How doe's oil pollutes the environment?

Answer 1

Oil spills into the sea endanger marine life by poisoning and by clogging feathers and gills.They prevent sunlight from penetrating the water and reducing dissolved oxygen levels.They contaminate the surrounding beaches and harm many birds and other creatures.

The 1989 grounding of 'Exxon Valdez' in Prince William Sound,Alaska caused the USA's worst oil spill.Thousands of birds,fish,sea otters,seals and killer whales were killed.

Answer 2

Oil Spill Behavior and Effects

Spilled oil poses serious threats to fresh water and marine environments, affecting surface resources and a wide range of subsurface organisms that are linked in a complex food chain that includes human food resources. Spilled oil can harm the environment in several ways, including the physical damages that directly impact wildlife and their habitats (such as coating birds or mammals with a layer of oil), and the toxicity of the oil itself, which can poison exposed organisms. The severity of an oil spill's impact depends on a variety of factors, including the physical properties of the oil, whether petroleum-based oils or non petroleum-based oils, and the natural actions of the receiving waters on the oil.
