Seven species of sea turtles face extinction threats including beach habitat loss, fishing bycatch, and plastic pollution, with individual turtles enduring significant suffering from human impacts.
Individual sea turtle welfare involves multiple human-caused threats. Entanglement in fishing gear causes drowning — a prolonged death as air-breathing animals struggle to surface. Plastic ingestion causes bowel obstruction and slow starvation. Beach lighting causes hatchlings to travel away from the ocean, dying of dehydration or predation. Fibropapillomatosis, a debilitating disease linked to pollution and degraded habitats, causes tumors on eyes and flippers. Each of these causes individual suffering at scale.
