Oil spill effects not only humans ,birds mammals suffer from the effects of an oil spill. Even small spills can severely affect marine SEA WORLD.
There are many different types of oil and this means that each oil spill is different depending on the type of oil spilt. Each oil spill will have a different impact on Human life and Sea Creatures The place of the spill,the Creatures of wildlife in the area, seasonal migrations creatures,
Oil affects animals and birds by coating their bodies with a thick layer.Birds and mammals will not necessarily avoid an oil spill. Some marine mammals, such as seals and dolphins, have been seen swimming and feeding in or near an oil spill. Some fish are attracted to oil because it looks like floating food. This endangers sea birds, which are attracted to schools of fish and may dive through oil slicks to get to the fish.birds become easy prey, as their feathers being matted by oil make them less able to fly away; marine mammals such as fur seals become easy prey if oil sticks their flippers to their bodies, making it hard for them to escape predators;oiled feathers weigh more and their sticky feathers cannot trap enough air between them to keep them buoyant; birds bodies, for example by causing ulcers or bleeding in their stomachs if they ingest the oil by accident.
Oil does not have to be sticky wildlife. Both sticky oils such as crude oil and bunker fuels, and non-sticky oils Oils such as refined petroleum products do not last as long in the marine environment as crude or bunker fuel. They are not likely to stick to a bird or animal, but they are much more poisonous than crude oil or bunker fuel. While some of the following effects on sea birds, they are more commonly caused by Oil.

The U.S., U.K., Brazil, Mexico, Canada and Norway are likely to establish permanent spill response centers, requiring oil companies to pay for stockpiling materials needed to minimize damages. The U.S. has a program in place, funded by refiners, but it only pays out if the government can’t decide who’s responsible for a spill, or rules that an involved company is blameless.
Oil spills make up about 12% of the oil that enters the ocean. The rest come from shipping travel, drains and dumping.An oil spill from a tanker is a severe problem because there is such a huge quantity of oil being spilt into one place.Oil spills cause a very localised problem but can be catastrophic to local marine wildlife such as fish, birds and sea otters cannot dissolve in water and forms a thick sludge in the water. This suffocates fish, gets caught in the feathers of marine birds stopping them from flying and blocks light from photosynthetic aquatic plants.
More draconian measures will get an airing, but they’re unlikely to be adopted. For example, the government won’t require U.S. oil companies to drill an emergency relief well alongside each new well in water 1,000 feet or deeper.
The continental shelf of the Gulf of Mexico is also distinctive for intense seepage of natural liquid and gaseous hydrocarbons. Some authors believe that this can lead to formation of oil slicks and tar balls on the sea surface, which makes assessing and identifying anthropogenic oil pollution more difficult. In any case, the input of oil hydrocarbons from natural sources into the Gulf of Mexico is larger than in many other areas.
In the Baltic Sea, the Sea of Asov, and the Black Sea, the leading role in oil input most likely belongs to land-based sources, which are dominated by river inflow. The Danube River alone annually brings to the Black Sea about 50,000 tons of oil, half of the total oil input of about 100,000 tons
Traditional shipping and oil transportation routes are more exposed to the impacts of oil-polluted discharges from tankers and other vessels than other areas. For example, observations in the Caribbean basin [Atwood et al., 1987; Jones, Bacon, 1990; Corbin, 1993], where annually up to 1 million tons of oil enter the marine environment, showed that about 50% of this amount came from tankers and other ships [Hinrichsen, 1990]. In the Bay of Bengal and the Arabian Sea, oil pollution inputs from tanker and other ship discharges equal, respectively, 400,000 tons and 5 million tons of oil a year The most intense tanker traffic exists in the Atlantic Ocean and its seas, which accounts for 38% of international maritime oil transportation. In the Indian and Pacific Oceans, this portion is, respectively, 34% and 28% .
a feather up in the air and talk about a bird that is flying in the sky over the ocean, looking for something to eat. Then when it sees something to eat, swoop the feather down and dip it in a clear cup of water to show the bird diving down into the ocean. Pull the feather back out of the water. It will be wet, but the water will bead up and drip off, and if you give the feather a quick shake, it will be almost as good as new. Pass it around for the students to see.
Now take a cup of oil and talk about the same bird looking for something to eat. Use a different but identical feather so that you can compare it to the previous feather afterwards. Dip the feather into the oil this time. When you pull it out, the feather will be completely sopping and stick thin. Try shaking it off or drying it on a paper towel--it doesn't help. Have the students compare the two feathers and ask whether they think the birds would be able to fly. (If you have extra time, you can have the students Then, see if you can ask the students what the bird could do to get the oil off, and get the students to suggest washing the oil off by dipping it back in water. Of course doing this doesn't help, the feather stays smooched and unable to allow the bird to fly or keep the bird warm. Have the students talk raise their hands to talk about what this means for birds. Ask the students what they can do to help reduce oil pollution.
