Question

how does oil spill affect sea birds and marine life?

Answer 1

Oil destroys the insulating ability of fur-bearing mammals, such as sea otters, and the water repellency of a bird's feathers, thus exposing these creatures to the harsh elements. Without the ability to repel water and insulate from the cold water, birds and mammals will die from hypothermia.

Many birds and animals also ingest oil when they try to clean themselves, which can poison them.

Fish and shellfish may not be exposed immediately, but can come into contact with oil if it is mixed into the water column. When exposed to oil, adult fish may experience reduced growth, enlarged livers, changes in heart and respiration rates, fin erosion, and reproduction impairment. Oil also adversely affects eggs and larval survival.

Answer 2

Oil spills are very dangerous to sea birds and marine life. We can say this as oil spills damage the insulating ability of fur-bearing animals. Oil soils also block the passage of oxygen into the water as the oil makes a layer over the water thus blocking oxygen.
