Researchers examined the diet and plastic ingestion of green sea turtles inhabiting waters around the Ogasawara Islands, Japan, and detected plastics in 7 of the 10 individuals studied. By integrating genetic, isotopic, and plastic analyses, they estimated that the ingested plastics originated from areas beyond the turtles' migratory range, indicating the influence of transboundary marine pollution. The paper is published in the journal PeerJ.
