Ocean covers 71 percent of the world 's surface and holds 97 percent of the total water on Earth. For centuries, people have regarded it as an inexhaustible resource and a useful transport route. The ocean also plays a significant role in regulating the climate, the atmosphere, carbon cycling, and nutrition flow. However, environmental problems, particularly over the last few decades, have pushed the ocean to its limits. This essay will argue three major environmental issues impacting the world 's oceans by focusing on the present condition and phenomena of these problems, possible reasons or factors, and lastly, damage to the ocean environment. Plastic threatens the diversity of marine life and affects the ocean 's ecological circulation. Plastic is a large part of ocean waste, and its proportions continue to grow. Under natural conditions, general plastic decomposition needs 50 to 70 years. However, some plastics take hundreds of years to decompose. Plastic floating in the ocean decomposes more quickly, but it still takes decades. Unfortunately, only one-third of produced plastic products are recycled and reused, and the remaining pieces fall into the ocean. The appearance of the Great Pacific Ocean Garbage Patch shows that, with the movement of ocean currents, a large number of plastic pieces have gathered together in the ocean. This increase in plastic seriously threatens marine biodiversity. According to José G.B Derraik (2002), the main threat comes from animals
Ocean pollution is caused by many things,plastic,humans, and oil spills, we are trying to stop this. So many people just put the plastic in the ocean and people are trying to stop them. Two billion people within 30 miles of the coast create 100m of coastal plastic waste. We can help by reducing plastic in waste stream, and try to stop pollution. Another way we can help is by recycling (Doc.1). We cause pollution to by dumping trash and garbage onto beaches. We have to help protect oceans by monitoring the water to see if people can go swimming (Doc.2). The oceans have to stay healthy because they are a habitat to animals (OI). Another reason we have to keep oceans healthy because they are a big food source for us (OI). In
Oceans cover approximately 75% of Earth 's surface and are vital to this planet and the people who inhabit it. Oceans provide food, natural resources, and recreation for nearly everyone in this world. Unfortunately Oceans have been receiving mass amount of pollutants including oil spills, toxic waste dumping, and industrial dumping. These pollutants will have negative impacts on the wildlife in the ocean, as we are seeing already with the Coral Reefs, and soon enough it will begin to affect our lives as well.
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.,
Over the few years, humans have discarded millions of tons of garbage into the oceans. Ever wonder where the cup you threw out this morning will end up? Or the plastic spoon you used for lunch? How about the cap of a water bottle? The calamitous plastic ends up in the water, taking thousands of years to decompose. The consumption of plastic by the marine life is perilous and the leading cause of death for life on shore.
Every year, millions of tons of plastic are tossed into the ocean, harming all types of marine animals as well as the environment. Hundreds of marine mammals like whales and dolphins are found washed ashore filled with bottle caps, plastic bags and basically anything they can swallow. Not only does plastic pollution harm marine life, but it affects the entire ecosystem. If a predator is dependent on a certain species for prey and the predator has a role in the environment, it is important for the prey to not be disturbed by pollution. If that species of prey were to go extinct, then the predator species could be seriously impacted as a result. These problems warrant the need for more research into the magnitude and causes of plastic
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
Plastic is a huge problem to the Earth’s ecosystem, including to the marine wildlife of the oceans. It gets into our oceans in large quantities, and they pile up to a point they become an “island of plastic.” Some of which are estimated to be as big as a few million square miles, the biggest being in the Pacific ocean. This could result in environmental issues that could harm the ecosystems of the oceans. It would be eaten in small quantities by fish and by birds, which could cause many health problems that could lead to death. This is a problem that will only lead us to think more critically the waste we produce as humans. In only of a short time span of 35 years, was the oceans transformed into a landfill of plastic.
