Introduction The British Petroleum (BP) oil spill in the Gulf of Mexico was one of the worst ecological catastrophes in human history, causing vast damage to a fragile and beautiful ecosystem while at the same time calling attention to the deficits in current approaches to energy prospecting, risk management, and cleanup. This analysis of the Deepwater Horizon explosion and oil spill will devote attention to the following questions: (a) What kind of technology is in use for deep-sea oil extraction, what are the factors that accounted for the BP catastrophe, what were the statistical components of the spill in terms of volume and concentration, and what was the spatio-temporal scale of the oil spill? (b) What were the environmental (physical, biological, hydrological, and atmospheric) impacts of the oil spill, in addition to the economic and social impacts? (c) What were the scientific, technological, and policy solutions implemented by various actors to pursue the cleanup of coastal areas, wildlife, and wetlands damaged by the oil spill? (d) What is the feasibility of long-term biodiversity conservation measures and the limits of such solutions? Overview of the Spill The BP oil spill began with the explosion of the mobile offshore drilling unit known as the Deepwater Horizon, then operating in the Macondo Prospect Oil Field some 60 kilometers off the coast of the U.S. state of Louisiana, on April 29, 2010. The leak was capped on July 15, 2010, with a repair to the underwater wellhead ruptured by the Deepwater Horizon explosion. Thus, the BP oil spill lasted for about three months. During this time, roughly 5 million barrels of crude oil leaked from the wellhead into the Gulf of Mexico. The flow rate was not uniform, beginning... ... middle of paper ... ...hmann, L. (2009).

Summary and Response to Barbara Kingsolver’s “Called Home” In “Called Home”, the first chapter of the book Animal, Vegetable, Miracle: A Year in Food Life, Barbara Kingsolver presents her concerns about America's lack of food knowledge, sustainable practices, and food culture. Kingsolver introduces her argument for the benefits of adopting a local food culture by using statistics, witty anecdotal evidence, and logic to appeal to a wide casual reading audience. Her friendly tone and trenchant criticism of America's current food practices combine to deliver a convincing argument that a food culture would improve conditions concerning health and sustainability.
Humans are damaging the planet to live comfortably, we must change the way food is distributed worldwide, support local farmers and switch to a healthier diet in order to stop global warming. The current global has been getting better for us humans over the years, from eating bread and eggs 3 times a day in the XV century, now we can eat better than the kings of those times, however the much of the food in not healthy and the global food system still fails in getting food to every individual in the planet and in addition it contributes to the destruction of our world. Ms. Anna Lappe explains how the food system contributes to around 1/3 of the global warming issue in her essay “The Climate Crisis at the End of Our Fork”, while a group of Plos one explains the issues about the export and import of food growth over the last 50 years in the
April 20, 2010, a tragic disaster struck the Gulf Coast. British Petroleum deepwater Horizon oil rig cracked from three places and raw oil leaking into the sea. .it was considered that over 60,000 barrels of oil a day are mixing with Gulf water and Oil spread over 70 miles to 130 miles into the sea and can be seen from space.
The Exxon Valdez and the BP oil spill were caused by different disasters but had just as great of effects. On March 24, 1989, the Exxon Valdez oil spill began to reek havoc on the Pacific Ocean. The oil tanker, Exxon Valdez, left from Valdez, Alaska and was headed for Los Angeles, California. The tanker ran aground on Bligh Reef in Alaska. After six hours of being grounded, the Exxon Valdez spilled about 10.9 million gallons of oil (53 million gallons aboard). The BP oil spill occurred a little differently. On April 20, 2010, the Deepwater Horizon oil platform exploded and caused the largest marine oil spill in history. The platform sank about 5,000 feet underwater. The BP oil spill poured 4.2 million barrels of oil into the Gulf of Mexico. These oil spills are largely compared but were cause by completely different events. They had similar effects/damage, however.
The Ocean Ranger The Ocean Ranger was an offshore exploration oil drilling platform that sank in Canadian waters 315 kilometres southeast from St. John's Newfoundland, on the Grand Banks of Newfoundland on February 15, 1982, with 84 crewmembers onboard. The Ocean Ranger was the largest semi-submersible, offshore exploration, oil drilling platform of the day. Built in 1976 by Japan's Mitsubishi Heavy Industries, it operated off the coasts of Alaska, New Jersey, Ireland, and in November 1980 moved to the Grand Banks. Since it was so big, it was considered to have the ability to drill in areas too dangerous for other rigs.
An unnatural disaster that affected the ecosystem of Louisiana was the 2010 Deepwater Horizon oil spill. The BP (British Petroleum) oil s...

