Offshore oil drilling has always been a notorious subject of debate due to the positive growth it can bring to a country’s economy and simultaneously bring detrimental effects in a marine environment. The largest issue regarding crude oil pumping offshore is the high risk of tremendous damage to marine ecosystems and depleting resource, additionally many modern economies count on crude oil as an effective power source and its growth in the financial market. Historically offshore drilling has had its share of enormous oil spills into many bodies of water such at the Lakewood Gusher spill, the Gulf War Oil Spill, Odyssey Oil Spill and unfortunately many more(Cooper,1992). These date as far back 1967 when Scilly Islands was documented as the first As a result many marine animals are at an increased risk of health issues from fatal compounds once they are absorbed a plethora of health issues arise such as ulcers, liver failure, kidney failure, increased infertility among species, and brain damage (National Oceanic and Atmospheric Administraion,2010).Another essential point is that oil rig accidents which occur on open water are much harder to clean up that oil spills on land since the material is spread along coastlines and coral reefs much farther by traveling atop the water thus taking longer for cleanup(Cooper,1992). Subsequently marine wildlife continues to ingest and absorb the crude oil which ultimately take a toll on their bodily functions (National Oceanic and Atmospheric Administration, 2010). Moreover, countries with a diverse marine ecosystem such as the country of Belize rely on tourism and fishing to generate much of their economy, an oil spill would mean that locals would have to find different sources of food since the fish will be contaminated and the tourist industry will take a huge hit which will take many years for it return to normal statistic and still not return to its original state (Cisneros-Montemayer, Kirkwood, Harper, Zeller, and Sumalia, 2013). It can be seen that oil extraction initially has a high amount of economical outcome, but it’s value decreases exponentially, yet tourism continues to boast a steady number of US$183 Million every year due to a wide range of environment tourism (Cisneros-Montemajor et al,
Because of BP oil spill all business around coastal beaches suffers a lot which are only depend on tourism and fishing. This destruction not only cause health problem, but also be responsible for millions of dollars in lost revenue.
There is an abundance of oil underneath earth’s crust on land and in the water but getting to that oil can be proven as a challenge and a negative impact on the earth. Many of these oil reservoirs lie in federally protected land or water to minimize the negative impact on the earth. But should those restrictions be removed? Removing the restrictions can allow the US to tap into domestic reserves rather than rely on imported oil from the Middle East and Asia but tapping these reservoirs can also leave behind an impact that is harmful to this planet. “Critics oppose this move for fear that it will cause irreparable harm environmental harm. They point to the April 2010 oil spill in the Gulf of Mexico as evidence of the risks associated with offshore drilling” (SIRS).
In today's global economy, energy is one of the most crucial and sought after commodities. Who supplies it and how much they supply determines how much influence they have over other countries as well as the global economy. This is why hydraulic fracturing is currently such an important and controversial topic in the United States. Hydraulic fracturing, more commonly known as "fracking" or hydrofracturing, is the process of using pressurized liquids to fracture rocks and release hydrocarbons such as shale gas, which burns more efficiently than coal. This booming process of energy production provides a much needed economic boost, creating jobs and providing gas energy for Americans. The efficiently burning shale gas reduces carbon emission from electricity production plants, reducing carbon footprints on the environment. However, the process of hydraulic fracturing uses millions of gallons of pressurized liquid, which contains toxic chemicals, and some of this water is left over undealt with. The air near fracking sites is often also polluted and unsafe for nearby community residents. Injecting millions of gallons of water laced with toxic chemicals into the rock thousands of feet deep can cause earthquakes, causing a safety hazards for all nearby areas. Hydraulic Fracturing makes rare natural gases easily attainable, boosting the economy and reducing carbon emissions. However, the negative side effects such as contaminated water and air, make hydraulic fracturing a process that may not be worth the benefits.
The U.S federal government should significantly increase fracking because oil and gas fracking is big business in America, with more than two million hydraulically fractured wells across the country producing 43 and 67 percent of our national oil and gas outputs, respectively. But in my opinion these wells also nearly played a secondary role as nuclear waste storage sites and had the Atomic Energy Commission had its way with Project Plowshare. And fracking is the process of pumping water deep into the Earth, specifically into underground oil and gas reserves, at tremendous pressures in order to break apart the surrounding rock and free the energy product, which can then be pumped out and used. However in the mid 1950s, scientists from the Atomic Energy Commission and officials from the U.S. Bureau of Mines did begin experimenting with an alternative method of fracking, one that employed nuclear bombs more powerful than anything we dropped on the Japanese.
As the head of Shell Oil Company, Marvin E. Odum argues for the expansion of offshore drilling in his article; making claims for the benefit of the United States. His article covers the fact that America has become highly dependent on imported oil from foreign countries and that this is no help to the economic crisis of today. With a few facts for backup, Odum discusses the benefits that the expansion of offshore drilling will bring to the United States. Being the president of Shell Oil, his credibility on the topic is undeniable, as he makes his argument for expansion.
