Oil Spill
A B S T R A C T
Oil spill pollution, a severe environmental problem which arouses in a marine environment or in the water bodies, has grown into an alarming scale with the increase in oil production and transportation. Causes are either accidental or due to operational failure. Henceforth, it is almost impossible for marine life not to be a victim of this vulnerable zone. Our planet has the largest oil reserves, occasionally it cracks and rarely causes a major accident. However, human interference causes a devastating damage to marine and ecosystem.
Introduction
Oil is marked as the most used non-renewable natural resource throughout the planet. Innovations in the automobile technology has increased the demand for hydrocarbons as its used for the source of heat and light. Development in the petrochemical industry boosted the oil supply throughout the world. Today we have miles and miles of wired petroleum pipelines and tons of crude oil on the go. The quantity of oil transported over the sea has enormously increased in volume with tankers from a capacity of 100,000 to 500,000 tons resulting in increased possibilities of spillage by accident. In the event of an accident, oil pollution will be encountered in the marine environment or in inland water.
Within the past years Oil spills have created enormous debates and unhealthy concerns for the ecosystem. On April 22nd , 2010 will be remembered as one of the darkest days in the history of oil and gas industry.
The oil spills results of shipping accidents play a significant role in increasing the pollution. For example, in the 3rd of April 2010 4 tonnes of oil was spilled into the water.
In fact, of the tens of millions of gallons of oil that enter North American oceans each year due to human activities, only 8 percent comes from tanker or oil pipeline spills, according to the 2003 book Oil in the Sea III (Transportation Research Board and National Research Council) by the U.S. National Research Council of the National Academy of Sciences, which is still considered the authority on oil-spill data (Geographic).” Oil ends up in oceans very frequently, and is extremely bad for both marine wildlife and the environment as a
The oil spill created long term problems for the living organisms that inhabit the Gulf of Mexico. The oil covered the feathers of birds, making them unable to float at the surface. The oil killed some of the deep sea coral as far as seven miles away from the site. Mammals ingested the oil, which resulted in some of the mammals having internal bleeding and ulcers. This has also lead to an increase in sea turtles stranding, sick dolphins, and a decrease in population of many marine animals. This disaster stuck during the breeding season for many species of wildlife. “The oil’s toxicity may have hit egg and larval organisms immediately”, which could have wiping out those age classes. Population dips and cascading food web has occurred due to
To begin, the Exxon Valdez Oil Spill was a man-made environmental disaster that occurred in 1989. On March 24, the Exxon Valdez oil tanker struck Bligh Reef and spilled 260,000 barrels of crude oil into the waters of Prince William Sound in Alaska (Piatt, Lensick, Butler, Kendziorek & Nysewander, 1990). Eventually, this oil spread across 30,000 km² of water, damaging ecosystems and marine life along the way (Piatt, 1990). Evidently, this oil spill is considered to be one of the most destructive man-made environmental disasters in history (Dimdam, 2013).
Offshore oil drilling is a controversial topic because when oil spills, it does extensive amounts of damage to the environment. Countries capable of mining oil in the ocean reap the economic benefits in addition to reducing their dependency on external oil. While it is uncontroversial that offshore drilling is a massive boon for those countries, the environmental consequences of a spill also affect the economic welfare of nearby residents. Oil contaminates animals through a process called biomagnification, where chemicals progressively become more detrimental to the animals the higher they are on the food chain. When oil spills into the ocean, it impairs the growth of native species and deteriorates the ecosystem. As a result, the livelihood of people in the tourist industry, fisherman, and shrimpers is crippled and may take decades to recover.