In the documentary “Inside the Garbage of the World”, the main social problem being explained is that there has been a great influx of plastic and other type of garbage in oceans and their beaches. This buildup of pollution has largely affected the wildlife population ranging from animals on the beaches to the creatures of the ocean. In oceans, what is called ‘garbage patches’, a large buildup of garbage that flow to one area in the oceans, are being created. Approximately 50 percent of all plastic sinks to the bottom of the ocean floor but about 2 times that much is actually already on the ocean floor. In fact, according to the documentary, there is a garbage patch that is to the left of California that is the size of half of the United States. Each year, about 4.7 million tons of plastic goes in the ocean a year and it is estimated that by 2050, there will be another 33 billion tons of plastic added to the present amount. Eighty percent of the current pollution comes from the land. According to marine researchers, twice as much plastic debris is one the ocean floor than it was 10 years ago. In the futures, plastic will break down into smaller pieces of plastic, creating a bigger problem from the habitat. This plastic pollution is one of the leading cause for beach and ocean inhabiting creatures be extinct because animals are mistaking these plastic pieces for food. When scientist began to dissect beach animals such as birds, they discovered that at least fifteen pounds of
The oceans face many types of pollution every day, every second. The ocean is our greatest ecosystem and out most valuable resource. A common misconception is that the rainforests are the lungs of the planet however, the majority of our oxygen is made via the algae in the sea. The oceans feeds, hydrates, and provides us with oxygen; ironically enough, despite its monetary value to mankind, it is what is treated the worst. For ages we have been dumping our trash, chemicals, and waste into the oceans with no fear or regret, almost an “out of sight- out of mind” mentality. People once and still assume that the oceans are so vast that all of the pollution is diluted and would be dispersed through out, going unnoticed. However, dilution is a myth and an idea that renders ocean dumping to be less impactful. Even so much of the man made pollution is becoming even more concentrated and have entered our natural food chain. However vast the waters of the ocean are, they are not meant to house all of these external factors. There are many alternatives to marine pollution including recycling, finding alternative trash dump sites, cutting down on harmful chemicals for agriculture, and most importantly having the ability to recognize when a problem is developing and counter act, immediately.
Ocean pollution is one of the most urgent issues in our world today. The ocean is crucial to our ecosystem and it is being severely damaged at an alarmingly increasing rate. In this paper I will educate about the role the ocean plays in our beautiful Earth, why it is being so widely ignored and dismissed, the causes of pollution, and its effects on animals and humans alike.
This has been done over and over again throughout the years. All though plastic is biodegradable, it takes an average of 450 years for it to do so. Some bottles can take up to 1000 years for this to happen. By that time our planet will not be able to support such thing and will give up on us. Plastic usually breaks down into smaller and smaller pieces of plastic over the years before it to fully biodegrade. These tiny pieces of plastic are eaten by so many marine animals that live around them and every single animal that eats these tiny pieces are affected by it and many times die. All these tons of plastic don’t just disappear or get eaten by the animals though, they accumulate. The great pacific garbage patch is an example of this happening. This area is around 7 million tons heavy and twice the size of texas, it can also get 9 feet deep. Facts say that there is 6 times more plastic than plankton. In case you didn 't know, plankton is the main food for many animals living in the ocean, from small fish to the great whale shark depend on plankton to stay alive.
of the Great Pacific Garbage Patch, the exact size remains unknown. In addition, Doucette warns us that this patch contains more than ten million tons of waste. She describes the area to be a “fetid swamp of debris where tiny bits of decaying plastic outweigh zooplankton- one of the most prolific and abundant organisms on the planet- by a ration of six-to-one”(Doucette). It is now apparent that the amount of plastic particles residing in our oceans is damaging the natural habit and this trash is not going anywhere. Due to the currents in the ocean, plastic particles are
Due to their regurgitation ability; most studies have focused on the ingestion of plastic pollution by bird, this does little harm to birds used in the studies. The effects of ingestible plastic on fish have not been studied as thoroughly and no studies have been conducted on filter-feeding organisms, which do not possess a feeding mechanism which would allow them to distinguish between plastic and plankton. Plastic pollution is only getting worse due to increasing population of developing countries. A wide variety of marine species is known to be harmed by plastic debris. This could threaten the survival of certain species, especially since many are sadly endangered by other types of anthropogenic actions.
