Oil that is spilled in the ocean water can kill. When oil is spilled, oil floats on the surface of water because oil will not mix with water. The oil expands and a thin layer called a slick on the surface of the water. Oil then expands more to become a layer, called a sheen that is 0.01 mm thick. Ecosystems can become imbalanced and animals could die and we could be affected because our food sources would slowly diminish. "Over the past 50 years, humans have changed natural ecosystems more rapidly and extensively than in any comparable period in human history," (Dr Lee) The amount of oil we can get by off shore drilling is not worth the cost if it means possible environmental damage.
Many animals are affected in different ways. Oil does serious damage to the bird’s feathers. The feathers are aligned in a certain way to keep the bird warm and waterproof. Birds apply natural oil on feathers to further keep them waterproof, which is called preening. When a bird comes into contact with crude oil, their feathers mat and separate which exposes the bird’s sensitive skin. Automatic...

- Drilling oil in Alaska's Arctic National Wildlife Refuge (ANWR) is a serious issue for environmentalists and for the future of the United States. Should the Arctic National Wildlife Refuge be opened to oil drilling. This paper will debate whether or not we should allow Arctic National Wildlife Refuge to be opened to oil drilling. This will also show the impact it has on the environment, and I will show a critical analysis of the current issue of whether or not to drill. History Arctic National Wildlife Refuge is located in the Northeastern part of Alaska and is the largest wildlife in the country.... [tags: Oil Drilling Environment]

- People in the U.S. use oil every day. Powering cars, heating homes, and providing electricity are just a few examples of how we use oil fuels in our daily life. Where would we be if we woke up tomorrow and couldn't fly because there was no fuel, or products containing plastic were taken off the market. "In fact, oil is a part of everyday items such as crayons, bubble gum, and deodorant (Mooney 19). Oil is the number one source of energy in the U.S. today. However, the U.S. imports 140 billion worth of its oil supply every day from unstable regions such as Canada and Mexico (news desk).... [tags: offshore drilling,petroleum extraction,carbon]

- In 1973, it was thought that there were potentially one-hundred billion barrels of oil lying in the Atlantic Ocean off the U.S. Coast. That may seem like a lot of oil, but the U.S. was estimated to consume 17.3 million barrels of oil a day at the time (Smith 232). After knowing that, the one-hundred billion barrels doesn’t seem like so much. Offshore oil drilling not only created a business, but also tapped into crucial resources for a booming American way of life. However, with great benefits come certain consequences....

- Negative Effects of Oil Drilling Issues facing the marine environment regarding oil pollution in water have always been a problem, but more recently it has been becoming more common. Because oil drilling harms the marine life, it raises the question: is oil drilling really the best idea. There is research out there that proves that marine oil spills are extremely harmful to both sea creatures, and the earth. There should be an alternative to oil drilling in the marine environment, due to potential marine oil spills that can occur and harm the many living creatures of the ocean....

- Oil drilling is an issue that needs more attention, attention to the destruction It is causing, attention to how it is impacting our environment. The accident in the gulf of Mexico should have opened up our eyes in how idiotic and dangerous oil drilling is that 's why we need to stop them. To narrow down where we should stop is Alaska. "In recent reports by the NRC ,confirms that oil drilling in the north slope of Alaska has had an environmental and economic effect in the last three decades." ("Save ANWR") and by continuing to take oil out of the ground there are now empty holes under ground, which means with one bad earthquake will cause a huge catastrophe in Alaska, making harder for anim...

- Crude oil is black gold that has been even sought out even in the ancient times. The Chinese in the fourth century drilled 800 feet deep oil wells to burn the oil to produce salt. Oil has a long history. America’s has massive oil demands and off-shore drilling has become a temporary solution and scientist are trying to find alternative sources of energy that can last us a very long time. There are many disadvantages and hazards when it comes to offshore drilling. Theses disadvantages can affect the wildlife, animal population, marine environments, pollution and much more....

- The existence of crude oil has been known for centuries, and throughout time the growing demand for the resource has driven the exploration, and production to its highest expansion. The Earths' natural reserve of crude oil is finite; it is not a renewable resource. Corn and Copeland stated that based on survey studies one-half of the remaining undiscovered crude oil and natural gas lie under the oceans and seas. According to the book "Public Reaction to Offshore Oil", the demand for crude oil is still increasing and there is no doubt, the resource is depleting and in the future, the world's production will be forced to start declining....
