Marine Turtle Welfare: Multiple Threats

Marine turtles face welfare challenges from plastic ingestion, bycatch, temperature-dependent sex determination disruption, and nesting beach erosion.

Key Facts

Sea turtles have existed for 110 million years but all seven species are now threatened
Temperature-dependent sex determination means warming beaches produce predominantly female hatchlings
Plastic bag ingestion is documented in 52% of all sea turtle species
Artificial lighting on nesting beaches disoriates hatchlings causing them to move away from the sea

Welfare Considerations

Individual turtles suffering from plastic ingestion experience progressive starvation as the gut fills with indigestible material. Bycatch causes drowning. Beach erosion from development eliminates nesting habitat. Climate change disrupts sex ratios. The cumulative welfare impact on long-lived, slow-reproducing animals is especially significant because each loss of reproductive-age adults depletes populations that take decades to replace.

What You Can Do

Reduce single-use plastic consumption to decrease ocean plastic burden on marine turtles
Support sea turtle nesting beach monitoring and protection programs
Choose seafood certified to avoid turtle bycatch
Advocate for dark-sky ordinances near sea turtle nesting beaches to prevent hatchling disorientation
