Pollution And Its Effects On The Environment

Our oceans are vast and they are some of the most mysterious and diverse places on earth. They provide food and shelter for countless organisms, they also provide a key factor to life; water. Unfortunately, pollution is dangering Marine life and slowly destroying the oceanic ecosystem. We have always had this notion that because of the sheer size of the ocean, that dumping our trash and other toxins into the sea would have no major consequences. As we have seen, that is entirely inaccurate. Oil spills, floating trash, toxic spills are just some of the various factors that contribute to the pollution of the oceans (Heimbuch, 2009).

The oceans need to be protected because it is where life began and if not taken care of, life as we know it will end. The well-being of the ocean is constantly being threatened and needs to stop. When dangerous substances go into the ocean, ecosystems suffer and become endangered along with the lives of people and marine life. The importance of protecting and preserving the quality and biodiversity of the world 's coasts must be recognized because they are truly irreplaceable. If humans are not educated , and become careless about what is thrown on the ground or sprayed on lawns, disastrous effects follow when it comes to the condition of the ocean’s ecosystems, which can endanger life itself, leading to a problem only we can correct. There is historical evidence of ocean pollution, although the problem still shadows us today.

The chemicals from Industries can quite harmful depending on what 's flowing into the water. Releasing toxic liquids directly into the water affects marine life as is, but it can also change the temperature of the water, also known as thermal pollution causing animals and plants that can 't handle that temperature to eventually die. Land run off usually happens when rain or perhaps a flood carry a harmful pollutants, which include fertilizers, petroleum, and waste from animals. One of the major sources of ocean pollution would be oil spills that can come from Ships. However, oil is not only extremely toxic, but it is very difficult to clean up. Unfortunately when there is a spill people may try to clean it up as best as they can, but a good amount will stay. Ocean mining can be extremely harmful to the ocean. They use ocean mining to drill for silver, gold, copper, cobalt and zinc, however in doing so they create sulfide deposits deep down in the ocean causing long term effects to the area. Finally, littering is another huge source of ocean pollution. Such things can include debris, especially plastic, which never goes away.

Everything in this world we use comes from the ocean in some way. The air we breathe, the water we drink, even the products we use day to day, would not be possible without the ocean. That's why the issue of ocean pollution is so important and needs to be addressed as soon as possible. We depend on the ocean for so much in our life, without it we would surely become extinct. People seem to think that since the ocean is so large and vast, we can dump as much waste as we'd like into it and it will never have an effect on us. However, since we've been polluting the ocean as far back as Roman times, the evidence of ocean pollution becoming a major problem is all too clear.

According to “Raw Sewage” by Judith Gradwohl, it states, “Around the world, untreated sewage flows into coastal waters, carrying organic waste and nutrients that can lead to oxygen depletion, as well as disease-causing bacteria and parasites that require closing beaches and shellfish beds.” This shows that many beaches are unavailable, due to the extreme risk of assimilating awful diseases, which come from sewage dumping in the ocean. Additionally, as a result of high levels of bacteria in the ocean, 2400 beaches were closed in 1993, just in the United States alone (Ibid). The diseases that can come from the contaminated sewage water include: viral hepatitis, cholera, typhoid fever, and a range of stomach and intestinal diseases (Ibid). Along with humans getting extremely sick from bacteria in the ocean, marine life can die from bacterial decomposers taking away oxygen in the

Dating back hundreds and hundreds of years ago, the act of dumping into waters has been practiced without any thought into the possible damages this could inflict on the ecology of the marine life present. The dumping of garbage and sewage in these waters is detrimental to the species that inhabit it, it can destroy their habitat, and it can destroy themselves as organisms (Chenery AM. et al. 2005). Since these organisms are usually fully submerged in these waters, there is nothing protecting them from being surrounded by polluted waters that could potentially harm them. For the past couple of decades though, and in many areas of the world, people have begun to notice and understand these problems and have begun setting out laws and required permits to do anything remotely close to dumping in waters (Chenery AM. et al. 2005). However, this is only but a single step in a process working towards cleaning and keeping both oceans, and in-land bodies of water, including their organisms, safe from human waste.

D. Chemicals and foreign liquids are not the only factors causing harm in the ocean. Many tangible objects, especially plastic, glass, and other trash, contaminate the deep blue sea.

For the last few decades hundreds of human activities have been severely impacting one of our most important ecosystems and the life it sustains. Ocean Pollution also known as Marine Pollution is defined as the spreading of deleterious substances such as human, industrial, and agricultural waste, oil, plastic, chemicals and much more. An article from the NOAA states “Eighty percent of pollution to the marine environment comes from the land.” Humans are responsible for the destructruction of the oceans, therefore it is our obligation within every citizen in playing there part to keep our oceans clean. Ocean Pollution doesn't only affect marine life, but us as well. An article from PlanetAid.org states “It provides over 70 percent of the oxygen

An additional large cause of ocean pollution that is not as widely known as other sources; because, many consider it under the category of “ocean dumping” but in reality it is it’s own category of garbage dumping. The title given to this cause may be misleading as it is “...human waste and sewage water that has been partially treated or untreated...” entering the ocean. It is polluting the water directly like chemicals that are dumped. There is another name for this, sludge dumping, this is the less scientific term. Not all causes are related to directly dumping toxins and waste into the

This does not only spill toxins into the ocean, but it also is killing marine animals. Animals who occupy the ocean mistake trash dumped into it as food. Therefore, these animals are killed from eating the garbage that is spilled into the ocean. An example of this is seabirds mistaking plastic for food. “Over one million seabirds are killed by plastic waste every year, and over one-hundred thousand sea mammals are killed per year due to pollution” (Gifford). Recycling can also contribute to saving the lives of many animals, such as the seabirds, but garbage dumped into the water is not the only form of pollution in

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.

Although the ocean covers approximately two thirds of the Earth’s surface, it is surprisingly susceptible to human influences. The effects of rubbish dumping have tainted our oceans and they have taken their toll on the vast marine environments and the populations in which they contain. Rubbish dumping involves depositing all the waste materials from factories and industries, tankers and ships and sewerage waste materials into the oceans and seas. In the report “Causes and Effects of Ocean Dumping”, the author Sharda states that “The wastes that are dumped into the oceans tend to have toxic substances which soak in all the oceanic oxygen. This

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.

Another cause of marine pollution is the discarding of garbage into oceans, rivers and dams. The situation is a major problem causing harm to marine life and ecosystems all over the world. Old

Around half of all ocean pollution is caused by sewage and waste water. Each year, the world generates perhaps 5–10 billion tons of industrial waste, much of which is pumped untreated into rivers, oceans, and other waterways.
