Among the many types of ocean pollution, microplastic in the ocean is also a huge concern not only for the environment, but also for all marine life. TOXIC: Garbage Island is a documentary that focuses on microplastic in the ocean. The research team took a seven day voyage to the North Pacific Gyre which is the ocean’s “dump.” Most of the trash that sails with the waves in the ocean is plastic, plastic that never fully disintegrates. Overtime, the plastic will break into individual polymers less than or equal to five millimeters in diameter (microplastic) that still floats in the ocean. The problem with this is the pieces of plastic photograde to polymers and can be accidentally ingested by marine animals. These polymers then make their way up the food chain and eventually back to us. “Microplastics as vectors for bioaccumulation of hydrophobic organic chemicals in the marine environment: A state-of-the-science review” is a scholarly article that also focuses on the impact of microplastics on the aquatic life by presenting many laboratory studies. “Props 65 and 67: Stop profiteering from polluting the Golden State” is an editorial by “Los Angeles Times” that talks about the ban on plastic bags in the state of California because of the harm to the sea creatures. “Flotsam and fashion: recycler of 'ghost ' fishing nets makes marine litter trendy” is another article by “The Guardian” that talks about how fishing nets that are floating in the ocean are turned into apparel for
The effect of microplastics on our oceans marine life is indirect and therefore less obvious. Unlike microplastics, standard trash can directly harm animals by suffocating birds or imitating food. Microplastics play no direct threat to marine life, however, their long-term effect on clams, oysters, and other filter feeders will surely cause long-term catastrophe to our marine food web. So that brings us to the overlying problem, tiny microplastics and microfibers in our oceans created by a society built on synthetic materials are causing huge negative effects in our ocean's food webs. By bringing awareness to all these factors solutions can then be formed.
Plastic Pollution has become a global issue in our oceans. Although we hear about this from time to time the problem has grown tremendously beyond our knowledge. There are a growing number of animals dying each day due to plastic particles that either get stuck around their head, or that they swallow. If we do not stop plastic pollution in our oceans the ocean will eventually lose its habitats and our ecosystem will be changed forever.
In the National Geographic article “Eight Million Tons of Plastic Dumped in Ocean Every Year”, author Laura Parker expresses how violent the simple act of dumping trash into the ocean really turns out to be. This article goes into depth telling exactly what plastics pollution is causing, where it’s mostly coming from, and what you can do to decrease this problem and help save both our planet and ocean wildlife.
The problem with plastic ending up in the ocean is that marine life is being harmed by the presence of it. A study done on the harbor seals in the Netherlands found that more than 12% had plastic in the digestive system (California Coastal Commission). The list of affected species indicates that marine debris is affecting a significant number of species. It affects at least 267 species worldwide, including 86% of all sea turtle species, 44% of all seabird species, and 43% of all marine mammal species (Save our shores). The problem is underestimated because the marine life that ingests plastic or dies from entanglement often goes undiscovered due to the vastness of the ocean, as they either sink or are eaten by predators before they are discovered (Plastic Debris). The potential harm from ingestion of plastics is not restricted to seabirds. Plastic bags drifting on ocean currents resemble the prey of turtles. There is evidence that their survival is being hindered by plastic debris with young sea turtles being vulnerable (Ocean pollution). Over the past 20 years polychlorinated biphenyls (PCBs) have polluted marine food webs at an increasing rate, and are prevalent in seabirds. Though their adverse effects may not always be apparent, PCBs lead to reproductive disorders, increase the risk of disease and alter hormone levels. These chemicals have a detrimental effect on marine organisms even at very low levels and plastic pellets could be a route for PCBs into marine food
In the article, "Plastic in Our Oceans", Kimberly Amaral discusses the everyday uses of plastic and how it can be beneficial to humans, but harmful to marine life. As fishermen casually dump waste overboard, animals mistake it for food sources, such as a turtle mistaking a plastic grocery bag for a jellyfish. From the trash brought out to sea, gyres, large circulations of water, carry the garbage through currents, spreading it to all over the ocean, specifically to the central gyre. Amaral notes common ways for marine life to die from plastic, which include entanglement by plastic rings, consumption of plastic bags and pellets which stuff the intestines and lead to health problems, and suffocation. As researchers today work hard to discover
