From the sociological perspective, it was a huge social, cultural, economic and psychological threat for the communities living across the coastlines, cleanup workers, and especially children. Firstly, oil was released into the sea; it spread out on the surface of the water and contaminated the sea and coastlines. Statistics had shown that the Gulf oil spill killed 3,902 birds, 517 turtles, 71 marine mammals and more than thousands of other wildlife animals under the sea are covered by oil during or after the disaster (Merchant, 2010). Besides, the contaminated
Negative Effects of Ocean Pollution “Each day, oil used to lubricate engines and to power the vessel leaks into the ocean” (Wroble 44). When the residue enters the ocean, it begins to affect the environment and animals. This is just one of the many problems from ocean pollution. “According to Worldwatch research associate Peter Weber, 80 to 90 percent of all of the materials dumped at sea are dredgings...dredgings are rich in toxic chemicals...from nonpoint sources” (Wroble 49). One particular chemical that affects the oceans are Polychlorinated Biphenyls, or PCBs.
However, when the population of this specific kind of starfish increases at the Great Barrier Reef the reef “might be completely destroyed in two to three years”1. An invasion by these starfish causes devastation to the reef, as happened in 1970. Many parts of the Great Barrier Reef have been destroyed, and although the population of crown-of-thorns starfish near the reef is now negligible the reef still needs a long time to recover from this plague.2
Keeping the Ocean Free of Debris Pollution in the Persian gulf is negatively impacting marine life How much are we trashing our ocean? CNN, February 12th 2015. Arabian Gulf coral reefs dying a slow death. Gulf news, June 10th, 2014. Spill, Dolphin Deaths Spark Alarm At Persian Gulf Pollution.
Loss of coral reefs would be devastating to one of the most grand pools of biodiversity in the whole world They help seed the oceans and provide food to a complex web of organisms that lead all the way to man. They act as natural barriers to shorelines, and as they die, coastlines become more susceptible to damage and flooding; tropical storms and high waves would be the ones that could make the most damage if coral reefs were to disappear. Of course, not only we are the ones to be damaged by this, but other animals in the marine ecosystem too, like sharks. Sharks work in the ocean and in coral reefs by cycling nutrients between it and the open ocean, removing invasive species, and getting rid of weak fish carrying disease; if coral reefs were to disappear, then sharks would lose one of their main ways to obtain food and nutrients. And as we all know, if one animal disappears in an ecosystem, the organisms that consumed them would die and affect the food chain so
This has a myriad of impact in the marine ecosystem and well beyond. First, I would like you to understand the scale of this problem. A report from the United Nations (UN) estimates that nearly 52% of the world’s fish population is endanger of being exploited, overfished and eventually even depleted . If you think about the sheer size of the ocean and how many fish live in the ocean, this is a very concerning statistic. This is concerning for a couple of reasons.
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.
Salem Abdullah Alazmi S00036124 Dr. Buckton-Tucker ENGL 102-05 May/4 Annotated Bibliography The earth is surrounded with oceans, oceans covers around 70% of the earth. With this number of oceans, all of it is effect by pollution. Many animals that lives inside these oceans are effected from this pollution. Not only the animals but also people, that may cause death to some people and to some animals, some animals are extinct because of the pollution. Humans are the reasonable behind all of this pollution.
However, its size can be estimated to be between 270,000 square miles to over 5,800,000 square miles, meaning it is somewhere between the size of Texas to 8% of the Pacific Ocean. However, it is not very dense with 4 debris particles per cubic meter, which allows for satellite images or researchers on boats to aid our understanding of the Patch. As the Great Pacific Garbage Patch is so large, it naturally affects many living things: for example, the plastic waste we discard annually that ends up in the Patch can kill over 1,00,000 sea creatures according to a 2015 UC Santa Barbara study. Since the Patch is at the center of the North Pacific Gyre, it affects a plethora of different marine animals, ending up in their stomachs and poisoning their children as the plastics are long-lasting and can absorb toxic pollutants such as DDT, PAHs and PCBs. The consumption of these plastics can affect the entire food chain, poisoning the jellyfish who eat them, the fish who prey upon them, their prey, and so on.
Certain species have a huge impact to an ecosystem, but even the smallest fish could have the biggest impact. Overfishing occurs when more fish are caught than the population can replace through natural reproduction (overfishing). The results not only affect the balance of life in the oceans, but could also affect the coastal areas that depend on fish for their way of life. For centuries, our seas and oceans seem to be considered a limitless food supply. But that is not the case, increasing fishing efforts over the last fifty years as well as unjustifiable fishing practices are pushing many fish stocks to the point of extinction.
Another natural cause is oceans and hurricanes. Both the ocean waves and hurricanes accelerate erosion, which is a main cause to the marshes disappearing. Something New Yorkers should realize is that "80% of oil and natural gases produced in the U.S. travels through our marshes" as according to page 12. America 's economy could go so wrong if the marshes the oil processes through suddenly disappears. Also, a huge percentage of marine life loves in Louisiana 's marshes.
