaminating this water is appalling. Water quality levels are declining, harming us and the countless organisms that depend on freshwater habitats to become safe homes. One of the major contaminants, nitrates, which come mainly from man-made sources, are particularly dangerous… Many people are unaware of the impact of nitrate ions in freshwater habitats. The presence of nitrates is essential for the growth and development of plants. This is because nitrogen is a key ingredient in the nucleic acid structure of plants. The natural level of nitrate concentration in fresh water is 1 milligram/liter (mg/L). However, due to agricultural activity, these levels are rapidly increasing. Increasing levels of nitrate are shifting the balance of freshwater habitats. The typically gradual rate of eutrophication (the dramatic growth of plants and algae) is accelerating due to too much of this nutrient. Due to eutrophication, algal blooms, i.e. groups of algae, form on the surface of the water. These clusters of algae block sunlight from reaching other aquatic organisms beneath the water's surface. Additionally, eutrophication distorts dissolved oxygen levels and causes hypoxia (lack of oxygen). The solution to preventing excessive buildup of nitrates in freshwater bodies is to cut them off at the source… in the middle of the paper… in the watershed. The world is filled with a multitude of places that contain the proper geography for building wetlands. All that remains to be done is to implement these habitats globally. The implementation of constructed wetlands globally is completely feasible. The low construction and operating costs of CW make it a cost-effective solution. Habitat management requires much less attention than other nitrate desalination procedures. As long as we fulfill our duty and avoid leaving waste in these habitats, wetland productivity will remain high. CW provides the perfect solution to dispose of excess nitrates cleanly and naturally. Furthermore, countless forms of biological life may depend on chemical warfare to provide safe housing. Through the power of constructed wetlands, freshwater habitats will thrive and thrive for future generations.Works Citedgoogle.com