An estimated amount of 206 gallons were let loose in the water.This oil spill has made the records of being one of the largest oil spills that has ever occurred. It happened when an oil well approximately a mile below the surface.blew out. In addition, this caused an explosion on the BP Horizon rig that killed 11 people. Experts made many attempts to stop the oil flow but it took time to reach success. However, every minute passing by is a very crucial one. Within as little as one day 2.5 million gallons were released into the water. The well was capped on July15, 2010. Meaning that the oil leaked for a grand total of 85 days. Resulting in 572 miles of the Gulf Shore being covered in oil. Not to mention the hundreds of animals found and taken into care due to the oil spill. Of course long term effects won’t be able to be further approached until time passes and experts are able to have obtained enough data throughout the years. However, experts have concluded that the damage from this oil spill will not be completely over with until years to come. Still today clumps of oil are being found coming from the shore. The oil is not the only thing to worry about however. Chemicals still remain in the environment and therefore can still affect the nature and can result in a chemical reaction which may be harmful. If parts of the oil are not able to reach oxygen it can just be a big toxic reservoir damaging the environment waiting to cause trouble.The only way to remove things like this is mechanically which only further destroys the habitat. Al in all it is a lose lose
There are so many reasons why pollution in Oceans water are the worst in the world. Oil is a Natural resource that most people use, it is found on certain areas in the world such as the bottom of Oceans. Oils spills can be involved as the result of deliberate sabotage or illegal dumping. Depending on the location and the condition, they have several techniques can be used to clean up the oil spills. 37 million gallons of oils is spilled in the Oceans each year. Most consequences of water pollution is caused by mishandling of oil products Proper disposal and recycling of used oils can go along way to help to prevent oil pollution in the water. In conclusion oil spills are so dangerous animals and maybe peolpe could die of oil pollution in waters.
oil spill happened five years ago and nearly 5 barrels of oil was spilt into the Gulf of Mexico. The oil spill was caused from an explosion through the Deepwater Horizon drilling rig about 40 miles off the coast of Louisiana. The main effect from this oil spill was the losses of the animals. Causing many to almost go extinct. As a result from the oil spill the earth has had—losses from pollution, the cost, and the damage of people.
The fish herring population crashed for four years and other fish also declined too, but the link to the oil spill has remained controversial. The scientist new study findings published in the online and suggest that the delayed effects of the spill may have been
Oil spills are notorious environmental hazards. Spills are costly to clean up, and they impact hundreds of
Throughout history, humans have had many adverse effects on the ocean. However, in the past century, a new threat to the ocean has arisen. Oils spills are one of the most dangerous human effects on the ocean, partly because they’re so difficult to reverse after they’ve happened, and because many of the chemicals that get released into the water are extremely toxic to a lot of creatures. Oil spills are usually caused by two ships colliding with each other, a ship colliding with another object, or as in the case of the BP oil spill, an explosion.
Understanding how oil spills often happen makes it easy to see that not only are they messy and dangerous, they are also inevitable. They can be lessened though. For years we have been told that drilling for oil was safe and that the chances of a catastrophic oil spill happening was too small to worry about. This was
For instance, Rufe, who is a scientist, states that we have not developed an approach that can clean more than 3 to 5 percent of the spilled oil” (Mufson, 2012). Furthermore, In the Gulf of Mexico, although 205.8 million gallons of oil have been spilled, just 51.8 million gallons have been collected, which equals approximately 25 percent. Moreover, in order to clean the Gulf from the oil spills almost 2 million gallons of toxic dispersants were used. Unfortunately, the toxic dispersants did not truly purify the spilled oil, but fractured them into tinier particles. As a consequence, that may make the oil more harmful for some ocean animals and plants ( A Center for Biological Diversity Report, 2008). However, with the increasing of offshore oil drilling accidents, and with no solution to solve the problem efficiently. The hazardous impact is not going to affect only on animals and plants. It might affect people who depend on the polluted area for food, ecological enrichment, and entertainment ( A Center for Biological Diversity Report,
Over 8000 animals were reported dead 6 months after the spill, including many that were on the endangered species list (7). Subsequently, seafood prices increased affecting restaurants and supermarkets. People abstained from going to beaches covered in oil, water sports and other aquatic attractions which meant that all organisations involved in tourism such as hotels, tour operators, restaurants and boat rental companies were affected (1). Furthermore, the method of cleaning up the oil by “in-situ burning” (burning oil in a contained area on the surface of the water), had adverse effects on the environment as the burning off of the oil led to mutations and increased mortality due to pollution.
Oil spills can impact the environment greatly. Since the oil boats are on the ocean if the break and start to leak it goes into the ocean where it can harm the ocean and those that make their home in it. “That spill caused an immediate and significant impact to the ecosystem, with sightings of birds and turtles washed up on beaches covered with oil, as well as an increase in the deaths of other marine life” (Sinclair, 2017). The oil spill in 2010 in the Gulf of Mexico was the biggest since Deepwater Horizon. It caused harm to the ecosystem around it because technology came in so it could pump oil out of the ground under the ocean. There is no way to know the impact that oil spill and really every oil spill has had on the marine ecosystem.
