These islands are protected under international law, which protects them from illegal fishing and pollution.
However, this hasn't protected the island from masses of debris reaching their shorelines.
Upwards of 40 million items of plastic and rubbish have been washed ashore on the uninhabited Henderson Island, a UNESCO World Heritage Site which is about the size of Oxford; the ocean deposits up to 270 objects on its beaches every day.
Henderson lies in the middle of the South Pacific and is part of the Pitcairn Island Group, the only British Overseas Territories in this ocean.
Pitcairn is the only one of the four where human life can be found with a population of 52 people, mostly of who descended from the mutineers who took charge of the Bounty and scuttled the ship here in 1790.
