The Effects Of Water Pollution In The Ocean

Better Essays
Too much pollution in the ocean can make the seawater become too acidic. When the water is too acidic, some marine animals cannot survive. For some marine animals, acidic water reduces their ability to grow shells. “For instance, the thin shell of marine snails is easily eaten away by acid waters” (Levete, 15). The ability to not grow shells can decrease its chance of survival. The marine snails will have less protection without those shells, so they could get eaten more easily by predators.
The number of dead zones and endangered animals are rising due to contaminated water. “Hypoxic zones are areas in the ocean of such low oxygen concentration that animal life suffocates and dies, and as a result are sometimes called ‘dead zones.’ One of

According to the article “Jet Set; Climate Change”, “the upper layers of parts of the Arctic Ocean are hotter than they have been for at least 2,000 years” (68). There is less oxygen as the water gets warmer. As a result, the animals that live at the top of the ocean zone will have to swim deeper to keep cool. This will disrupt habitats and also the food chain. An example of a food chain affected is phytoplankton. These tiny organisms cannot survive with temperature change. If there is a decreased amount of phytoplankton, the food chain is in trouble since many animals depend on this food source. This will cause a domino effect. For example, phytoplankton are eaten by zooplankton. The zooplankton are then eaten by fishes. The squids eat the fishes. Squids are finally eaten by the sperm whales (Stanley, 94). If the supply of phytoplankton are low, these organisms and many others will also be affected. According to the book, Destroying the Oceans, “The world’s phytoplankton produce at least half of the oxygen we breathe” (16). The endangerment of phytoplankton will not only affect marine life, but it also will affect human life. In other words, a low population of phytoplankton will also result in a low level of oxygen for

    Their luxuries will significantly decrease due to a copious amount of carbon dioxide emissions from climate change. Starting with the seafood that they eat at this current rate of acidification will dissolve the shells of living organisms within decades (Foy. 1) that contribute to key organisms in the marine ecosystem to most popular seafood that they eat like crab and shrimp. Species that make shells out of calcium carbonate are particularly compromised in acidic waters, where the carbonate ions needed for shell-making are not available. (Leader.…

    Although zooplankton are a small part of the ocean, they end up feeding most aquatic mammals bigger than them. A variety of experiments show that higher levels of acidity result in dissolving zooplankton 's shells. This could lead to zooplankton living in tropical areas to become extinct by the end of the century, which would result in a food shortage for many of the ocean 's largest creatures. In the Southern Ocean, the shells of pteropods are already dissolving, due to the rising acidity of the water in the Southern Ocean. If ocean acidification continues to occur, marine organisms will continue to experience harm due to the rise in acidity of the ocean and risk…

    [2] Salt also negatively impacts other animals’ populations. The chemical chloride from salt causes the rates of survival for amphibians, crustaceans, some reptiles, fish, and other organisms to decrease. [3] Overall, salt is essential for life, but can be fatal if not used in moderation.…

    Whilst sea turtles are being caught in nets, and in fishing gear. They also eat plastic bags thinking that they are jellyfish. Life in the oceans is decreasing, the reasons are numerous and the effects are disastrous to the environment, thus measures are to be taken to insure no further deterioration happens especially to the creature inhabiting…

    While the hatchery does raise thousands of young fish, many of them don’t survive long enough to reproduce and the complex steps that go into their reproduction is disrupted by faulty human practices. Firstly, fish like salmon are artificially fertilized and fed food treated with antibiotics and chemicals that negatively affect the fish. Since the fish are kept in small, confined spaces, the fish become less intelligent because they live in a simplified environment. Because there is a lack of diversity in their environment, there is a negative psychological effect on the fish that makes them less likely to survive in the completely different environment of the wild. Also, since they do not live in streams, fish like salmon are unable to live with a specific scent that will guide them back home to reproduce.…

    Other creatures who depend on these plants will lose their source of food and they will suffer as well. Moreover, acid fog has a negative effect on trees. Because of less nutrients, the trees aren't abele to absporb the sunlight. Acid rain also affects aquatic animals because it changes their pH level. By decreasing pH level, the aluminium level increases and causes toxic water for fish.…

    A study found that the squid are vulnerable to the acidic conditions, and may face greater challenges to survival if this condition continues to amplify (Lacoue-Labarthe). The question is that how ocean acidification affects on the squid population. However, the answer might not be easy since there is a limited number of studies that have investigated squid response to the level of pH in ocean. There are many studies have shown that the most effect species are calcifying organisms at the bottom of the food chain are prey for marine organisms in higher trophic levels. Reducing the pH level in ocean also decrease the availability of dissolved carbonate ion necessary for shell formation.…

    Elizabeth Halliday tells us in her article that it is not true that overfishing is the only cause of the decrease in the fish population. She says that some other causes in the decrease in the fish population is ocean pollution and litter in the ocean. Some fish die or get very ill for many reasons. One example, is if there’s an oil spill then fish in the area would most likely die. The pollution might make the fish very ill or kill them.…

    New research suggests that a disease now killing many sea turtles -fibropapillomas-may be linked to pollution in the oceans and in near shore waters. When pollution enters the water, it contaminates and kills aquatic plant and animal life that is often food for sea turtles. Oil spills, urban runoff from chemicals, fertilizers and petroleum all contribute to water pollution. Because the ocean is so large, many incorrectly assume that pollutants will be diluted and dispersed to safe levels, but in reality the toxins released from these pollutants become more concentrated as they break down in size. As a result, these smaller, more toxic particles become food for many links in the food chain, including sea…

    The effects of freshwater acidification as carbon source changes from carbonate (HCO3) to carbon dioxide (CO2), release of toxic metals, and freshwater fauna and flora gradually changes. Some species of fish or animal can tolerate reasonably acidic water, the animal or plants that eats it might not. Furthermore freshwater acidification can lead to decline and loss of fish population. A pH of 4.5 no fish is to survive. A decrease of pH is most correlated with an increase of toxic metal availability.…
