Huge volume of debris discovered on remote Pacific Island
Henderson Island, part of the UK’s overseas territory in the South Pacific, has been found to be littered with an estimated 37.
Henderson Island, part of the UK’s overseas territory in the South Pacific, has been found to be littered with an estimated 37.7 million pieces of plastic. Beaches around the island were thoroughly surveyed between the end of May and middle of August 2015 by researchers from the University of Tasmania and the RSPB. The researchers found up to 671 items of plastic for every square metre of beach surveyed. This huge density of litter is despite Henderson’s extremely remote position, and the fact that it is not inhabited by humans. However, it is close to the centre of the South Pacific Gyre, the circulatory ocean that carries huge volumes of floating litter on the sea’s surface. Dr Jennifer Lavers, lead researcher, said “Far from being the pristine ‘deserted island’ that people might imagine of such a remote place, Henderson Island is a shocking but typical example of how plastic debris is affecting the environment on a global scale.” “Based on our sampling at five sites we estimated that more than 17 tonnes of plastic debris has been deposited on the island, with more than 3,570 new pieces of litter washing up each day on one beach alone.” She added: “Plastic debris is an entanglement and ingestion hazard for many species, creates a physical barrier on beaches to animals such as sea turtles, and lowers the diversity of shoreline invertebrates. “Research has shown that more than 200 species are known to be at risk from eating plastic, and 55% of the world’s sea birds, including two species found on Henderson Island, are at risk from marine debris.” Dr Laura Foster, MCS Head of Pollution, says “This truly highlights the global problem of marine litter which is why, through our Beachwatch project, we not only encourage beach cleans to remove litter but we also ask our volunteers to survey what they find. This data can then be used on a local, national and global level to stop litter getting into our oceans and ending up in places like this.” Join a beach clean and survey Take the Plastic Challenge Laversa, JL & Bond AL (2017). “Exceptional and rapid accumulation of anthropogenic debris on one of the world’s most remote and pristine islands” PNAS www.pnas.org/cgi/doi/10.1073/pnas.1619818114

Did you know?…
It’s estimated that one rubbish truck load of plastic litter enters the ocean every minute
Over time, one plastic bottle bobbing along in the ocean can break down in to hundreds of tiny plastic pieces
Plastic has been found in the stomachs of almost all marine species including fish, birds, whales, dolphins, seals and turtles

To date, our beach clean volunteers have removed 6 million pieces of litter from our beaches and collected marine litter data to support our campaigns for cleaner seas and beaches.Learn more and join a beach clean
