...Conventions to mitigate marine pollution Oil pollution: Oil tankers transport some 2,400 million tonnes of crude oil and oil products around the world by sea. Most of the time, oil is transported quietly and safely. Measures introduced by IMO have helped ensure that the majority of oil tankers are safely built and operated and are constructed to reduce the amount of oil spilled in the event of an accident. Operational pollution, such as from routine tank cleaning operations, has also been cut. The most important regulations for preventing pollution by oil from ships are contained in Annex I of the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto (MARPOL), The International Convention for the Safety of Life at Sea (SOLAS), 1974 also includes special requirements for tankers. Chemical pollution: * Chemicals carried in bulk Carriage of chemicals in bulk is covered by regulations in SOLAS Chapter VII - Carriage of dangerous goods and MARPOL Annex II - Regulations for the Control of Pollution by Noxious Liquid Substances in Bulk. Both Conventions set out the international standards for the safe carriage, in bulk by sea, of dangerous chemicals and noxious liquid substances. The Code prescribes the design and a construction standard of ships involved in the transport of bulk liquid chemicals and identifies the equipment to be carried to minimize the risks to the ship, its crew and to the environment...

...temperature, volume of the spill, waves, speed etc. Techniques like low tech approaches which involves containment and skimming and burning: and high tech such as varying of sophisticated dispersants e.g. giant separators have been remedies used for oil spill cleanup. Oil spill have destroyed a number of marine and terrestrial wildlife species. A terrestrial animal that depends on seafood dies of hunger due to the destruction of marine food by oil spill. Some marine animal that live and breathe in water dies off because of the contamination of water. The first step to approach when handling oil spill cleanup is quick action. Once we find out there is a spill, speed and accuracy is important for cleanup process. Locating the source of oil spill, its size and thickness etc should follow. According to Larry Nies speed and accuracy can be achieved by using a method known as visual observation from the air, with still and photographing. This method is the cheapest but not the best, it has limitations like inability to see well due to atmospheric and sea conditions etc. A better method but expensive one is the use of airborne sensors. There are some short comes involved in detecting marine environment oil spill like the thickness of sensors etc. Ways involved in recovery of oil spilled. (Physical recovery) Containment and cleanup measures: Minimizing the oil spill spread in water bodies when oil is spilled is important. These will safe extra resources which could be out into clean other...

...therefore plastic bags should be banned on a national level. Although there are some positives to using plastic bags, the negatives of using the bags out way the positives. Landfills are becoming filled with plastic bags waste, according to the Clean Air Council, “30,000 tons of waste is created from plastic bags each year”. Not only does plastic bags accumulate trash in landfills, they are seen more and more in the ocean and other water sources. “Plastic constitutes approximately 90% of all trash floating on the ocean’s surface, with 46,000 pieces of plastic per square mile”. All this plastic is affecting the ecosystems of the wildlife and the basic natural cycles of various animals. According to the online Website Ocean Crusaders, “100,000 marine creatures a year die from plastic entanglement”. This includes sea turtles mistaking plastic bags for jellyfish and trying to eat them. Along with the waste produced by the bags affecting the wildlife, these bags use 12 million barrels of oil needed for 100 billion bags. The positives out of using...

...ENVIRONMENTAL POLLUTION – OUR CONCERN Environmental pollution is a cause for concern, not only for us but also for mankind as a whole. The last century has seen the rise of this menace assume gigantic proportions, so much so that it has cast its gloomy shadow on nature itself. The diminishing ozone ionosphere leading to global warming and the unpredictable seasonal variation, are some of the adverse effects of pollution that are threatening the environment in which we live. Pollution is a by-product of the unprecedented industrial revolution that we have seen in the last few decades. The establishment of large scale factories belching out smoke, fumes and chemically hazardous waste, has now started having a telling effect on the environment. This couples with the unprecedented growth of automobiles and the ever-increasing human population are some of the factors that are making environmental pollution a cause for concern. The effects of pollution are all pervasive – affecting mother earth, animals, birds and man. An immediate fallout being the reduction in the oxygen content in the atmosphere, presence of potentially harmful gases causing diseases asthma and lung cancer which are sometimes fatal. The large-scale release of chemical wastes into the rivers and streams are the cause of dwindling aquatic life in the river and oceans. This also adversely affects the soil where the river water is used for irrigation purposes. Every now and then we see in the news...

