Offshore drilling regulation and the environmental impact of the Deepwater Horizon spill

¶ … Gulf oil spill [...] whether the United States should continue to pursue offshore drilling. Offshore drilling made the headlines when the British Petroleum (BP) drilling rig Deepwater Horizon exploded on April 20, 2010. Offshore drilling is necessary to augment our dependence on foreign oil, at least until we bring our usage of oil down, but the United States and other nations must develop far greater scrutiny if the practice is to continue. Currently, there are not enough controls and regulations on offshore drilling, and that needs to change drastically.

The definition of offshore drilling is any drilling for oil in the ocean at any depth. Offshore oilrigs used to be limited to near the coastline, but technology now allows them to drill much deeper, as the BP Gulf oil spill shows (Falola & Genova, 2005, p. 9). That rig is over a mile deep, and the only way to work on it is through robots, it is far too deep for divers to reach, which is one of the many problems facing BP as they attempt to bring the oil gushing out of the destroyed rig under control.

Offshore oil drilling has been going on for decades, and it has spread around the world as technologies have improved. Until 2008 the United States banned the practice, and Congress upheld that ban every year ("Green groups bolster lobby," 2008, p. A06). However, when oil and gas prices began to skyrocket, Congress lifted the ban. In October 2009, after BP filed numerous environmental impact and other documents with the government, drilling began. On April 20, 2010, the drilling rig Deepwater Horizon exploded, killing 11 workers and triggering the worst oil spill in American history. While BP reports they have finally tentatively capped the leak after 80+ days of oil leakage, the effects to the Gulf Coast area will be long lasting and devastating for many of the area's residents, including wildlife.

Impacts on biodiversity

Most people understand the grave danger the Gulf oil spill implies to the surrounding coastline. Two authors write, "While one small oil spill may not alter the landscape and wipe out entire species of animals permanently, several oil spills, blowouts, and pollutant emissions into the air within one region or body of water can" (Falola & Genova, 2005, p. 105). Clearly, this is not "one small oil spill." It is the most massive spill the country has ever experienced, far greater than the Exxon Valdez spill in 1989. Another group of authors note, "On March 24, 1989, the oil tanker Exxon Valdez hit a reef and spilled more than 11 million gallons of oil into Prince William Sound, a major fishing area in Alaska for salmon, shrimp, roe herring, herring roe on kelp, and other seafood" (Owen, Argue, Furchtgott-Roth, Hurdle & Mosteller, 1995, p. 4). Up until the Gulf spill, the Exxon Valdez spill was the largest in American history, and it clearly indicated the impact on biodiversity in Prince William Sound. Twenty-one years after the spill occurred in Alaska, there are lingering effects.

The Alaskan government created the Exxon Valdez Oil Spill Trustee Council to study the effects of the oil spill and monitor restoration procedures. They are funded through a civil settlement with Exxon. In 2009, they issued a 20-year report about the lingering effects of the spill on Prince William Sound and the ecosystem there. They found that there is "lingering oil" throughout the region impacted by the oil spill. This oil is underneath the seabed and beaches, and can be found when digging down into the soil in at least 50 areas along the sound. Wildlife was adversely affected in many areas, from fish to birds and sea otters, and in most cases, the populations of these animals dropped dramatically after the spill. The twenty-year study indicates that for most wildlife, their numbers have not returned to pre-spill populations, but they are on the increase. However, many different species continue to show the effects of the spill even today, including killer whales, Pacific herring, and pigeon guillemots are not recovering. Herring fishing was a major source of income for many anglers, and this industry continues to suffer as a result (Michel, and Esler, 2009).

What this indicates for the Gulf coast is quite clear. The billions of gallons of oil spilled in the Gulf incident is much more massive compared to the Exxon Valdez incident, and effects of that spill are still being felt in Alaska today. It ruined the livelihoods of thousands of fishermen and women, and changed the ecosystem for decades. The Gulf coast supplies a majority of the fresh seafood, such as oysters and shrimp that the country eats, and there is no estimate of how long these fisheries will be affected. It will certainly result in higher seafood prices around the country, but it will result in even more economic effects on the Gulf coast, that suffered dramatically after Hurricane Katrina hit in 2005. One has to wonder if the region can ever return to pre-Katrina standards after this additional blow to its ecosystem and economy.

