Oil Spill in the Amazon and the Politics Behind it

- In 2007 30,000 farmers living on the banks of the Amazon in the Napo region in Ecuador sued Texaco-Chevron under the claims that they had polluted the Amazon River in which their livelihood is dependent on. The lawsuit followed a rupture an oil pipeline going through the Amazon, said to be caused by “natural causes” the rupture in the pipeline had resulted in 14,000 barrels of oil spilled. There has been 117 oil spills in Ecuador in the past 30 years, activist have claimed that the total amount of barrels spilled in the past 30 years has been greater than the amount spilled during the Exxon Valdez Disaster. This is a classic scenario of Oil fields and refineries dumping their waste in the very fragile ecosystems, the only difference is that people have found the courage to step up to big corporations and case may result in Texaco having to pay multi-million dollars to 30,000 farmers





The Effect of Oil on Animals
- To date is has been almost 20 years since the Exxon Valdez disaster has occurred in the Prince William Sound, but it has been reported that Otters and other sea animals are still suffering from the effects of the oil spill. Animal recovery when it comes to oil must be very swift for any chance of survival and is due to large amount of volunteers, but that still isn’t enough ,every year half a million birds die because of spilt oil. Due to the effort of various organizations the amounts of death in birds have decreased each year because of close monitoring once released. Humans are also affected by the death of animal, for example fishing villages in along the Prince William Sound have suffered heavily because of the spill. Fish have been contaminated and their eggs also become contaminated as result villages lose their livelihoodood and it could be very hard to recover from such a disaster. This goes to show that humans should be more caring about oil spills knowing that it could affect them too




The Problem with Burning Oil
- On April 20 2010 deepwater well owned by British Petroleum exploded killing 11 platform workers. This disaster makes Exxon Valdez look like nothing; the Oil slick can be seen from space. There have been many preventative efforts in containing the Oil Spill some immediate methods have been using regular oil booms to contain the oil in a specific area and burning the oil. Burning oil as part of the recovery of oil is the most frowned upon because it is heavily frowned upon by environmentalist because of the amount of gases it releases into the atmosphere. Oil also affects the flight of bird planning up above, another reason why dependency on oil is bad because even the recovery process is harmful to the environment.

Written Summary

Oil spills occur all the time, but they are not always the large oil spills that are on TV but most of them occur discreetly and sometime intentionally. Oil is an important resource which is extremely valuable to the global economy so the drilling of it is essential. Oil spills are not necessarily the ones in which you see ten thousands of barrels being released but a ruptured pipeline owned by a major oil corporation, to avoid these types of spills the world itself needs to develop other types of energy sources and be less dependent on oil because it is evident that it’s production carries too high a risk to the environment. The reasons are not exactly evident why oil spills are detrimental the nature but it’s not humans that are most affected by it but animals.. Oil is a very dense mixture made of various hydrocarbons and different types of compounds, when this mixture gets on animals fur such as otters it ruins the entire purpose which is insulating the body and causes the animal to get hypothermia. Birds are also heavily affected by oil too when oil gets on their plumage they fail to fly and start ingesting the oil at an attempt to rid themselves of it but just end of ruining their internal organs. Intervention must be very swift when helping rescue animals from oil spills or else they end up dead, people overlook the important of animals in our ecosystem, they forget where they get their food from and who keeps the nature cycle going. The reasons why humans should be worried is that if they do not step and do something about oil spills is that nature is already in a fragile condition and without the help animals humans will be in greater trouble. This is a very global problem because almost every country economy depends on the oil industry and each of these countries has different policies on oil, an oil spill in the Gulf of Mexico raises gas prices in Britain. They are some short term methods of preventing oil spills such as oil booms which help contain the area where the oil has spilt but the sometimes they have to rely on burning the oil which causes a great problems with environmentalist because it adds to the air pollution. It is evident that the Oil industry poses great risk to the environment and it’s essential for humans to realize this and make a good effort to stop using oil and start using different energy sources because all the problems that oil causes isn’t worth the convenience

FAQ's

How Oil Spills can be avoided?

