Recommended: Effects of ocean pollution on marine ecosystems
You never would’ve thought that marine pollution would affect you right? Wrong. The pollution underwater impacts everyone and everything on Earth. When different substances, such as plastic, foam, cardboard, aluminum, styrofoam, and newspaper, get thrown into the oceans, it can take up to 400 years for all of those items to degrade. Marine pollution is caused by humans, which affects everyone and everything on Earth.
Marine pollution is the human 's fault. Most of the pollution are man-made. Excess substances from companies usually end up in the ocean, contributing to the pollution. One of the largest reason for why marine life is beginning to decrease and become endangered is because of radioactive wastes being dumped in the ocean (Rinkesh).

Sea plants and marine animals are a necessary part of our ecosystem. They are a food source for humans and many other species. They help humans in many ways that people would have never thought of. As said by the National Oceanic and Atmospheric Administration, “Pollution can also make corals more susceptible to disease, impede coral growth and reproduction, and cause changes in food structures on the reef.” Corals are a food source and are a home to many marine animals. And when pollution changes the coral, it can have a tremendous impact on every marine animal. Deaths of marine animals are high, “Over one million seabirds are killed by ocean pollution each year. Three hundred thousand dolphins and porpoises die each year as a result of becoming entangled in discarded fishing nets, among other items. One hundred thousand sea mammals are killed in the ocean by pollution each year” (Rinkesh). This shows that a lot of sea animals are dying due to the polluted water every year. The oil that is “... spilled in the ocean could get on to the gills and feathers of marine animals, which makes it difficult for them to move or fly properly or feed their children. The long-term effect on marine life can include cancer, failure in the reproductive system, behavioral changes, and even death” (Rinkesh). This shows that oil causes many problems for animals and causes them to have poor health. The toxic substances that are let into the ocean kill a lot of animals every year and that should
For example, when the labors take oil from the ocean or sea, the oil may leak from the pipes and it will mingle with water. That time the living things in the sea are destroyed by the polluted water. So many fishes and sea organism may
This problem may seem prevalent and it is very important to know about. It affects marine life in many ways, but humans are also greatly affected.by this problem. People don’t realize what this problem does to them. However the human race can always work and solve this issue. People shouldn’t dump trash in the ocean or any water source. Trash can destroy coral reefs and other important ecosystems and ruin marine life. Most important sewage plants shouldn’t dump raw sewage into the ocean because it provides nutrients to harmful algae. Governments around the world should put more restrictions on sewage and the disposal of it. But if the solution wants to be solved people must work together.
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.
Fifty-million plastic bags enter the Australian waters every year, causing the death of thousands of sea creatures. Imagine you went on a trip to the Great Barrier Reef. As you arrive, it is clear to see garbage floating on the ocean and you can only imagine what rubbish lies beneath the surface. This disturbs me! What are we doing to our beautiful, yet innocent marine life?
Ocean pollution is bad it kills our coral reefs along with plants and animals. There is no stopping pollution at all it’s like a wild disease. We can try to reduce ocean pollution but it will always be killing the oceans plants and animals.
There are many causes to petroleum in b the oceanic environment. Oil naturally seeps into the ocean but the natural concentrations have been greatly exceeded. Shipping oil from one place to another contributes the most to oil in the ocean. The crude oil from transportation b is discarded into the ocean while cleaning bilges, which are the lowest compartment in ships, and transferring oil from tank to tank at sea. “Disasters like shipwrecks, oil tanker accidents, and offshore oil rigs fires continue to this problem, as does the disposal of urban garbage into oceans, dumping of waste oil by passing ships, commercial coastal and off-shore entertainment, and deep-sea industrial and nuclear waste dumps”(“Marine Water Quality”). Another large polluter is the oil industry. Tanker ports and refineries are located by the coast for shipping purposes. The coastal areas receive considerable damage from the spills. “Large numbers of seabirds are killed annually, their oil-matted plumage making flight impossible and exposing them to hypothermia. Oil-soaked fur of marine mammals loses its water repellency, also leading to death by hypothermia. Ingestion of oil by fishes, birds, and mammals may also result in death”(“Marine Pollution”). Another source of petroleum pollution is from the city streets. Oil runoff from urban streets and sewers enter waterways and the ocean. Oil has a very long term ecological impact on the ocean and the marine ecosystems. “The presence of oil in marine waters severely degrades water quality by clogging an animal’s feeding - structure, killing larvae, and blocking available sunlight for photosynthesis”(“Marine Water Quality”). Petroleum pollution has been a large problem for a very long period of time. “As early as 197p, oceanographic ecologists noted that they could rarely pull a net through the surface of the ocean without collecting some form of tar or
Water pollution has had devastating effects on the environment, which include irreversible effects on the oceans ecosystem. People often underestimate the importance of the ocean. They don’t realize how much damage pollution has caused to the ocean and the thousands of creatures that inhabit it. Earth is a huge place, but resources are actually very limited and will not last forever unless there is a balance. We must protect the resources we have in order for them to last into the next generation.
The article indicates that the influences of oceans pollution that made by humans and caused by a phenomenon called “dead zones”. First of all, there is a great amount of plastic in the ocean which causes massive consequences for animals of the entire marine food web. On the other hand, “Dead zone” also affect Earth’s oceans. “Dead zones” can formed by many causes, such as natural causes, climate change, along human activities and industrial waste. These is a national problem and humans need to have some regulatory mechanisms. Therefore, it can helps the “dead zones” reduced. The author mentions that the US Environmental

Pollution has a big effect on are oceans. There's so many causes and it all leads up to one effect which is pollution. The ocean covers up ninety-seven percent of are world's water supply. Seventy percent of the oxygen we breathe is produced by some marine plants. So clearly ocean and its water is are main thing that keeps us alive. Pollution is unhealthy and horrible because there's a lot of plastic in the oceans, land based pollutants, and the careless human interventions.

Oil spills and pollution can be the cause of death too much of the local marine life. An oil slick can cover up to 50 square miles polluting, and damaging all the ecosystems in which the marine life thrives killing thousands. All over the ocean surface and all over the land near the spill will be contaminated with crude oil ruin the lives of many of the animals near or who feed of the animals who were less fortunate not to make it out of the spill un effected.
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.
Global warming is one of the major reasons in marine pollution. For an instance in the year 2010 there was an oil leakage near Mumbai in the Arabian Sea.
Research from the University of California San Diego Scripps Institution of Oceanography said that species in the ocean consume a projected 12,000 to 24,000 tons of plastic every year in the Pacific Ocean (Nall, 2014). Pollution of recyclable materials in the oceans is one of the leading causes of why some marine species are nearing extinction. Many authors of articles and books analyzing this topic tend to agree that pollution of our oceans is a problem. The future of this problem is where their ideas tend to differ. The following four literature reviews attempt to demonstrate and support my belief that pollution is getting worse in the ocean and more marine life ecosystems are being affected, but there are things that we as humans can do to change this. Imagine a world where we didn’t have to constantly worry about the vicious cycle of humans affecting animals and then animals in turn affecting us through consumption.