Petroleum seepages, in some form or another have been around since ancient times for boat caulking, road mending, and as medicine, however, the modern petroleum industry was truly born with the first drilled oil well in August 1859 by Edwin L. Drake at Titusville, PA. (Laudon, 347) At first, in the United States, oil production was controlled by small operators but by the late 1870's John D. Rockfeller had purchased most of the nation's refineries-controlling the United States industry. The Sherman Anti-Trust Act of 1911 split Rockfeller's Standard Oil Trust into three smaller companies; today they are known as Mobil, Chevron, and Exxon. (Lynch, 214) Since that time, oil has become a major part of everyone's way of life. Oil is used to provide fuel for automobiles, tractors, trucks, aircraft and ships. Petroleum products are the basic materials used for the manufacture of synthetic fibers for clothing and in plastics, paints, fertilizers, insecticides, soaps, and synthetic rubber etc... (Lynch, 207) Due to this demand, companies are constantly searching for more oil deposits.
The environmental danger taken by offshore drilling is very straight forward, made clear by oil spills such as the recent BP oil spill and the Exxon Valdez oil spill in 1989 off the shore of Alaska. In the circumstances of the Exxon Valdez spill up to 250,000 sea birds died, over 2,800 sea otters and thousands of other animals], (figures from the BP oil spill are not yet concluded), having had a heavy strike on the regional wildlife and directing to a ban on all offshore drilling in America, until George Bush overturned it in 2008 to this repeal was a misjudgment because two years later there was the Deepwater Horizon spill. In this way, offshore drilling ruins ecosystems and fish supplies which creates a wasteland of a shoreline among southern USA.
Hydraulic fracturing, also known as Fracking, is a strategic system of obtaining natural gas that could be as deep as several thousand feet underground. Basically a mixture of sand, water, and chemicals are pumped underground at extreme pressures until they hit shale which contains the natural gas and in return the gas is forced up out of the ground. Fracking has become a highly successful process for increasing natural gas reserves in the United States. This process also lowers the United States dependence on foreign gas and oil and it accounts for an estimated forty two trillion cubic meters of natural gas, which is said to be enough to keep the United States in motion for sixty five years. As good as the fracking system sounds, there is always the down sides like the fact that the chemicals used to obtain the gas are extremely toxic. These toxic chemicals are pumped into the ground and can spread into nearby water. If this happens, the water will itself become toxic and undrinkable by neither animals nor humans. There are a lot of pros and cons of fracking, but what many people over the last few years have tried to say is that human life and safety is more important than an easier and cheaper way of doing something.
On April 20, 2010, the Gulf of Mexico experienced a disaster unprecedented in scale and environmental impact. Fifty miles off the coast of Louisiana in the deep waters of the Gulf of Mexico, a BP drilling rig suffered an explosion that claimed eleven lives and caused the rig to sink over 5000 ft. to the sea bed floor. This was the beginning of the BP oil spill which spanned over eighty seven days, releasing an approximate 2.3 million barrels of crude oil into the Gulf of Mexico. Although the flow of oil into the Gulf was contained July 15, 2010, the lasting effects of the oil spill on the environment continue to be devastating and widespread. (Kirkwood 1)
Because it is the most highly publicized of the different forms of ocean pollution, oil spills, oil leakages, and general oil contamination are something that we all seem to be aware of. Since the Exxon Valdez incident, the American public in particular has been more and more critical of oil companies.Each year, over 700 million gallons of oil end up in the ocean. Contrary to what you may have thought, most oil pollution doesn't come from tanker accidents. In fact, tanker accidents account for less than 90 million of the g...
“ Effects of Oil Spills on Marine and Coastal Wildlife” Holly K. Ober. WEB. 19 May 2014
" Oil is the life blood of our modern industrial society. It fuels the machines and lubricates the wheels of the world’s production. But when that vital resource is out of control, it can destroy marine life and devastate the environment and economy of an entire region…. The plain facts are that the technology of oil-- its extraction, its transport, its refinery and use-- has outpaced laws to control that technology and prevent oil from polluting the environment…" (Max, 1969). Oil in its many forms has become one of the necessities of modern industrial life. Under control, and serving its intended purpose, oil is efficient, versatile, and productive. On the other hand, when oil becomes out of control, it can be one of the most devastating substances in the environment. When spilled in water, it spreads for miles around leaving a black memory behind (Stanley, 1969).
The Gulf of Mexico oil spill has had an extremely negative effect on the surrounding wildlife and ecosystem. The oil spread across the gulf contaminating any living organism that came into direct or indirect contact with it. The oil cuts off the ability of oxygen from the air to move into the water which directly harms fish and other marine wildlife that require that oxygen. The dispersant that the BP is using to try and break up the oil moves the slick into the entire water column which contaminates the ocean floor which would most likely not have seen any damage if it wasn’t for the use of these dispersants. More than 400 species that live in the Gulf Islands and marshlands are at risk and as of November 2 s...

Although bioremediation can be used for many sources of contamination such as pesticides, gas sites, landfills and more, oil spills are a large source of pollution for our oceans. The environment is constantly being polluted by petroleum hydrocarbons due to tanker accidents, offshore drilling, pipeline leaks, and from cars whose oil gets washed down ocean drains when it rains (Margesin et al., 2007). In 1979 there was an offshore drilling spill in the Mexican coast releasing 400 thousand tons of oil. In 1989, the Exxon Valdez oil spill leaked over 14 thousand tons of oil into Alaskan waters (Swannell et al., 1996). In 1991, Iraq intentionally “spilled” over 14 million tons of crude oil into the Persian Gulf. In 2000, there was an oil spill from pipelines in Guanabara Bay releasing more than one thousand tons of oil. In November 2002, the Prestige sank to the bottom of the ocean after bre...
