Sea Turtle Light Pollution and Nesting Welfare

Artificial light pollution disrupts sea turtle nesting and hatchling orientation, causing massive welfare harm. Lighting solutions exist that protect turtles without eliminating human coastal activities.

Key Facts

Hatchling sea turtles orient toward the brightest horizon, naturally the moonlit sea, but are disoriented by beachfront lighting
Disoriented hatchlings moving inland face dehydration, predation, and road mortality
Nesting females avoid brightly lit beaches, reducing breeding success and population recovery
Long-wavelength amber LEDs are largely invisible to sea turtles while providing human-visible lighting

Welfare Considerations

Light pollution causes enormous sea turtle welfare harm by disorienting hundreds of thousands of hatchlings annually on nesting beaches worldwide. The solution is well-established: turtle-safe amber wavelength lighting, downward-directed fixtures, and light reduction ordinances in coastal communities near nesting beaches. These interventions allow coastal human activity while dramatically reducing hatchling mortality.

What You Can Do

Replace white outdoor lighting with turtle-safe amber LEDs at coastal properties near nesting beaches
Support and comply with local light ordinances protecting sea turtle nesting beaches
Turn off unnecessary outdoor lights during sea turtle nesting and hatching season
Donate to sea turtle nesting beach monitoring and hatchling disorientation rescue programs
