There are multiple ways in which oil spills can be cleaned in a safe and cost efficient way. Oysters in many areas of the gulf are returning. The BP oil slick had spread over 580 square miles in just three days. Factors such as oil-biodegradation, ocean currents and response measures (dispersants, burning) reduced coastal oiling. According to Nelson, (1999) pollution is said to occur when there is a release into the environment of substances and energy in quantities which are detrimental to man and other living organisms. As late as 2013, Cat Island, an important bird rooker… Because oil floats on top of water, less light penetrates into the water, limiting the photosynthesis of marine plants and phytoplankton. Since most of the oil floats in water, the sunlight absorbing capacity of the water decreases.

Examples of impacts to species included: up to 20 percent of all oceanic juvenile Kemp's Ridley sea turtles present during the Deepwater Horizon oil spill perished from oil exposure; and oil-associated health effects to Barataria Bay, Louisiana, bottlenosed dolphins reduced their survival and reproductive success in years following the spill, leading to a 50 percent decline in the population, according to … Aquatic beings cannot thrive in toxic environment and that makes oil pollution a disservice to them. The impacts of oil pollution on marine ecosystem can be categorized into long term and short term effects. One way is bioremediation, which is the use of microorganisms to break down pollutants.
