government to carry out these investigations. Strict action must be taken against them if they To minimize the presence of phosphate and nitrate in the water bodies, people should substitute nitrate and phosphate fertilizers with compost manure. The toxic compounds can also go up the food chain through bio-accumulation and bio-magnification, causing other health complications like cancers. If the demand for oxygen is very high, it could outstrip the supply making it difficult for fishes and aquatic organisms to survive in the water bodies. Cultural eutrophication or nutrient over-enrichment, especially of nitrogen and phosphorus, has degraded many coastal waters and has been invoked as a major cause of seagrass disappearance worldwide (e.g. Use of fertilizers on farmlands that are washed away from soil into rivers and lakes. Fertilizers. Algae fouls the water and air. Concentrated animal feeding operations are characterized by high discharge of artificial nutrients into rivers, lakes, and oceans. Besides, the algal blooms are highly toxic. Governments should create laws and policies against non-point pollution. The process is characterized by excessive plant and algal growth in the water bodies. unwanted organic compounds and bad undesirable odor. A good scenario of how human activities affect the ecology of water bodies is when humans dump sewage into water bodies. 1998). As more and more organic matter accumulates, the demand for oxygen from the water increases until there is no more dissolved oxygen to support the algae. Eutrophication poses a problem not only to ecosystems, but to humans as well.Reducing eutrophication should be a key concern when considering future policy, and a sustainable solution for everyone, including farmers and ranchers, seems feasible. They can also limit the mobility of boats and other fishing vessels. Eutrophication is most often the result of human activity. When water bodies are overly enriched with these nutrients, the growth of algae, plankton, and other simple plant life is favoured over … Any pollutants that get phosphorus and nitrogen into the water. Other technologies that convert plant growth present in water bodies into energy have also been advanced. reduce their numbers within the water. They are responsible for the addition of 80% nitrogen and 75% phosphorus to lakes and streams. ecosystem to survive and respire. Fertilizers, used in farming to make soil more fertile, contain nitrogen and phosphorus. The modern method of rearing fish, shellfish, and growing aquatic plants without soil is also becoming a big contributor to cultural eutrophication. Eutrophication most commonly arises from the oversupply of nutrients, most commonly as nitrogen or phosphorus, which leads to overgrowth of plants and algae in aquatic ecosystems. nitrites. Over the last few years, tech developers and scientists have been working towards creating technologies that can help reduce pollution and even reverse the damages already caused. 13437 shares The soil eutrophication is caused when the wastes containing nitrates and … Compost manure does not contain high elements of nitrates and phosphates that cause eutrophication. the detergents. The term refers to an increase in nutrients, especially phosphorus and nitrogen, resulting in an explosive increase of alga – the algal blooms. carried out, and can be improved upon are: Scientists and Environmentalist must carefully monitor the quality of fresh water in Eutrophication derives from the Greek word eutrophos, meaning nourished or enriched. It is categorized into two including natural and cultural eutrophication. The oligotrophic water bodies have a rich supply of oxygen, unlike the algae rich eutrophic water bodies. A common characteristic of eutrophication is the explosive growth of phytoplankton and other plants. Algae and cyanobacteria make the water almost impossible to thrive and grow sufficiently to degrade the algae. - "The Globalization of Cultural Eutrophication in the Coastal Ocean: Causes and … Eutrophication increases the growth of algae and minute plants as well as photosynthetic bacteria. In short it alters the The concept of cultural eutrophication is particularly brought about by a human understanding that clear water with minimal visible organisms is better than organic-rich water. Detergents which contain high amount of phosphates should Abundant plant growth produces an undesirable disturbance to the balance of organisms and the quality of water. Dumping untreated sewage into a water body, for example, results in the fertilization of the algae, increasing their growth. (And 9 Ways to Reuse Wallpapers), Are Juice Cartons Recyclable? The algae having so many potential factors for its growth, Top Environmental Issues We Are Facing Right Now. leading to eutrophication even with prior knowledge of its consequences. Even if we are assured that the water coming from the Excessive phosphates may be removed by the addition of salts Cultural eutrophication is the process that speeds up natural eutrophication because of human activity. needed for photosynthesis are available in significant quantity to cause excess Cultural eutrophication has had dramatic consequences on freshwater resources, fisheries, and recreational bodies of water and is one of the leading… Desertification: Process, Causes, Effects, Solutions, 10 Dangerous Effects of Smoking Cigarettes on Human Health as well as the Environment. The most noticeable problem with eutrophication is the deterioration of water quality. systems available so they may work more efficiently in reducing the unwanted Cultural eutrophication is the process that speeds up natural eutrophication because of human activity. When trees are cut, soil erosion occurs, which carries the sediment and other nutrients into water bodies creating a suitable environment for the explosive growth of algae blooms. the water further depleting the oxygen concentration. this regard. Educate the masses and raise awareness regarding cultural Although this is a slow process, it may be increased with the addition of human pollution which is called “Cultural Eutrophication “. Cultural eutrophication causes major changes in the water with the addition of excess amount of nutrients; mainly phosphate and nitrates. After such organisms die, bacterial degradation of their biomass results in oxygen consumption, thereby creating the state of hypoxia. This This is where I tell you about the Process of Cultural Eutrophication. of aluminum, iron or calcium carbonate which form compounds of phosphates which (And Can You Compost Them), Eutrophication is a major environmental concern. High nitrogen concentration in drinking water can also inhibit blood circulation in infants. Effects of cultural eutrophication. Improvements must be carried out in the water treatment The bacteria generate a red tide that releases very powerful toxins with high poison levels into the water. Eutrophication is a serious environmental problem which Raising awareness, not locally but globally, was the mission. If aquiculture is not properly managed, food particles and fish excretion can find their way into water bodies, creating a good environment for dense growth microscopic floating plants. how their actions can help prevent eutrophication. There are three main sources of anthropogenic nutrient input: erosion and leaching from fertilized agricultural areas, and sewage from cities and industrial waste water. Causes of Eutrophication Natural run-off of nutrients from the soil and the weathering of rocks. Humans prefer clear water as opposed to nutrient-rich water. Increased photosynthesis activity causes a dense growth of algal blooms and other plant species. Eutrophication of freshwater bodies causes loss of earth’s biological resources and aggravates climate change, thus assuming major environmental concern. Fertilizers that contain phosphorus and nitrogen. Mostly, eutrophication leads to easily detectable algal blooms which turn the water green in color as there are numerous amount of algae situated on the surface of the water. Recent coastal surveys by the United States and the European Union found that 78% of U.S coastal waters and 65% of Europes Atlantic coastal waters exhibit symptoms of eutrophication. FIGURE 2 | Global distribution of eutrophic coastal marine ecosystems (adapted from Breitburg et al., 2018). The poison can cause death to humans and animals if ingested at the least concentration in drinking water. Eutrophication is predominantly caused by human action. Man-made causes (Cultural eutrophication): This process is generally speeded up by human activities. The European Union defines cultural eutrophication as The enrichment of water by nutrients, especially compounds of nitrogen and phosphorus, causing an accelerated growth of algae and higher forms of plant life to produce an undesirable disturbance to the water balance of organisms present in the water and to the quality of the water concerned, (European Commission, 1991). Overgrazing Deforestation Agricultural techniques Water management…, Cigarette smoking causes natural contamination by discharging lethal air pollutants into the air.
