“Carried by snow melt, rain water, and groundwater, NPS pollution contributes sediments, nutrients (nitrogen and phosphorus), toxic substances, and pathogens to water bodies” (Maine Rivers 2005, ijc 2008). The Non Point Pollution generally due to stormwater in the downstream portion of the river; which are the most populated areas situated near the estuary;With the stormwater large amounts of pollutants are washed off to the river because of the impenetrable surfaces of that area which does not allow water to seep into the ground. Other sources of Nonpoint pollution are seepage from broken sewage and septic tanks, runoff from construction sites ,nutrients,sediments and chemicals from agricultural farms and roads. According to the report of International Joint Commission in 2008; “This untreated runoff may contain litter, dust, soil, oil and grease from roads, garden waste, chemicals, and nutrients and pathogens from animal feces and fertilizers” (IJC
Sarah Freeman’s article in The Ethicalist explains the negative effects humans have on the ocean. These negative effects include plastic pollution, global warming, and worst of all, overfishing. Overfishing occurs when a fish species is wild caught faster than it can reproduce. This leads to fewer fish in the ocean, meaning less marine biodiversity (Freeman). After Freeman spends most of her article explaining how the oceans are suffering, she then starts talking about what can be done to prevent a baren sea.
WITH only the clothes on her back and a toothbrush in her pocket, Mariney, a Mexican-American NGO worker, flew from Beirut to Cyprus in April. It was a routine visa run made by many expatriates in Lebanon before the expiry of their two-month “tourist" visas, which are free on arrival. But when Mariney was clearing customs, security officials told her she would not be allowed to return to Lebanon. Two months earlier Mariney’s employer, a Chicago-based human rights organisation, had started the paperwork to get Mariney a work visa.
I’ve had a couple of life experiences that have shaped my mind to think differently, such as when I nearly drowned in the ocean, or when I fractured my ankle by jumping over a bean bag chair. With multiple weeks spent in a boot and a slight but undeniable fear of rip currents, I’ve managed to gather an interest in orthopedics and ocean life; as a result, I have decided to research further into being a surgeon (specializing in orthopedics), and a marine biologist. These two careers contrast drastically, specifically in required education and salary, work environment, and job outlooks. Although being an orthopedic surgeon and a marine biologist both require a certain amount of extended education beyond high school, they contrast in how much is necessary. According to Barbara Sheen, “postsecondary aspiring surgeons must obtain a bachelor’s degree, which usually takes four years.
It is well known that the human population has been polluting the land and oceans for years. Usually pollution is thought of as physical pieces of garbage, harmful chemical agents, or biological pollutants. However, another form of pollution that spreads across our oceans includes noise pollution from a variety of natural and man-made sources. Natural acoustic pollution can originate from sources such as earthquakes, lightning strikes, volcanic eruptions, and noise from other organisms in the water (Weilgart 2007). Wilson et al.
Nowadays debris is an integral part of humanity life. Mankind thinks about how to make the product easier and cheaper to use, but nobody cares what happens with waste after it was used. We contaminate the environment with every decade increasingly: muddied air and water, global warming are an output of human life. The worst thing is that from such attitude other living beings are dying. Millions of animals and birds cannot withstand such environmental changes; their populations become smaller and, eventually, disappear altogether from the face of the earth.
Marine animals are dying because we as humans can’t keep our waste in the right places. Pollution negatively affects marine animals because garbage is making it’s way into the oceans, taking away their homes, and killing them. How can we be more careful with our garbage? How is garbage taking the animals homes away? How is garbage killing marine animals, and what will happen if they go
In an academic journal titled Marine pollution control: law, science and politics written by Douglas M. Johnston, he claims, “any effective combination of adjustments and precautions involves difficult organizational tasks that require unprecedented exercises of political will and novel feats of legal imagination” (Johnston, 1972, page 69). Years worth of neglect and irresponsibility mean that the damage has already been done. As with any irreversible problem, the only thing left to do is try to take preventative measures. Be mindful that waterways carry litter, and oftentimes an ocean is the finishing
"Deep-Sea Biodiversity and the Impacts of Ocean Dumping. " NOAA's Undersea Research Program, 5 Apr. 2005, I plan to use this research article published by the Undersea research program to support my argument that dumping waste into the ocean is have adverse effects on the ocean's ecosystem on a global scale. This source is a government funded web page, which I believe will give my argument additional credibility.
Marine organisms are animals, plants, and other living things that live in the ocean. A Marine biologist is a scientist who studies marine organisms and studies the bodies, behavior, and the history of marine organisms. They also study how marine organisms interact with each other and their environment. I have chosen to research about Marine biology because I would like to learn about sea life, the ocean, and its surrounding environment. To start off, a Marine biologist might study coral, crabs, fish, microscopic marine organisms, sea stars, seaweed, squid, or whales.
Before, it was assumed that because the ocean was so big, vast, and deep, that the effects of dumping trash and littering into the sea will only have minimal consequences. But after decades of littering, we have seen the consequences. Oil spills, floating plastic, and toxic wastes
Plastic pollution in the ocean Introduction Rachel L. Carson said in her book “Water, soil, and the earth´s green mantle of plants make up the world that supports the animal life of the earth” (63). In other words, our planet was always a place which was dominated by nature and it had essential relations between plants and other plants and between plants and other animals (Carson, 1962). Since the modern human started to conquer the world a lot of things have changed and technology has taken over. My essay is about a quite new but very big problem which affects our wonderful planet; it is about plastic in the ocean.
Marine pollution such as presence of organic matter in the ocean can result in the condition known as hypoxia or oxygen depletion and this can have adverse effect on the marine life including plant and animals and fish. Death of these fish can result in loss of millions of US dollars that are generate from the fishing industry. Marine pollution can also result in presence of foul smell resulting from the decomposing sewage being directed to the ocean and this has the effects to hinder recreational activities taking place in the sea as well as cause discomfort and breathing problem to the surrounding population (Laura, 11).marine pollution can also result in danger to human health. The human swimmers and water sport lovers can become endangered by swimming in the polluted marine waters (Laura,
Pollution is the introduction or release of substances or energy that decrease the quality of the marine environment. Many pollutants are toxic of harmful to marine life (Castro and Huber, 2010). South Africa is known around the world for being one of the most diverse marine environment in the world, with 83% of the known fish families residing in South Africa (Van der Elst, 2007). There are also many marine species that are endemic to South Africa, which means they are only found in South Africa. Almost 30% of the South African population lives on the coastline (Taljaard et al. 2006), which has led to the urbanization of the coastlines and which then led to the industrialization of these areas.
“ Natural gas industry has been identified as a major source of water pollution “ ( source 1 ). This quote from source 1 explains how out of all the ways of polluting the oceans, oil is always one of the worst. “ 8 million metric tons of plastic trash enters the sea from land every year “ ( source 4 ). This quote from source number 4 explains how every year tons and tons of plastic from land, gets into the oceans and continues to pollute. Garbage is polluting the oceans so much that the water is getting so bad, people are getting ill from drinking