On April 20, 2010, the Macondo wellhead BP pipe leaked crude oil and gas on the ocean floor into the Gulf of Mexico 42 miles off the Louisiana coast (Gulf Oil Spill). This oil spill is known as the largest spill in U.S. history. The pipe was located 5,000 feet underwater where there are temperatures just above freezing and extremely high pressures (Gulf Oil Spill). Oil spewed from this pipe non-stop for 87 days (Gulf Oil Spill). About twenty percent of it ended up on the ocean floor or on the surface (Gulf Oil Spill). Since it’s hydrophobic, the oil on the surface spreads out and forms slicks. These slicks greatly affect ecosystems and animals. The oil that didn’t end up on the floor or surface hovered in the middle of the ocean, forming layers of oil (Gulf Oil Spill). All 200 million gallons of crude oil mixed throughout the ocean and affected coastal and deep-sea sediments (Gulf Oil Spill). Although the pipe was capped on July 15, 2010 (Gulf Oil Spill), much of the oil still remains on the Gulf floor today.
While militarily, the Gulf War of 1990-91 seemed like a quick and decisive victory, it was an environmental disaster, both at the time and when considering the residual impacts. Environmental travesties were committed by both the Iraqi aggressor and the allied forces, ranging from use of minerals like depleted uranium in weapons to deliberate dumping of oil into the Gulf. Oil fires and spills had a severe impact on all forms of life, most prominent in the Gulf region, but with possible global implications. Human health, wildlife, natural resources and ecosystems were all adversely impacted by actions taken and not taken by both sides of the conflict.

There are many causes to petroleum in b the oceanic environment. Oil naturally seeps into the ocean but the natural concentrations have been greatly exceeded. Shipping oil from one place to another contributes the most to oil in the ocean. The crude oil from transportation b is discarded into the ocean while cleaning bilges, which are the lowest compartment in ships, and transferring oil from tank to tank at sea. “Disasters like shipwrecks, oil tanker accidents, and offshore oil rigs fires continue to this problem, as does the disposal of urban garbage into oceans, dumping of waste oil by passing ships, commercial coastal and off-shore entertainment, and deep-sea industrial and nuclear waste dumps”(“Marine Water Quality”). Another large polluter is the oil industry. Tanker ports and refineries are located by the coast for shipping purposes. The coastal areas receive considerable damage from the spills. “Large numbers of seabirds are killed annually, their oil-matted plumage making flight impossible and exposing them to hypothermia. Oil-soaked fur of marine mammals loses its water repellency, also leading to death by hypothermia. Ingestion of oil by fishes, birds, and mammals may also result in death”(“Marine Pollution”). Another source of petroleum pollution is from the city streets. Oil runoff from urban streets and sewers enter waterways and the ocean. Oil has a very long term ecological impact on the ocean and the marine ecosystems. “The presence of oil in marine waters severely degrades water quality by clogging an animal’s feeding - structure, killing larvae, and blocking available sunlight for photosynthesis”(“Marine Water Quality”). Petroleum pollution has been a large problem for a very long period of time. “As early as 197p, oceanographic ecologists noted that they could rarely pull a net through the surface of the ocean without collecting some form of tar or
In the three months that it took to finally put a stop to the leak, 4.9 million barrels of oil were released into the ocean. The spill caused considerable damage to marine and wildlife habitats and the Gulf’s fishing and tourism industries. The White House energy advisor, Carol Browner, goes as far as to say that the Deepwater oil spill is the “worst environmental disaster the US has faced”. The Gulf of Mexico oil spill has had an extremely negative effect on the surrounding wildlife and ecosystem. Oil spreads across the gulf, contaminating any living organism that comes into direct or indirect contact with it.
“Since oil was found, tens of thousands of acres of wetlands have been devoured by the ocean. Sixty percent of Louisiana vanishes every year due to oil companies” (Grisham 257). “In 1970, the Fish And Wildlife Service listed the brown pelican as an endangered species throughout its range”
One of the most famous pollution threats of the bay was the Oil Spill of 2007. A tanker hit the wall of the bay, and a total of 58,000 gallons of oil was spilt into the water of the San Francisco Bay Area. The spread of the oil was so severe that the governed of the States came to see the progress that he inducted during the cleanup. Initial investigation of the extent to which the spill had affected the ecosystem of the San Francisco Bay area took twelve hours. There are the different conclusion that was arrived at after the
On the summer of 2010, the petroleum industry was shaken by one of the largest disasters in history known as the BP Deepwater Horizon Oil Spill. This resulted in the killing of eleven people, injuring of seventeen and an immeasurable damage to the ocean and the surrounding communities. BP had to immediately respond to the crisis and handle their financial and reputational risks.
