Doesn’t everyone love swimming in the ocean and seeing all the pretty sea life? Some people do, and when people are offshore drilling they can cause a lot of problems if something goes wrong. The biggest concern by environmentalist is not a spill, but the pollution of the air and water, damage to the ocean bottom and debris that washes ashore from day-to-day operations of oil and gas rigs. Oil Drilling can lead to jobs being endangered, animals dying, and damaging the eco system. So many animals are dying because of the oil in the water. Proofread to- Government wildlife experts have found just in Alaska that the BP oil spill has threatened more than 400 species including 34,000 birds, 656 sea turtles and 12 dolphins, and this count was taken the first couple days of the spill. The oil is still on a continuous flow. During this lifetime, we will not know the amount of damage and problems caused by the continuing oil spill in the Gulf of Mexico. The Deepwater Horizon oil spill was a massive ongoing oil spill and oil gusher in the Gulf of Mexico that started on April 20, 2010. The spill followed a blowout that caused an explosion on the Deepwater Horizon offshore drilling rig, which then sank off the coast of Louisiana (Barclay).   Tragically, eleven rig workers were missing and presumed dead; Thousands of barrels of oil per day had been gushing from a seabed well since the drilling rig exploded (Barclay). (Todd M. Schoenberger, Managing Editor, Taipan's Tipping Point Alert). Many were found without visible signs of oil exposure, and further tests are necessary to determine if oil was a culprit, said Dr. Michael Ziccardi, a professor at the University of California at Davis who heads the Oiled Wildlife Care Network.

Whenever oil is recovered from the ocean, other chemicals and toxic substances come up too; things like mercury, lead and arsenic that are often released back into the ocean. If all these chemicals are in the ocean, no one should be near that water because it can danger us greatly. So many jobs are being lost or cut off because of the oil spill; it’s making business market go down for a lot because they cannot get the supplies they need that come from the ocean. Oil drilling is damaging the eco system in many ways by killing plants, reefs, and so much more.

Offshore oil drilling is killing off so much of our sea life. Spills pose direct mortality dangers to birds through oiling and poisoning by ingestion as animals try to clean themselves and as toxins build up in fish-eating birds. In addition, over 200,000 birds die annually in collisions with oil and gas platforms. Construction of new pipelines will damage sensitive coastal habitats and marshes. The marine ecosystem is a highly complex environment and natural fluctuations in species abundance and distribution are a feature of the normal way it functions. These fluctuations can be large and difficult to relate to particular causes, as well as difficult to measure adequately. Against this background it is inevitably difficult to establish the precise extent and likely duration of environmental damage caused by an oil spill and to distinguish such impacts from changes brought about by a variety of other factors, both natural (e.g. climatic or hydrographic changes) and man-made (e.g. commercial fishing or other industrial pollution). Despite the scientific evidence that is available to the contrary, there is frequently a basic presumption that damage must have been caused by an oil spill, and terms such as "injury", "harm", "loss" and "impairment" are used without reference to any defined meaning or reliable evidence of a causal link.

Surveys have been done on marine mammals during oil and gas exploration that can cause temporary or permanent hearing loss, induce behavioral changes, and even physically injure marine mammals such as whales, seals and dolphins. Construction noise from new facilities and pipelines is also likely to interfere with foraging and...