- Environmentalists and various governments have always argued over offshore drilling in the past decade. In the US it is an extremely debated subject especially since recent events have given more proof to why it should be banned. But not all major oil spills are caused by drilling platforms leaking but from tankers grounding or sinking. The need for oil requires such a precious amenity to be transported but if countries look to other energy resources, the purchase of oil across foreign waters would not be necessary and we would not have to run the risk of major leakage of oil in fragile marine ecosystems.

What harm does the release of oil cause to the environment?
- Oil contains many different hydrocarbons and different compounds; this mixture makes oil an extremely dense product. This affects both animals and plants, an example of this is birds. Birds are always the most effected animals except for fish when it comes to oil spills, the oil sticks to their plumage and prevents them from taking off, their instincts tell them to ingest the oil but that leads to devastating effects on their internal organs and is the cause of death for the birds. Under the surface of water lies an entire ecosystem of plants, and they also require photosynthesis but the density of oil prevents any sun from accessing the plants and they die therefore affecting the food source for many fish

How is oil spills cleaned up?
- Various methods are used to clean up oil spills. One of the most preferred methods is using oil booms which absorb the oil, oil booms are comprised of sometimes regular nylon stockings filled with animal fur or hair many organizations are dedicated to gathering hair for oil spill cleanup. They are other methods of getting rid of oil in water, burning is one of them but it cause air pollution and is frowned upon by most environmentalists

How do they occur?
- Major Oil Spills are mostly caused by drilling platforms leaking or tankers grounding on reefs, some oil spills release 100,000 to 1.5 million tons of oil. The main problem is the oil spreading

Are all Oil spills accidental?
- The highly publicized Oil Spills are mostly the big accidental ones but the truth is that those oil spills account for only 5% of Oil Spills. Most oil spills are caused by municipal dumping or by industrial waste such as oil refineries or oil fields. In Ecuador 30,000 inhabitants from the Amazon sued Chevron because all the waste from their Oil Field was polluting their river

Are they any organizations against off shore drilling?
- After Exxon Valdez in 1989 many different charities and organizations sprung up against off shore drilling, and ever since it has been ongoing debate between congress and environmentalist. You can donate to Matters of Trust or different organizations but recently President Obama has created a commission on preventing Oil Spills

What are some major oil spills?
- The biggest amount of oil released by oil spill was in the Persian Gulf during the First Gulf War where it was said that the Iraqi’s released oil in an attempt to prevent the marines from landing, but Exxon Valdez incident in Alaska which does not even place in the top ten for the most amount of oil released had probably had the worst impact on the environment than any other spill



How many animals die from oil spills?
- It varies from spill to spill but one of the worst environmental disasters was the San Francisco Bay spill where 2,519 dead birds were found. It ranges from how dense is the animal population in that area

Are there any immediate methods of avoiding oil spills?
- To make sure that tankers do not ground or hit a reef they have two boats constantly attached to them to tug the boat in case of emergency, there is also a method called double hulling in which they reinforce the hull of a tanker which can prevent ships from getting damaged.

How long does it take to clean up?
- It all depends on the efficiency of the people responsible for cleaning up the spill, the spill in the Gulf of Mexico in 1980’s took over a year to entirely clean up. Most spills take a few months to recover from but even after that areas affected by it continue to have problems an example of this are Alaskan villages in which the oil spill ruined the fishing industry.

Why Deep Water Oil Spills do Their Damage Deep Down: This article talks about the effects of oil spills not on animals but on plants down in the ocean. It talks about how if hydrocarbons are released into the water, then the water is polluted. But the problem is that when the water reaches a certain depth in the ocean it becomes almost impossible to recover. This really is a wakeup call that If offshore drilling doesn’t stop and accidents like these keep on occurring, it can spin out beyond our control