...Plastic Does Not Belong in the Sea “For whatever we lose (like a you or a me), it’s always ourself we find in the sea” this is a beautiful phrase E. E. Cummings once said. The ocean is vital for the environment. It’s well known to be one of the most important natural resources of earth. At the same time, it’s very much affected with pollution and trash. The photograph “Polluted Sushis” shows three sushis placed in a white platter, they are wrapped around plastic in place of the usual seaweed. This image leads to an understanding that nothing goes by without a consequence. The message that is being sent by this image is powerful in the sense of saying that what we throw into the ocean, will eventually come back. The JWT advertisement agency in charge of the add “Polluted Sushis” does a great job using ethos, pathos, and logos to help effectively persuade the audience to stop littering the sea. The use of pro environmental ads nowadays is quite usual. Some of them are very harsh and direct, they go straight to the point and leave no space to wonder. Nevertheless, there are some ads which are more subtle with their message. They suggest the problem in a more creative way giving the viewer the possibility to reflect upon their add. I find this mechanism much more effective than the first one because it gives a way to internalize the problem shown. Precisely, this is what happens with “Polluted Sushis”. It achieves that people are most likely to perceive the possibility of what is...

...opportunities. It is prone to severe natural disasters such as cyclones, storm surges, floods, erosion, soil salinity etc. In combination with other natural hazards various forms of man made pollution made the coastal dwellers very vulnerable and ultimately slowed down their socio-economic development. This study will seek to analyze the vulnerabilities and risk of coastal water and suggest adopting appropriate measures for mitigation and management of coastal environmental pollution to the extent of generating environmental awareness among people. The coastal region gets polluted as the pollutants are carried through different rivers and canals to the sea. Water channels are used for dumping industrial wastes that ultimately end up in the sea. There is no facility for waste treatment in densely populated urban areas. As a result, water pollution is increasing. About three thousand ships including oil tankers come to our ports every year. There are several thousand mechanized trawlers and boats that spill oil. Sea is also polluted by oil spill because of accidents in ships. The authority fails to check pollution as they have no receiving or collecting vessels to face the emergency situation during oil spillage. Even our Port Authority has no laboratory to measure the extent of the pollution. Foreign and local ships find the Chittagong Port and its outer anchorage a safe dumping area for their waste, taking advantage of poor laws and their lax implementation due to logistic support...

... May 22, 2016 was earth day around the world and was celebrated in ways of cleansing the earth. On this windy cool afternoon in Brooklyn, NY, the Gowanus Canal got a visit from the staff and students from St. Francis college. They were also trailed by a few local residents, this group of earth day goers went about the pollution within the country dirtiest waterway. They all gathered around on the bridge above the canal and said individual prayers. They said that everyone complain about the canal but no one is cleaning. So they saw no harm in asking god to bless the polluted canal. 2. What else is known about the topic? What other research is out there. Issues have two sides, present both of them. Something else that is fascinating about this topic is that there was a $500 million project set up by the city to clean up the canal but the project is moving slower than a snail on the run. The canal also empties into the New York Harbor. 3. What are the essential facts? The essential facts about this topic is that the politicians that promise so much before they enter office is not doing about this canal that is in the middle if there city and is pollution you can see with your eyes. Another fact is that this group of earth day believers had enough faith in their prayers sent to god. 4. What are the major ethical issues and concerns? (as it applies to the general public, to taxpayers, to the government or to the nonhuman organisms living in the...

...Do you think ocean pollution is an issue? Well, over two thirds of Earth's surface is covered by water and all of it has been affected by some sort of pollution. Ocean pollution causes many chemicals and foreign substances to get into our air, water, and food, killing the wildlife and affecting the cleanliness of our waters; it is extremely important for us to all come together in order to stop ocean pollution. "The single biggest problem in reaching international agreement on a topic lies in convincing sovereign nations with different goals, opposing political systems, and fluctuating positions in day-to-day politic that their interests all lie in the same direction" (Cousteau 106). Pollution gets into the ocean from many sources but has...

