Seabed 'covered in human litter'

Large areas of the sea bed are covered with human litter such as plastic bags, bottles and discarded fishing nets, scientists have discovered.

Researchers looking at samples from all over the world found that plastic was the most common litter, accounting for 41% of the waste on the seabed.

Dr Kerry Howell from Plymouth University's Marine Institute said the study showed litter was present "in all marine habitats, from beaches to the most remote and deepest parts of the oceans".
