Toxins from horticulture have influenced the marine 's biological community in ways that may not be reversible, and may likewise be gradually hurting waterways, streams, and waterfront waters. Pesticides and compost are two noteworthy segments that have irritated the marine 's environment; both contain unsafe chemicals that can be perilous to living life forms in the water. Compost and pesticide keep running off from substantial ranches may have started blasts of marine green growth which may disturb the sea 's biological community by creating monstrous sprouts in marine waters (Schwartz, 2005). Winds cause nitrogen and different supplements from the ocean bottom to surface, which advance the development of green growth called phytoplankton. Phytoplankton is a primary wellspring of nourishment for some living creatures in the marine waters. Farming toxins may have activated phytoplankton to deliver unsafe blossoms in tides, which are radiating noxious poisons to marine life. These noxious poisons are hazardous in light of the fact that the oxygen levels are step by step decreasing in waters, which may have fatal results for marine life (Schwartz, 2005).…
Are there high concentrations of fecal coliform in the St. Lucie River that make it dangerous for humans and animals that are in contact with the water?…
Enteric bacteria are members of the Enterobacteriaceae family of microorganisms. These gram negative, rod shaped, facultative anaerobes are found in the intestinal tracts of humans and animals. Enteric bacteria can be pathogenic; however, they are also a normal part of human bacterial flora and are therefore found in both healthy and infected hosts. This is why fecal matter found in contaminated water and food supplies as well as public recreational areas such as beaches can cause serious intestinal tract infections and urinary tract infections, among other diseases (Todar 2012). Escherichia coli is a major…
Abstract Because water serves as vehicles in the transmission of many pathogens, coliforms are commonly used as indicators to monitor the quality of water. I hypothesized that Lake Thoreau would have more fecal coliforms because it is a more stagnant environment meaning more animals can stop their and release their feces, and also the animals that reside there continue to reproduce, leaving no exit for their excretions. By using the MPN test, I was able to detect the coliforms from the fermentation in lactose broths, then with the IMViC test I was able to identify the enteric bacteria colonizing in the water samples. By then end of the experiment, it was apparent that the USM Creek and Leaf River were the two that tested positive for possible…
The pollutants in our oceans and seas are not only hazardous to marine life but also to the wildlife and humans that consume them. Pollutants are threatening ecosystems not only in our country, but also in others (Sielen).…
I found this article to be very informative. I and I presume many others were not aware of the large amounts of disease causing pathogens on the beach. When I go to the beach, I always see people eating lots of food and playing in the sand, but I never see anyone using hand sanitizer or washing their hands before eating. I think that if more local studies were put out it would inform the public and they would be able to protect themselves from dangerous pathogens. In the article I saw a picture of and pipe that was releasing raw sewage directly into water at Delray Beach in Florida. How can people be dumping sewage into the water, where people eat and drink and expect no negative outcomes? I personally believe that this needs to be stopped…
Rainwater also carries contaminants like trash, car oil, and animal fecal waste from the streets and roads into the storm drains (“Stormwater Runoff”). All of these pollutants also eventually lead into the Bay. Many of the aquatic organisms may be intoxicated or trapped by the oil and trash. This will lead to the depletion of their populations and consequently affect the other organisms in their food chain, and the humans that rely on them as a source of food (“Stormwater Runoff”). The chemical contaminants affect the population of all sorts of aquatic life in the Chesapeake Bay. For example, the “small bottom dwelling organisms take in the contaminants through skin contact while feeding” (“Chemical Contaminants”). Larger fish then consume the chemically contaminated fish, and accumulate the toxins in their body tissue (“Chemical Contaminants”). Mammals and other wildlife then consume these contaminated fish as the chemicals keep harming the predators of contaminated prey in the food chain (“Chemical Contaminants”). Many Marylanders rely on aquatic organisms, like crab, that they fish from the Chesapeake Bay as a source of income. If the pollution of the Bay is not stopped, the disappearance and contamination of these organisms will bankrupt many entrepreneurs in the state. These aquatic organisms will not be able to survive from the continuous exponential growth of toxins in their ecosystem.…