...The article is called “Oceans of pollution” (Al Jazeera, 18 June 2012), Dahr Jamail. He shows the plastic pollution in the oceans on the Earth’s crisis. If the issue is not addressed, it will be unpredictable long-term consequences, with a mass extinction of ocean species. His rhetorical goals of explaining are quotations from scientific experts, cause-and-effect reasoning, and powerful visual imagery. The stimulus for the article was a series of scientific studies that demonstrate the dramatic worsening of ocean pollution in recent years. According to author, massive gyres of plastic garbage are developing in oceans that are harm to fish, turtles and other creatures. “Dead Zones” – where are algae blooms which runoff of nitrogen and phosphorus...

...environmental issues and concerns such as pollution, ozone layer thinning, global warming etc. Human impact is a serious threat to ecosystem and food chain of Antarctica. In the last few decades, various marine species of Antarctic ecosystem have been brought close to extinction because of human activities in various forms such as pollution from sewage and other contaminants, overfishing and other mixed activities and interference like global climate change caused by human emission of carbon dioxide and other greenhouse gases, ozone layer depletion, global warming etc. This all leads to damage of food web and ecosystem of the Antarctica. Another serious impact of emission of carbon dioxide is ocean acidification, which is serious damage to the marine ecosystem of Antarctica. These activities are the main causes of disturbed environment of marine ecosystem of Antarctica. Another factor contributing to Antarctica's ecosystem disturbance is the commercial aspect of human activities. Human are harvesting krill to feed their animals and fishes which is negatively affecting the ecosystem of Antarctica. It is affecting the volume of krill and other fishes which are important source of food chain of Antarctica. Because of less krill, food chain of Antarctica is getting disturbed. Researches have shown that due to global warming, sea temperate is rising and cause less formation of ice packs during the winters. It is affecting the marine creatures and causing few species to extinct...

...Describe how the animal species richness found in the Galeolaria caespitose clump biotype could be affected by pollution Marine ecosystems are known to have rich biodiversity of species and therefore generally thought of as being stable and resilient to natural progressions of the earth (Johnson, Roberts, 2009) Disturbances in the habitat by unnatural means, such as pollution, can harm the balance of these ecosystems as the species are unable to adapt to the unusual contaminants that would not naturally encounter. One part of this ecosystem is the calcareous tubes secreted by the polychaete worm called Galeolaria caespitoa which are found in large clumps on pier pilings and in the intertidal zones of rocky shores (Ladiges et al. 2010). When viewing the calcareous tubes for the first time it appears that there is only one species, the Galeolaria caesplitoa, present but upon further inspection a diverse range of species can be found including annelids, molluscs and arthropods. These species all exist in this clump and benefit from the stability and protection that the clumps provide, but the introduction of a unnatural occurrence such as pollution can affect the way these animal feed, breed and breathe. The main source of pollution that comes into contact with marine ecosystems is sewerage which contains waste materials from everyday human activities such as slaughterhouse wastes, animal remains, domestic wastes, industrial wastes, faecal matter and many others (Islam, Tanaka...

...Ocean Pollutants Found in Tuna Weaken the Immune System There is actually an island of garbage twice the size of Texas in the Pacific Ocean. Has anyone ever wondered where all that trash came from? Where all that trash ends up? Or who gets affected by it? A solution should be made for ocean pollution for the sake of ocean life, but specifically, Yellowfin tuna. Ocean pollution is caused by many reasons, oil spills. Fertilizers, garbage, sewage disposal, and toxic chemicals. Ocean pollutants found in Tuna are weakening our immune system, is affecting the entire food chain, and is also harming sea life. With this in mind, ocean pollution is being detrimental to not only Tuna, but also the ocean and humans as well. As an illustration, ocean pollutants were found in Yellowfin tuna and is making our immune system weaker. Meaning, “Persistent Organic Pollutants, or POP, affected an important cellular protein found in most animals and plants.” (Ocean Pollutants Found in Tuna Weaken the Immune System, TakePart) TakePart also explains that, “The protein, called P-gp, usually ejects toxins from the body. But the team found that all 10 pollutants weakened P-gp’s protective function.” In other words, pollutants were found in yellowfin tuna which affects our protein cells and also weakens our immune system. Thus, ocean...
