Oceans, seas, and coastal areas are essential to the Earth’s ecosystem and are critical to sustainable development. Two-thirds of the earth’s surface is covered by oceans, seas, and coastal areas, and contain 97% of the planet’s water. The oceans contribute to poverty eradication, create sustainable livelihoods for the three billion and plus people depending on it, are crucial for global food security and human health, and are the primary regulator of the global climate. The Oceans contribute to human well-being because they provide us with water, oxygen, and many natural food sources. Although there are many groups of people who depend on oceans for sustainable livelihoods, they are the most vulnerable because they become so reliant on natural resources and are harming themselves without even knowing it. Oceans are increasingly threatened, degraded or destroyed by human activities, as this causes the oceans to reduce their ability to provide crucial ecosystem services. Important threats that …show more content…
Oceans are threatened daily by both natural and manmade pollution, as the largest factor affecting them is plastic. Over the last decade, there has been more plastic produced compared to the last 100 years (“How Ocean Pollution Impacts Marine Life-and All of Us”). Around 100 millions tons of plastic is produced every year and 10 percent of that plastic ends up in the sea. Many sources are the cause of ocean litter including trash that washes off city streets, waste blown in from landfills, and containers that fall off ships during heavy storms. Many marine mammals mistake these for food (Greer, Abigail). Plastic kills fish, birds, marine mammals, sea turtles, destroys habitats, and affects animal mating rituals, which can result in devastating results, such as wiping out an entire species (“How Ocean Pollution Impacts Marine Life-and All of

In Island Packet’s article “How plastic almost killed this Lowcountry sea turtle” by Delayna Earley, readers are informed about the discovery of a dead sea turtle that was recently treated at the South Carolina Aquarium in Charleston, South Carolina. The image is effective in responding to the rhetorical situation in which plastic debris are proven to be harmful to marine life and so articles like Earley’s are written to inform others about how damaging plastic is. The exigence of the article is about how plastic pollution is harmful for the ocean. Throughout the years, there has been an increase in the advocacy being mindful of plastic waste and on using less plastic materials.
Ocean Pollution DBQ Did you know that every year, eight million metric tons of plastic is dumped or somehow ends up in the ocean (Doc. 1)? The following sentences will talk about what people are doing to pollute the oceans and how they are making the pollution better. Humans are the biggest threat to animals in the ocean because they litter so much (OI). Sometimes, people litter without even knowing they're littering.
As the rate of plastic production exceeds the rate we get rid of it; it will soon overtake our oceans. In 2010 alone, it was estimated that over 300 million tons of new plastics were produced around the world, (QTD. By UC Davis USA on YouTube). Many oceans from North America and Japan are being polluted by our carelessness and are causing our marine life to suffer. Marine mammals such as seals are being found entangled in plastic fishnets and several drown.
This is an example of commensalism. Sadly in the ocean there is plenty of human destruction to talk about. Some examples are overfishing, which is a problem in 90% of the world’s oceans. tourism, development, shipping and pollution. As humans we are trying to not overfish by setting limits.
If wildlife’s ingestion of plastics caused by people’s improper throw of these materials isn’t enough of a burden. There are other ways that the wildlife are affected by plastic pollution. Such as entanglement, this is mostly common in marine life, such as fish, seals, turtles and birds. These animals get stuck in these debris and end up suffocating or drowning. Because they are unable to untangle themselves, they also die from starvation or from their inability to escape predators.
People are not only affected by the ocean, the ocean is also affected greatly by people. Firstly, human development, such as the construction of a river or a dam, can change the ocean geologically. The reason behind this is that the Earth’s ocean is all connected with multiple basins. Secondly, human activities, such as diving, can affect the ocean through the unnatural invasion of the marine environment without proper knowledge of what to do. Thirdly, the ocean and its inhabitants are greatly affected by marine pollution.
It is impossible to give an accurate estimation of the amount of plastic that is being polluted into the ocean. However, in 1975 the global fishing fleet alone dumped approximately 135 400 tons of plastic fishing gear and 23 600 tons of synthetic packaging materials
The topic of this research paper will cover over Ocean Acidification and the effects on marine ecosystems. Ocean acidification is the decrease in pH levels of the Earth 's oceans, due to overbearing carbon dioxide being brought by the atmosphere. The carbon dioxide is drawn by seawater, where the chemical reactions take place, which minimize the pH levels in the ocean, the carbonate levels and the important calcium carbonate which these sea creatures need. When carbon dioxide disperses in this ocean, it causes the levels of acidity to rise towards the the surface, where most shell growth in marine animals have been stopped and has created the cause of reproductive disorders in multiple fish. Part of the problem with ocean acidification is human activity.
When these actions are made, the wind may blow them into the trees, bushes, and even water sources including lakes, ponds, rivers and oceans. According to the movie Bag It, there was over 5 tons of plastic brought out of the one specific area in the ocean and over 100,000 marine life die per year. These oceans are so over crowded with plastic wastes, which do not decompose, that these animals have been eating it and dying because it will not properly go through their digestive system. Overall, if people opened up their eyes and realized the amount of damage they have created, then we would be able to fix ourselves and the environment in which we live in. Majority of the solution includes supplying your own bags, bottles and change your plastic tupperware containers to glass.
According to a Biological Diversity website (https://www.biologicaldiversity.org/campaigns/ocean_plastics/), the author states that “Thousands of seabirds and sea turtles, seals and other marine mammals are killed each year after ingesting plastic.” People keep littering and that littering is killing precious marine life. The level of
The ocean is nowadays undergoing numerous environmental issues that further lead to marine pollution. Marine pollution is a very serious environmental issue that most of the countries of the world encounter. Aquatic littering is considered as one of the major causes of marine environment. The misleading use of the marine environment is extremely impacting the marine life and ecosystems. Moreover, the total amount of toxins and debris discharged by human beings is incredibly increasing in today 's world.
The reason plastic is used in many products is because it can withstand up to tons of pressure per cm3, is cheap, is durable, and finally, there is no worry for discoloring. But these days, plastic is becoming a major problem the world has to deal with. Plastic is thrown into the ocean, and it is breaking down into very small pieces, and killing marine life, as they mistake those pieces to their prey. As a matter of fact, nearly all plastics are recyclable, but it 's the recycling companies ' machines that refuse to recycle that kind of plastic(eartheasy.com). I. Plastic, what have you done?
This cost for turtle a life, as plastic causes a blockage within digestive system. But this is only the beginning. Spots made of plastic cover for Sunlight cannot penetrate through plastic garbage into the water, algae and plankton, which is the bottom of the food chain, may simply die out. The situation can quickly turn into a global crisis. If it becomes less plankton, it means that fish and turtles will have nothing to eat, and if they begin to disappear, then the number of predators such as sharks and whales, also will be reduced.
Harmful fishing methods are unnecessarily killing turtles, dolphins, and destroying critical habitats. Global warming is increasing the temperature of the ocean water, reducing the generation of the base of the food web, plankton. The reducing of the plankton generation is causing major marine ecosystem change. Pollution is also a significant environmental issue HAL is facing. More oil reaches the ocean each year, a massive amount of oil has been accidently spilled from ships, which in turn is destroying animal and aquatic plant life.
“An average person takes about 12 steps before they litter. ”(“Eye-Opening Statistics”). This is a shocking statistic. An average person shouldn’t even litter, littering harms the environment in many ways. It harms the oceans, each year about 300,000 dolphins die because the government throws the trash littered into the oceans.