Since the first inhabitants of Earth, the ocean has been a necessary resource for our way of life. However, since the first human inhabitants on Earth, we have poisoned this great resource. At first, it seemed harmless, what is one piece of trash going to harm in such a massive body of water? If everyone in the world who ever lived contributed just one piece themselves over their life time, it would add up to almost one-hundred and eight billion pieces of trash (Haub). Now ask again, what is one piece of trash times 108 billion going to harm in such a massive body of water?…
There are many contributing pollutants to bioaccumulation in oceans such as toxins, marine debris, oil, sewage, eroded soil, and heavy metals. In the past, dumping small amounts of pollutants into the oceans, known as dilution, was not thought of to be a threat to the environment because all of the oceans combined cover 75% of the earths surface. There used to be a saying which was common, “The solution to pollution is dilution.” Eventually it was found that dilution was really not the solution. Not only does bioaccumulation affect marine life, it also has a huge…
The author, Kwame Anthony Appiah, starts the essay, The Case of Contamination, by describing the veranda of a palace in Ghana. His description paints a vivid picture of a place full of custom, color and tradition. However, he presents a contrast by describing that some of the people were dressed in western suits, sporting cell phones and having business meetings. This place is a mixture of tradition and innovation subsisting in one place. The author presents the arguments of globalization of the standpoint of cosmopolitans, the preservationist and the neo-fundamentalist stating also how religion plays a role in each.…
The scientific realm of ocean trash and its impact has been left horrifyingly untouched and is only now being taken up. Consequentially, we have been oblivious to the negative affects of this issue to the point where (1) the largest landfill on Earth is situated in the Pacific Ocean, known as the Great Pacific Garbage Patch. Although we lack a proper understanding, it is still an enormous threat to our planet and to us as humans, a fact that we seem content to be ignorant of. Already, there are (2) well over five trillion known scraps of garbage amuck in the ocean. Another moment cannot be spared if we are to do something. The immense amount of ocean trash afloat has caused concerns for marine life, human health, and even economy. As long as…
Have you ever been to the beach? I have and swimming in the ocean is one of my favourite things to do when I go on vacation! You wouldn’t want someone to come into your house and throw their cigarette butts or their plastic drink container on your kitchen floor when they’re done would you? I know I wouldn’t. Littering in the ocean does not magically get rid of your garbage; the marine wildlife has to deal with it in their homes. Roughly 75% of our earth is covered with water (IDRC 2010). Many people think that when you dump trash into the ocean that nature will biodegrade. It can take up to hundreds of years for this trash to fully decompose. People need to take into mind that the tiniest piece of plastic can get trapped around animal’s necks, dumping garbage into the ocean can severely damage coral reefs which is home to many marine wildlife , and that red-tides can cause medical complications to animals and people.…
Chelsea Rochman is an ecologist at the University of California that has been trying to answer many unclear questions about ocean garbage and just how badly it’s affecting the ocean and marine life. Rochman believes that a lot of the supposed “threats” that scientists say ocean garbage pose had not been tested at all, and that the scientists had an insufficient amount of information to prove that the debris is doing or going to do exactly what they claim. Rochman and her colleagues studied over a hundred papers on the subject of ocean garbage and it’s effects. Eighty-Three percent of the perceived threats of ocean garbage were, in fact, proven true by scientists, while for most of the remaining 17%, the studies were simply too low-quality and…
One of the major factors that cause coral reefs to decay is pollution. In coastal areas new development and landscape can cause runoff. The runoff can include excess nutrients, sewage outflows, and other pesticides from agricultural areas. These pollutants can reduce the oxygen levels of the water which leads to a decline in coral growth and reproduction. The runoff can also cause different types of coral diseases. Another type of ocean pollution is marine debris. Marine debris is trash that is disposed of in the ocean. The trash consists of metals, plastic, glass, and other items that are dropped off of ships, washed…
John Dutton’s essay “Toxic Soup” (2006) speculates about the effects that humans have on pollution in the ocean, as well as ways the damage can be reduced. In this essay, Dutton incorporates his personal experiences as a surfer and nature lover with statistics and his knowledge of the effects of water pollution on animals and humans. Dutton’s purpose is to raise public awareness of the need for environmental protection of the ocean in order to preserve and improve nature’s status. Given the language and references used, Dutton is writing for college educated adults interested in science and the environment.…
