Recent changes in plastic bottles washing ashore on Inaccessible Island, Tristan da Cunha

Plastic bottle litter on Inaccessible Island, part of the UNESCO-listed Gough and Inaccessible Islands, has doubled since 2018, with drink containers now constituting 90% of all washed-up debris. A striking shift toward smaller, predominantly Asian-produced bottles—now accounting for 88% of arrivals—has intensified marine pollution. Most bottles originate from China and are less than two years old upon arrival, indicating recent production and rapid dispersal. The study, published in Marine Pollution Bulletin, analyzed trends in bottle litter to assess the impact on this remote World Heritage Site.
