Question

how does oil spill effects seabirds and marine life

Answer 1

oil spill affects the seabirds to destroy their life on being smoke and later the marine creatures fuel would have used as petroleum

Answer 2

O2 naturally dissolves in sea. But when oil spills on sea, O2 does not dissolve in the sea. This reduces O2 level in the sea. This also happens when we put kerosene on potholes to prevent the breeding and growth of mosquitoes.

Sometimes, sea birds get soaked in oil while catching fishes.

It affects fishes that stay near the surface. If they get soaked in oil, then their predators may die after eating them.
