Scientists say Henderson Island has more plastic waste than anywhere else in the world, but it's hoped a floating barrier could be the answer to cleaning it up.

The island's in the South Pacific Ocean and researchers think almost 38 million pieces of rubbish are on its beaches.

No-one lives there but it is home to wildlife.

It's hoped a new floating barrier that can separate out rubbish that gathers in the ocean will be able to help the island.
