It is no secret that the Hawaiian green turtle population is recovering. The International Union for Conservation of Nature Red List classified the population as “least concern” in 2012, and the 2015 Endangered Species Act global status review concluded that Hawaii’s population of approximately 4,000 nesting females per year was increasing at a rate of 5.4 percent annually.

Plastics threaten many forms of marine wildlife through ingestion, entanglement, and the degradation of habitats and ecosystems. Sea turtles are of particular concern because their complex life histories, highly mobile behaviors, and use of numerous marine habitats expose them to harm from plastic pollutants through many different pathways.

South America has nearly 90,000 miles of coastline, and five of the world’s seven sea turtle species call the Pacific, Atlantic, and Caribbean waters and the beaches of South America their home for at least part of their life cycles.

Where Cape Cod juts into the Atlantic Ocean from the east coast of the United States, it forms Cape Cod Bay and the southern end of Massachusetts Bay. The area, which bears the grim moniker “the Deadly Bucket,” is the site of the world’s largest recurring sea turtle stranding phenomenon.
