Research from the University of California San Diego Scripps Institution of Oceanography said that species in the ocean consume a projected 12,000 to 24,000 tons of plastic every year in the Pacific Ocean (Nall, 2014). Pollution of recyclable materials in the oceans is one of the leading causes of why some marine species are nearing extinction. Many authors of articles and books analyzing this topic tend to agree that pollution of our oceans is a problem. The future of this problem is where their ideas tend to differ. The following four literature reviews attempt to demonstrate and support my belief that pollution is getting worse in the ocean and more marine life ecosystems are being affected, but there are things that we as humans can do …show more content…

Literature Review
Recovery of Marine Animal Populations and Ecosystems: Lotze, Coll, Magera, Ward, Airoldi
In a research article by Lotze, Coll, Magera, Ward and Airoldi (2011) they examine the positive side of how ecosystems in the ocean can recover even though they are faced with many different types of struggles every day. The authors ask the main question: How common is recovery among depleted populations and degraded ecosystems in the ocean? It is hypothesized that over the years, ecosystems are going to recover and essentially in the future, increase. The results in this study supported the hypothesis of the research on recovery for certain ecosystems and stated that 10-50% of ecosystems actually show some rate of progression (Lotze, 2011). This has significance when looking at pollution and the effects it has on marine life because: “Pollution controls and habitat restoration have had important roles in the recovery of diadromous fishes. Overall, in terms of relative importance of the different factors, it has been shown that 95% of recoveries of exploited marine species in estuarine and coastal regions were enabled by …show more content…

It is hypothesized that through laboratory studies, it will be provable that microplastic expansion has gotten worse over the years and is greatly impacting marine life. The results in this study supported the hypothesis of the research because it states: “Several million tonnes of plastics have been produced since the middle of the last century (more than two hundred million tonnes annually)”(Ivar do Sul, Costa, 2013). This has significance when looking at pollution because: “Microplastics are reportedly present on six continents, and higher amounts are commonly related to densely populated areas. In a study of the types (mostly fibers) and materials (frequently polyester and acrylic) of microplastics, suggested that the plastics were produced by sewage effluents, including wastewater from washing machines”(Ivar do Sul, Costa, 2013). These results indicate that pollution is present on six of the seven continents and it comes from largely populated areas. These results agree with the hypothesis that our “untouched and super-productive world” is affecting marine life ecosystems (Vannela, 2012). All of these results combined confirm the overall hypothesis that pollution is getting worse in the ocean and more marine life ecosystems are being affected, but there
