Recommended: Global warming a big issue in the world
The ocean is the largest water body that covers 70% of the Earth’s surface. In this giant pool, thousands of known and unknown species thrive and create massive food web and environment. For several centuries ocean had and still is providing us with seafood, salt, minerals, transportation, and even leisure. However, in return, humans had leaked toxic chemicals, dumped trash, over-captured fishes and sea organisms, and destroyed environment and geography. Also, due to humans’ ever growing carbon usage from burning fossil fuel had made Earth and ocean temperature unnaturally hot. Today, as the result, the ocean had become a rotten pot of seafood and toxin. Although regret is always too late, if people realize this danger as an imminent threat and change, it is possible to revive the ocean. Global Warming Global warming is one of the biggest environmental issues not just for the ocean, but also for the entire Earth. The global warming is caused by greenhouse gases such as the carbon dioxide and methane, which create an invisible cover around the Earth. The cover or the atmosphere with the green house gases lets in the sunlight but do not let the reflected light back into the outer space. This is known as the greenhouse effect. Ice Caps Are Melting The global warming had great impact on Artic ice. From 1979, more than 20% of Arctic ice has melted away due to increased surface air and ocean temperatures (Farmer 9). Also, the accumulated area loss is approximately a third of continental US. Although, melting of sea ice does not directly contribute to sea level rise because this ice is already floating on the ocean, it contributes to sea level rise in another indirect way. First, the ice’s albedo effect has a major role in reflect... ... middle of paper ... ... Ocean 102. 29 Apr. 2014. Reading. Ricciardi, Michael.

...: The data shows that if there is minimal or extreme acidification in water then oceanic life will be experiencing severe stress. The findings show that my hypothesis was proven correct. Due to this project being a mini projection of the entire ocean it is clear that if humans continue adding chemicals into the ocean then the acidification will rise putting unwanted stress to the fish.
Somehow our oceans maintain the balance between being some of the most powerful forces on the earth, and the most easily disturbed masses on the planet. There are so many things that could go wrong within the countless cycles, and the delicate processes that stabalize nature and sustain the biosphere; and people are continually interfering with these cycles. Ocean acidification is one of the most obvious results of human interference upon nature. “Pollution is nothing but the resources we are not harvesting. We allow them to disperse because we've been ignorant of their value.” ("R. Buckminster Fuller, in Memoriam").
Ocean acidity will spoil marine ecosystems if it remains persistent. Preserving sustainable fishing industries will become unmanageable if the carbon dioxide absorbed by the world’s oceans is not considerably abridged.

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.
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)
Our oceans take a large beating every day by the extremely large amount of pollution humans produce. Our society easily dumps their waste into the oceans to dispose of the excessive amount of garbage, sewage, and chemicals, but this small and simple solution is creating an even bigger problem. The way humans dispose of their wastes is causing the death of our beloved marine life. Not only are we killing off our animals, our food source, and our resources, we are also minimizing our usable water. By having a better understanding of the problem on the severe dumping, it will be easier to find ways to help minimize the pollution that is going into the ocean.
While a beautiful sunset on the beach can be astounding, a spectacular scene is not the only benefit oceans provide. Without the oceans, we would not have adequate amounts of oxygen to breathe or enough protein to eat. The Earth's climate would not be inhabitable for human beings and many animals. The oceans supply medicines, food and drinking water which arise from ocean processes. Out of the five oceans, the Pacific Ocean is the world’s largest and deepest ocean. It spreads over an area of 165.2 million square kilometers. More than 25,000 islands float within the Pacific. Within the Pacific Ocean lies an unusual island, an island that is more than twice the size of Texas and is earth’s largest landfill, the Great Pacific Garbage Patch (McLendon). Society is unaware that the excess use of plastic and other non-biodegradable materials has ended up in the middle of the Pacific Ocean and is the main source of ocean pollution. The solutions, ranging from manual clean-up to eliminating any further obliteration to the Garbage Patch, will reduce the amount of effluence the world has to endure.

Since the 18th century Industrial Revolution, approximately 1.6 trillion tons of carbon dioxide have been added to the atmosphere through the combustion of fossil fuels and deforestation (Harrould-Kolieb and Herr 378). The world’s oceans have absorbed approximately 30% of that carbon dioxide. This absorption has been beneficial in keeping that 30% out of the atmosphere, where it causes Climate Change, but it has a negative impact on water quality. When carbon dioxide reacts with water, it forms carbonic acid. In the oceans, carbonic acid releases hydrogen ions which increase the acidity of the water. Because of human action, the acidity of the ocean has risen 30% since pre-industrial times and by 2050 ocean acidity is projected to be the highest in 20 million years (Harrould-Kolieb and Herr 379).
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.
Saving marine ecosystems is an important environmental issue that biologists and scientists are studying today. This issue is frequently debated and addressed by several government and nonprofit organizations due to its important impact on human health and well-being. Global warming has complicated the issue because it is causing the oceans to warm up and carbon to be absorbed by the oceans. Reckless and indiscriminate human activity has led to the pollution of the oceans and a decline in the populations of marine animals worldwide. As the apex predator, we need to make a change by conserving marine habitats and ecosystems throughout the world. The Marine Conservation Institute is already trying to create environmentally protected areas by safeguarding marine ecosystems on a global scale. Being eco friendly can also save you money. Doing so will limit further damage to the environment and protect marine ecosystems.
Our ecosystem is in danger. Fish, corals, octopuses, turtles, and even whales are dying. One may ask why: humans. Humans are wiping out multiple ecosystems on a daily basis. If this atrocious rate of marine life genocide continues, the human race probably won’t be able to have fish on their dinner plates in approximately a hundred years. The water is murky, and life is fading away. Several factors act as a cause for this catastrophe. For example, the annihilation of marine organisms is kindled by pollution, overfishing, factory fishing, bottom trawling, global warming, and whaling.
Global warming is the gradual rise in temperature and oceans due to recent human activity. This is created by the production of too much carbon dioxide that is released into the earth’s atmosphere. The carbon dioxide, also known as a greenhouse gas, remains in the air trapping heat and gradually warming the planet. Other greenhouse gases such as: methane, nitrous oxide, and water vapor also contribute to this slow warming. According to Live Science, The state of these gases being trapped is called the greenhouse effect, which is one of the leading causes of global warming (Lallanillia). All the gases are created differently and have different effects on the earth. As for some greenhouse gases can be in the atmosphere for a short amount of time, other gases can remain in the atmosphere for thousands of
