Abstract: "Humanity is quickly crossing critical planetary boundaries that threaten sea turtle populations, their ecosystems and, ultimately, the “safe operating space” for human existence. Sea turtles have survived millions of years, but marathon migrations put them at increasing risk for the additive impacts of adverse anthropogenic activity on land and at sea, including impacts from biodiversity loss, climate change, ocean acidification, land-use change, pollution (especially plastics), and more. The synergistic effects of anthropogenic threats and the return on conservation interventions are largely unknown. But analysts understand that their efforts will need to focus on both nesting beaches and ocean migration routes, while acting on a host of adverse impacts across many of the nine known planetary boundaries. Avoiding extinction will require adaptation by turtles and people, and the evolution of new, innovative conservation practices. Key strategies: boosting populations to weather growing threats, rethinking how humanity fishes, studying turtle life cycles (especially at sea), safeguarding habitat, and deeply engaging local communities."