Impacts on water quality

Clearly, such a large spill will have a dramatic impact on the Gulf's water quality. The spill is so massive it can be seen from space; satellites show it lingering off the coast of the Gulf coast communities. The oil will have a devastating effect on water quality and the Gulf ecosystem, but there are other factors that are affecting the water quality, as well. That is the dispersants and other chemicals that BP is using to help break up the oil. The EPA is monitoring these chemicals in the water, and it shows they are affecting water quality, as well. One university Web site maintains that oil is essentially biodegradable. They state, "Crude oil is an organic substance and, as such, is largely biodegradable. Given enough time, ocean turbulence will reduce an oil slick from a large cohesive film to separate droplets" (Editors, 2010). This may be true is small cases, but as the Exxon Valdez incident indicates, large amounts of oil take decades to biodegrade, and that will affect water quality and wildlife for decades to come. In addition, the dispersants are turning the oil into tar balls and sludge that is washing up on beaches, which makes it more difficult to clean up and further degrades the water quality.

Future policy formation on other energy sources

The Gulf spill has helped to change public opinion on oil and its production, and on how it is regulated. It seems much clearer after the spill that we are a nation far too dependent on foreign and domestic oil. The rise in gas prices last year helped show that, too. Oil is a non-renewable, dirty fuel, and Americans are the most heavily dependent on it. We need to form policies today that will positively affect our country and our ancestors in the next decades. The White House and Congress are attempting to pass laws on renewable energy that will benefit us all, but there is stiff opposition from lobbyists and many Republicans. While the administration did manage to get a bit tougher fuel-efficiency regulations through Congress, any sweeping changes in renewable energy have not passed. Lawmakers need to recognize that it is vital for the country to develop alternative sources of energy, not only to help the environment, but also to stop our dependence on non-renewable oil.

Creating alternative power sources, such as geothermal, wind, solar, and hydroelectric. Today, we are dependent on oil and coal, two of the dirtiest, most polluting power producers. Replacing old coal-fired electric plants with solar, wind, or geothermal plants is expensive, but it makes much more sense in the end. Over time, these alternative power plants pay for themselves, and they are far cleaner and less polluting than traditional plants. In addition, they use types of power that is renewable and good for the planet. The Gulf oil spill shows just how dangerous oil is, and how important it is to step away from non-renewable fuels in favor of more environmentally friendly alternatives.

Short- and long-term socio-economic consequences of oil spills and continued reliance on oil

The socio-economic consequences of the Gulf oil spill have yet to be analyzed. In the short run, experts already know that tourism has dropped dramatically, and reports indicate that many communities that are heavily reliant on tourism are collapsing all along the coast. With tourism down, the economic cost to these communities will be great, and if people continue to think the area is polluted after the spill is controlled, the area could suffer for years. The Exxon Valdez incident shows that communities suffer lengthy comebacks, and that some fishermen and others are still affected from the 1989 spill today. The same will certainly hold true for the Gulf coast, it is sad to say.

The economic affect on the fishing industry is still being assessed, as well. Oysters and shrimp are already affected, and many fishermen are worried about spawning areas for other fish and shellfish, which could also affect populations for years or decades to come. Most reports say it is really too early to assess the long-term effects to the residents, workers, and wildlife in the area, but prior studies indicate all of these things will be greatly affected. BP will have to pay damages, but that does not really make up for the long-term affects the region will suffer.

The economies and livelihoods of the region will certainly be impacted, but the biggest tragedy in the oil spill is that it happened, it has been so difficult to control, and that it is affecting so much wildlife. The Louisiana government says that 2,986 birds have been collected within the five states impacted by the spill, and of those, only 461 have been successfully released back into the wild (Editor, 2010). Sea turtles and dolphins have also been affected, and there are no estimates of how many fish and underwater plants are affected. Fisheries are closed, and the region is yet to feel the full brunt of the oil spill.

In conclusion, the Gulf oil spill is one of the worst natural disasters the nation has ever faced. The most important thing is getting the region cleaned up after the spill is contained. However, past experience indicates that the Gulf is going to suffer for a long time, and that it will take decades for species to come back to pre-spill numbers. The public will eventually forget the spill, and life will turn back to "normal." However, the spill really shows how shortsighted our energy policies are, and why we need to rely on renewable energy instead of oil. The country should continue offshore drilling in the future, but with much more stringent regulations and policies. They should have much more stringent disaster plans, as well. BP may not have thought a tragedy like this could occur, but it did, and there have to be ways to stop it from happening again.
