People are not only affected by the ocean, the ocean is also affected greatly by people. Firstly, human development, such as the construction of a river or a dam, can change the ocean geologically. The reason behind this is that the Earth’s ocean is all connected with multiple basins. Secondly, human activities, such as diving, can affect the ocean through the unnatural invasion of the marine environment without proper knowledge of what to do. Thirdly, the ocean and its inhabitants are greatly affected by marine pollution.
Many marine mammals mistake these for food (Greer, Abigail). Plastic kills fish, birds, marine mammals, sea turtles, destroys habitats, and affects animal mating rituals, which can result in devastating results, such as wiping out an entire species (“How Ocean Pollution Impacts Marine Life-and All of
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
Border. Weak U.S. border enforcement has led to high undocumented immigration. Increased undocumented immigrants have led to increased border patrols and the building of fences. Enforcement strategy has been strengthened and urban entry points fortified. For decades we have increased our border security, but to no avail.
How the oceans may die is crucial to understand in order for them to be preserved for the survival of the planet. Numerous human activities generate a staggering amount of grave complications for the oceans and its crucial marine life. One of the most direct human activities that causes rapid decline in marine populations is overfishing. Some of the species
Believe it or not we are all a witness of watching someone litter, or us littering. From planktons, to dolphins to birds can be affected by a simple oil spill in the ocean and especially in a close area like the Persian Gulf can cause great damage. When oil is spilled, toxins in the water spike and will shock the bodily systems of the animals living there, causing a massive amount of death and leading to endangerment. Before disaster had struck in 1991, the Persian gulf has beautiful clean beaches, filled with marine life. Beautiful clear, lushes water.
This general presentation is fair to the problem, as the trash vortex does pose a great threat to aquatic life, and its pollution of the sea is far from desirable. However, different media outlets and people have reported on the issue differently, resulting in a great variety of ideas and myths surrounding the trash vortex. Firstly, the physical manifestation of the trash vortex has often been misrepresented. Journalist Nick Allen’s article in the Telegraph, published in May 2010, described the garbage patch as a “vast floating island of trash”. This directly contradicts much of the information given by other reliable sources.
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.
This tells us that the main cause of plastic waste in the ocean is the inability of common people to dispose of their waste properly. Also, sewage or polluting substances that go to the ocean from rivers and different bodies of water are contributing factors. Plastics even have chemical nutrients that go to the ocean’s ecosystem. The chemical nutrients reduce the oxygen level of the ocean that affects plants, animals and ocean life. Waste is thrown directly into the ocean causing a huge
Ocean acidification is killing off the oyster population, which is also affecting the jobs in Washington. Initially, ocean acidification is when acidic gases are emitted into the air and absorbed into the ocean. According to the video Ocean Acidification by NOAA, ¼ of all the carbon dioxide release into the air is absorbed into the oceans. Some major contributors to carbon emissions are automobile gas and factory emissions. This is a problem in the Pacific Northwest because acid sinks to the bottom, but Pacific winds bring acidic water up from the bottom near the shore by the shellfish.
Around 150 years ago, humans started releasing fossil fuels into the atmosphere during the industrial revolution. The ocean takes up a quarter of the gas that surrounds earth by absorbing the CO2 we put in our atmosphere. Scientist thought the ocean was a great resource for getting rid of these CO2 gases in the atmosphere; however, they didn’t know how much these gases where destroying our great ocean. NOVA’s documentary presents, Lethal Seas, a documentary of the destruction of our vast ocean, concentrating on the American northwest coast, Papua New Guinea among the volcanic islands of Milne Bay, and Aurora Australis. The documentary dresses the issue of rising acidity levels in the ocean and its effects.
In conclusion, manatees are becoming extinct because people are populating the water that manatees live in which is causing them to die. Manatees are being struck by boats when people drive through shallow water too fast, because they cannot see them in time to move out of the way. Manatees are also becoming extinct because they are eating toxic algae that is produced from the