In 1988, it was determined that the United States alone, was producing 30 million tonnes of plastic per year (Derraik, J.G.B., 2002). This can be compared with the global and annual production of 260 million tonnes of plastic as of 2012 (Pearson, E., 2014). Plastics are lightweight, durable, and cheap to make. This makes them incredibly easy to sell and manufacture. However, these attributes are many of the reasons why plastics are the most prominent type of marine debris, and why they are a serious hazard to various ecosystems and the organisms that live within them (Derraik, J.G.B.,
One of the issues that is currently harming the ocean is the presence of pollution. Studies have shown that over the past thirty years, people have increased their use of plastics and synthetic materials and recently it has become even more abundant (Laist). The amount of plastic debris that has entered the ocean is partially due to people 's inability to properly dispose of plastic and waste. This has immeasurable effects on the physical ecosystem, as well as the creatures who inhabit it. While plastic is very buoyant, it takes a very long time to degrade, and it is usually eaten by
Plastic comes in innumerable shapes and sizes; it is used for various purposes. We use it to bag our groceries, pay with it, drink from it, occasionally eat off it or unwrap it to get to food, etc. The functionality of plastic is continual and surrounds us, so what is the con of plastic? When plastic cups, bottles, and bags are abandoned in the street, the wind transports and the rain seizes them into storm gutters, tributaries and eventually the ocean. When rubbish and plastic originate from terrestrial territory and enters the sea it is swept away by an eddy vortex called the North Pacific Gyre. Charles Moore discovered the North Pacific Gyre, or also known as “The Great Pacific Garbage Patch” in 1997. This garbage patch stretches hundreds of miles off the shoreline of California and Hawaii. Scientists estimated its size to be twofold the size of Texas or maybe even more substantial. This garbage patch contains some ten million tons of litter. According to Lindsey Blomberg, who wrote the article titled The Great Pacific Garbage Patch, writes, “What is known for certain is that the marine debris in the North Pacific Gyre is 80% plastic and it's mostly coming from land.” (1) Although the trash is in the ocean, it not only affects us but, wildlife on land or in sea too. Furthermost of the waste in the ocean consists of "microplastics" which according to Kitt Doucette, who wrote the article titled An Ocean Of Plastic is, “Larger chunks of waste that have been reduced to tiny
It is not just marine animals, from planktons to whales, which ingest microplastics. It can end up in humans when they eat seafood.
Microplastic is used in so many types of beauty products all over the world. Lots of Microplastic gets washed down the sink and into the ocean. People don't think of this because of the mental thought 'out of sight out of mind'. But Microplastic is causing many problems to many oceans and great lakes. This will affect the aquatic food chain from the tiniest plankton to us humans.
Concern over increasing quantities of marine microplastic pollution has increased substantially in the last decade, becoming a focus for many local and national governments, intergovernmental organizations, environmental advocacy groups, and the private sector. In financial terms, conservative estimates place the harm to marine ecosystems at $13 billion annually. While the available literature on microplastic pollution impacts has grown due to this increased interest, research into the subject is at an early stage relative to other areas of inquiry. Further, research into the effects and sources of microplastic uptake in marine environments have been largely dependent on laboratory experimental studies, due the technical difficulties in analyzing microplastics in the field. This paper sets out to describe the ecological impacts of marine microplastic pollution as they are currently known: the various types of microplastics and their distinct potentials for environmental harm; the sources of and vectors for microplastic contamination; known effects on marine organisms; and concludes with a discussion of legislative/regulatory solutions to date and potential next steps.
A rapidly increasing, long-term threat (SPME-LTT-sciencedirect.com) This article shows the effects of plastic in an ocean ecosystem and other water sources. Synthetic polymers in the marine environment also details how plastic in marine environments has consequences not just for marine animals at the surface, but for marine organisms in the

We 're treating the oceans like a trash bin: around 80 percent of marine litter originates on land, and most of that is plastic. Plastic that pollutes our oceans and waterways has severe impacts on our environment and our economy. Seabirds, whales, sea turtles and other marine life are eating marine plastic pollution and dying from choking, intestinal blockage and starvation. Scientists are investigating the long-term impacts of toxic pollutants absorbed, transported, and consumed by fish and other marine life, including the potential effects on human health.
With the combination of polymers that don’t biodegrade and mass overproduction, companies are harming the environment in severe ways. Plastic, a material seen everywhere, is a polymer made from oil. It is mass produced to make everything from shampoo bottles to automobiles and does not biodegrade. When it is eventually thrown out, the waste usually finds it way into the ocean, where it is either buried under sediment or eaten by marine life (Weisman 287-295). Creating a material that will ultimately kill marine life will undoubtedly wreak havoc on the
