Dahr Jamail’s “Ocean of Pollution” first appeared in the magazine Aljazeera on June 18, 2012. In this article Jamail reports with various marine biologists, oceanographers, and others who study the oceans about their research and experience with ocean pollution. This article aims to convince the readers that there is an ocean pollution controversy in this world that goes unnoticed; and, it really focuses on making people aware of this particular crisis by providing information and statistics. Personal anecdotes, global effects, and solutions provided in this article are used in a strong technique which skillfully creates a mediocre, convincing article.
The information provided in this article elaborates on the toxic waste that is constantly

In this world we have a phenomenon afflicting Earth’s oceans and they are called “dead zones”. These are formed through natural causes, climate change, along with human activities and industrial waste, this has intensified the situation. The most local and world’s second-largest, along with the most studied human-caused costal dead zone is the Gulf of Mexico. This dead zone has grown vastly over between 2008 and 2011 by growing as large as 17,348 sq km opposed to when it was first 9,774 sq km. This progression has created issues exposed by Dr Nancy Rabalais, a marine scientist and executive director of the Louisiana Universities Marine Conortium, she quotes “There’s been a collapse in certain fisheries in areas of Lousiana, and trawlers are having to go further offshore” because of the expanded dead zone. The rise in global effects goes beyond the Gulf of Mexico, the Atlantic croaker study called dead zones “one of the most dramatic global changes owing to human activities over the last half-century” and said it now layers just about 250,000 sq km throughout the world. In this world, there were 146 dead zones recorded in 2003, by 2009 it doubled more than to 407. This increase is concerning to the citizens and water life of the world because it eliminates resources for food and habitat. By stimulating a solution to dead zones this world could go

The ocean is a beautiful place with colorful coral reefs and abundant schools of fish. But humans are harming the ocean. From ghost nets to overfishing, marina life is threatened. The articles Too Many Fishermen and Monster Debris both show how human beings are having a negative impact on the ocean by using strong evidence and descriptive adjectives.
First the causes of the dead zone will be introduced. Large contributors of excessive nutrients will be discussed. There is not one source to blame the Chesapeake Bay dead zone is a large problem with many variables that effect each other. Next the pressure that is put on the bay and its organisms will be discussed. A picture of what you might find out in the dead zone will be painted. The reality of the rapidly declining organism populations will be understood. Third, the possible solutions will be explained. Since this is a multiple variable problem there are many potential solutions that may or may not work. Last the lack of action will be observed. There are many solutions that could bring the bay back to life but the cost and lack of effort fr...
The dead zone in the Gulf of Mexico is a human problem, like most other disasters. What this means is that once the place thrived and was ecologically balanced, but we tipped the balance slightly and wrecked havoc upon the environment. It has been noted to occur since the 1950’s and is ongoing. The reason that this dead zone occurs is because of a phenomenon known as eutrophication. Eutrophication is when there is an excessive amount of nutrients in a body of water and it causes an abundance of plants to grow. In this case the nearby farms had been using nitrogen in their fertilizers. The nitrogen got carried into the ocean through rain and other forms of water. Nitrogen is an important aspect for plants to grow and a lack of it is normally what contains plants from growing in an excessive amount. Because farmers mainly use this, the dead zone has a considerable decrease in size in the winter season while it increases in size during the warm seasons. Eutrophication generally leads to another phenomenon know as hypoxia, which is the state of water when it is lacking oxygen. Having too much nitrogen leads to hypoxia, because there is a bloom in algae. Bacteria in the water then eat the algae and use all the oxygen in the process. Without oxygen in the water, a dead zone is formed, an area with little to no life. The dead zone in the Gulf of Mexico is around 6,000-7,000 square miles in size, but varies throughout seasons (source23879482371) (see Fig. 1).
Overall, the Gulf of Mexico dead zone is an area that should be taken very seriously. This is a part of the ocean that is drastically and undeniably affected directly by human activities. The economies surrounding the Gulf are very dependent on the resources they receive from it and would be devastated if economically-important species began dying off due to lack of oxygen. Although the dead zone varies in size from year to year, the area has increase exponentially ever since the birth of intensive farming practices involving nutrient-rich fertilizers. Thankfully, many efforts have been put forth to monitor and manage the dead zone. Revised farming practices along with greater environmental education for the general population with hopefully lead to a reduced risk of hypoxic conditions causing excess economic or ecological damage.
Ocean Pollution is a serious issue in today's global politics. The delicate balance of Earth's ecosystem is put in jeopardy when the ocean is not clean. Problem evolving from ocean pollution directly harm marine life and indirectly affect human health and the Earth's many valuable resources. Ocean Pollution is a Broad term that encpompasses any and all foregin matter that directly or indirectly makes its way into the ocean. This includes everything from the extreme: oil spills, Toxic Waste dumping and industrial dumping-- to the small scael: human activities and basic carelessness. Because the oceans and all other water bodies are invariably, somehow connected, and because they account for 3/4 of the Earth's surface, they are an ideal method of transportation for pollution, allowing the rapid spread of seemingly far away toxins into a river near you! It is increasingly important that we educate ourselves as to what, exactly, ocean pollution is, so that we can identify the causes at their source and take action in small and large ways, and hopefully, prevent this terrible form of pollution from getting any worse than it is today.
Source 4: A few reasons why beach pollution is happening is because Trash and other materials that beaches rivers, bays, estuaries and oceans eventually wash up on our beaches. It includes plastic bags, bottles and cans, cigarette filters, bottle caps, and lids.Any trash that is not thrown away and is just thrown in the beach and is in the sand can eventually go into the beach and make the water dirty.A lot of people just throw the trash in the water because they do not care.Some people are too lazy to go throw it away in the trash can.

