An uninhabited island in the South Pacific is littered with the highest density of plastic waste anywhere in the world, according to a study.

Henderson Island, part of the UK's Pitcairn Islands group, has an estimated 37.7 million pieces of debris on its beaches.

The island is near the centre of an ocean current, meaning it collects much rubbish from boats and South America.

The joint Australian and British study said the rubbish amounted to 671 items per square meter and a total of 17 tonnes.

"A lot of the items on Henderson Island are what we wrongly refer to as disposable or single-use," said Dr Jennifer Lavers from the University of Tasmania.

The study, published in the journal Proceedings of the National Academy of Sciences, described how remote islands act as a "sink" for the world's rubbish.

In addition to fishing items, Henderson Island was strewn with everyday things including toothbrushes, cigarette lighters and razors.

"Land crabs are making their homes inside bottle caps, containers and jars," Dr Lavers told the BBC. "At first it looks a little bit cute, but it's not. This plastic is old, it's sharp, it's brittle and toxic."

The condition of the island highlighted how plastic debris has affected the environment on a global scale, Dr Lavers said.

"Almost every island in the world and almost every species in the ocean is now being shown to be impacted one way or another by our waste," she said. "There's not really any one person or any one country that gets a free pass on this."

Actually, sometimes we can be more environmental-friendly, the earth we live is just only one. When we are having fun on the beach, why not take things can be reused instead of plastic products? We love drinking, just take a full of silicone collapsible water bottle of drink in it, after drink out the collapsible water bottle can be easily toke to home. Sometimes every little step could change our environment and it’s often the simplest actions but have the greatest impact.
