How many animals are killed by oil spills each year?
Each year over 500,000 birds die worldwide due to oil spills. The recent BP oil rig disaster or the coast of Louisiana is a major ecological disaster, and the effects have been devastating.
How do oil spills affect wetlands and animals?
Oil coating coastal marshes and other wetlands contaminated sediments, poisoned wildlife and smothered salt-marsh grasses and other wetland vegetation. The death of vegetation in wetlands could result in significant erosion and habitat loss.
How many animals are killed by oil spills?
As many as 25,900 marine mammals may have been harmed by the spill. At least four species of marine mammals have been killed by the oil spill, including bottlenose dolphins, spinner dolphins, melon-headed whales and sperm whales.

The animals then receive another medical examination and are banded or tagged before released back into a clean habitat.
How do oil spills affect fish?
The negative effects on marine life relate to the accumulation of persistent and bioaccumulative components of oil in the tissue and bodies of marine life (fish) with the potential to induce a variety of health and reproductive problems, as well as mass mortality events within marine life in general.
How do oil spills harm the environment?
When oils rigs or machinery malfunction or break, thousands of tons of oil can seep into the environment. Oil spill effects on environments and habitats can be catastrophic: they can kill plants and animals, disturb salinity/pH levels, pollute air/water and more.
What happens when oil accumulates on the skin of animals?
Hair/Fur and Skin
Different classes of marine mammals experience different consequences from external oiling. ... When exposed to oil, the alignment of the hairs is altered, and the air layer is destroyed. Cold seawater is able to seep through the contaminated fur and causes the animal to rapidly become hypothermic.
How are turtles affected by oil spills?
When sea turtles surface in a slick, they can inhale oil and its vapors into their lungs; gulp oil into their mouths, down their throats, and into their digestive tracts while feeding; and become coated in oil, to the point of becoming entirely mired and unable to swim.

How oil spill affect marine flora and fauna?
Often, toxic oil constituents can also damage the reproductive organs of marine organisms: an increase in the number of sterile shellfish, for example, was observed during the year following an oil spill. In the case of corals, scientists reported that the number of progeny decreases in chronically oil-polluted areas.
How many fish are killed by oil spills?
Studies have determined that oil is particularly toxic for many species of larval fish, causing deformation and death. The federal study estimates that the disaster directly killed between two and five million larval fish.
How do oil spills affect invertebrates?
The paper notes that very low concentrations of oil can produce dramatic changes in invertebrate populations. ... Oil, not to mention the more toxic dispersants being used in the clean-up, can have a wide range of harmful effects, including changes to reproduction, growth, feeding, movement, behavior, and breathing.
How are oil spills caused?
Oil spills that happen in rivers, bays and the ocean most often are caused by accidents involving tankers, barges, pipelines, refineries, drilling rigs and storage facilities, but also occur from recreational boats and in marinas. Spills can be caused by: people making mistakes or being careless. equipment breaking ...
What happens after an oil spill?