The ocean is an abundant source of life. It is home to thousand of different creatures, provides a great source of food, and provides the earth with about one half of the oxygen needed to sustain life. (National Geographic) Pollution especially plastic, is a catastrophic problem. Ironically plastic, which is a material designed to last forever is generally used for things we tend to throw away. Every year about one hundred to two hundred billion pounds of plastic are manufactured. Only 31% of that plastic is actually recycled. Biomass packaging estimates 10% of that plastic ends up in the ocean annually. About 20% of it coming from ships and other platforms, and the other 80% coming from land derived sources, such as international garbage dumping, winds or tides either way it finds its way to the ocean.(Biomass Packaging Co., et al)
Due to the potential dangers of dead zones to the environment and economy in the Gulf of Mexico, the American government needs to make dramatic and controversial efforts to stop the growth of this dead zone.
...e effect of what humankind does to the ocean, the implications became far worse than any had individually realized. It is a very serious situation demanding unequivocal action at every level. We are looking at consequences for humankind that will impact in our lifetime, and worse, our children's and generations beyond that
Ecological shifts are threatening billions of coastal residents around the world. Planet Earth is shifting severally. Temperatures are rising, glaciers are melting, hurricanes are growing stronger, and oceans are expanding and covering coasts at disturbing rates. Many people question the reason of sea rise levels. But it is not a myth, scientist have proven that the icebergs 1that sit on Greenland and Antarctica land are melting at a rapid rate. But unfortunately, that is not the biggest contributor to this problem. Most of the sea rise levels are a cause of the rising temperatures of the water in the top surface of the oceans. Water expands when it is frozen, but it also expands when heats up.
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.

Did you know that more than 90 percent of all organisms that have ever lived on Earth are extinct? According to Pandey, the author of Humans Pushing Marine Life toward ‘Major Extinction’, nearly 10,000 species go extinct each year, and this rate is estimated to be 1,000 times higher than the natural extinction rate (1). Human beings are causing irreversible damage to the oceans and their wildlife, which is being led by two major reasons: Commercial fishing or over-fishing, which damaged the marine environment and caused a loss in the marine life diversity, and pollution, which is a primary way of the extinction causes that drastically modifies the marine life habitat. As a result of the commercial fishing and pollution, many of the marine species will start disappearing of the oceans. Briggs emphasizes that over-fishing “has induced population collapses in many species. So instead of having less than a hundred species at risk, as was the case some 30-40 years ago, there are now a thousand or more (10).”
