A spill in any of the deep sea areas would reduce the biodiversity of that area through reductions of bird populations, fish-stocks and populations of marine mammals. All of which are already under severe threat of over fishing and habitat disturbance without this imposed threat. Furthermore the contamination of coastal and coral ecosystems will all lead to to damage on the livelihoods of fishermen and people involved the local tourism. The 2010 Deepwater Horizon oil spill in the Gulf of Mexico has been described as the worst environmental disaster in the United States, releasing about 4.9 million barrels of crude oil making it the largest accidental marine oil spill. Most of the impact of this was experienced by the marine species.
These emissions can become acid rain and if it can damage a tree, it can and does damage coral. According to the Coral Reef Alliance; the world’s oceans have had “approximately 525 billion tons of carbon dioxide” dumped by human activity within their waters. [ (Coral Reef Alliance, 2012) ]. The site also goes on to state that the destruction of Mangroves,(which have been harvested for lumber) and the loss filtering saltwater swamps due to farming have caused quite a bit of stress on coral reefs. Then there are the odd ways we humans go about “enjoying the ocean”.
Fracking also created huge natural losses such as it crates pollution, destruction of forests to create its pipe lines. The pipe lines they use are also not long lasting as there is gas vapors in water because of leakage in pipe lines. From every twenty pipe lines, one is leaking that increases pollution. Gas burners used to store natural gas creates noise pollution more than a jet engine. It also have connection to increasing sexual diseases.
One con is that there will be many jobs at the mine, but just not nearly as many jobs that Bristol Bay employs in the salmon industry. Another, and possibly the biggest, disadvantage of building the Pebble Mine is the negative effect on the environment in Bristol Bay. Although the company managing this says that there will be a bad affect on the environment, history tells us otherwise. We can look at the Mount Polley gold mine disaster. In this environmental disaster, 10 cubic meters of water and 4.5 million cubic meters of potentially toxic slurry were spilled into virtually untouched forest, lakes and rivers.
Beach closures have also been more frequent being something many families, and residents have once enjoyed. These toxic chemicals have been found in fish and wildlife, which have been deposited into the lake by manufacturing sites and other industrial companies. (Glutting, 2003)Runoff pollution, pollution that comes from a single location has also added to the lake’s devastation. Storm water, irrigation runoffs, sediments, fertilizers, and fecal matter deposits, are some of the discharges contributed by sewage treatment plants. These runoffs have contributed to the beach closures, and the unsustainable condition of biological life in the lake.
The result was not just the super heated earth, it also resulted in oxygen depletion, the acid rain falling would have also been toxic with the ash and other debris in the upper atmosphere falling with it, this would have created an event of ocean acidification, killing many of the organisms that could survive the low oxygen levels in a normally pH balanced body of water. Many of the organisms and animals that did survive were small, and most could thrive if not survive in a low oxygen, acidic environment. “The collapse of marine ecosystems at the end of the Lopingian was most likely triggered by a sudden and widespread flooding over all relict shelves, following maximum emergence of epicontinental seas around Pangea” (Yin, Zhang, Shang). Many marine animals that survived could produce their own food, or lived off of the organisms mentioned above. But these animals never fully recovered, even after thousands of years they never reached the numbers that they once had.
(History.com) Later on in the 1900 hundreds, there were several more reports of ships being hit by what was said to be a freak wave or rogue wave. One of the most famous ships to get hit by a rogue wave was the Queen Mary. In 1942 while carrying 15,000 American troops 608 nautical miles (700 mi/1,126 km) from Scotland during a gale, RMS Queen Mary was broadsided by a 92-foot (28 m) wave and nearly capsized. Queen Mary listed briefly about 52 degrees before the ship slowly righted herself. (live science.com) One of the most memorable rogue wave occurrences was on October 30, 1991.
During WWII there were over 155 Naval ships sunk by enemy forces, however one particular seems to bring out heavier emotions then others. USS Indianapolis was a Portland-class Cruiser of the United states Navy. Along with its heroic actions that played a major part in bringing WWII to an end it also suffered one of the most Tragic losses in US Naval history. The ship was launched 7 November 1931 and commissioned 15 November 1932 following the Washington Naval Treaty of 1922 that called for the building of six cruisers. She was 610ft in length and was able to complement 1269 officers and men.
When I go to the beach I see how dirty the water is there. I hesitate to swim in it. Lake Erie is a beautiful lake when it is not so dirty, and we should try and preserve it. If we don’t it will be become so polluted that it will be considered dead, this happened in the 1960s due to all the factories dumping waste in to the Lake. It was literally a dumping ground and it even caught on fire a few times due to the toxic wastes.
The air quality on the shoreline of Lake Huron is the worst in the south Ontario area. (Sivers, A, n.d) Sediment loading is known to high levels of deferred solids being washed into creeks and rivers and carried down into the lake. (Sivers, A, n.d) Sediment loading can also be caused by dredging which can cause a decrease in food source for the aquatic life. With having foreign vessels follow in and out of the lake from the Atlantic is also causing problems. With the vessels having foreign aquatic life attached to the bottom of the ship and also leaking fluids into the lake while passing through.
