CONTROLLING THE RISK: As we can see the sources and how the water is being contaminated we can know how this can impact the world. With the pollution the rate of unadulterated drinking water is diminishing quickly. Numerous individuals are getting debilitated because of drinking this water. The natural framework is being hurt by this as the species living water are biting the dust. Due to the water pollution a wide range of sorts of fishes which we used to discover in past are not discovered today.
Nutrient pollution coming from agricultural runoff and other fertilizers allows for the growth of species that upset the balance of the ecosystem such as Cattail, harmful algae bloom, and duckweed. The sulfur in the agricultural fertilizers leads to accumulation of toxic mercury in fish, birds, and mammals. Also, exotic animals or invasive species displaced native and threatens to disrupt the ecosystem balance. The purpose of this experiment is to determine how the water quality affects the Everglades ecosystem and how water pollution impacts different species. Urbanization is a big threat that contributes to poor water quality in water pollution.
Consumer surveys have shown that evidence is mixed on whether people perceive aquaculture as giving rise to environmental and animal welfare problems, and it differs among countries and regions. In Europe, the focus on environmental risks associated with fish consumption is most pronounced in the northern and western countries, such as Belgium, Denmark, Finland, France, Germany, Ireland, the Netherlands, Norway, Sweden and the United Kingdom (EC, 2008). In Norway, the public was found to be especially aware of environmental topics, owing to the particular importance of the aquaculture industry to their country (Schlag and Ystgaard, 2013). Interestingly, in Germany, overfishing raises more sustainability concerns than does fish farming. Thus
Water pollution is a very prevalent problem throughout the world. It affects ecosystems, deters the natural food chain, and can cause disease in both animals and humans. But is water pollution affecting natural lakes and ponds in local areas? In this experiment, Daphnia magna will be used in a bioassay to find if water from local areas is habitable for aquatic organisms. Daphnia magna are small freshwater invertebrate organisms.
Agriculture immensely adds to the nutrient and chemical pollution due to the fertilizers used on crops. When rains or winds come through the fertilizer is carried from the fields into the rivers and streams that then lead into the ocean(Effect of Runoff). Red tide had been a huge issue that is unpreventable and caused by dinoflagellates (Red Tide). Red Tide is a type of algal bloom that takes up oxygen in the water. When the oxygen levels in the ocean are lowered it can kill many plants which is very unfortunate for the manatees considering they are herbivores and with their food supply being depleted they may suffer from starvation.
The excess nutrients may induce pathogen and provide the elements required by the pathogen to proliferate or become directly toxic to the coral making them more susceptible to the disease.The imbalance in the exchange of nutrients between the zooxanthellae and the host coral reduces light penetration to the reef due to nutrient-stimulated phytoplankton growth, and, most harmful of all, may bring about proliferation of seaweeds (Dubinsky, 1996).Nevertheless, the study had discovered that the coral capable to recover and revive once the nutrients supplies stopped. Last but not least, various chemicals of pesticides and fertilizers from agriculture practices are flowing into the water cycle via soil infiltration and surface run-off. One of the most critical threats
How to mitigate the problem of damn impoundment to Tor sp Dam impoundments create barriers across rivers that gives negatives impacts on natural fish populations. The dam impoundment can contribute to the disappearance and exticntion of species and also diminished abundance. Tor sp is one of species affected by dam impoundment. Mitigation measures are really need to prevent the problem from arise. A) Construction of fish passage There are three ways of fish migrations.
Nevertheless, several process enhancements in MSC-certificated fisheries and one notable ecological improvement became evident. The ecological improvement was direct related to the certification process and accomplished with a view to the assessment process: the seabird by-catch in the South Georgia Patagonian toothfish was reduced. Moreover, other researchers found out that the certifications requirements of the MSC seem to favor small-scale fisheries and large-scale fisheries in developed countries. Small- scale fisheries have the advantage that because of their limited access, it is easier to certify them. The process of certification is time devouring, expensive and challenging.
Next there are damaging effects that could cause problems with the body such as diarrhea, sickness, or even death. The environment of that whole town would be impacted by the water and animals will also experience the effects of it. “The major concern for surface-water quality is the promotion of algae growth (known as eutrophication), which can result in decreased oxygen levels, fish kills, clogged pipelines, and reduced recreational opportunities.” (Turk & Bensel, 2014). Human activies can affect the water oil, acid, and detergents to flow into the water supply after .our daily activies are seen as harmless , however when I look at ait we as a society are all involoved in these activies these are common habbits cooking or maintenance on a car withcontaminants such as cooking oil, motor oils, detergents when washing dishes, household cleaning products, detergents for washing clothes, shampoos, toothpaste and just about everything liquid that can be poured down the sink could contaminate the water supply
