Sea Turtle Light Pollution and Welfare

Artificial light pollution on nesting beaches disrupts sea turtle nesting and hatchling orientation causing significant welfare harm.

Key Facts

Sea turtle nesting females avoid beaches with high artificial light levels
Hatchlings orient toward the brightest horizon, normally the sea
Artificial lighting causes hatchlings to move toward roads causing mortality
Beach lighting ordinances significantly improve hatchling emergence success

Welfare Considerations

Nesting female sea turtles disrupted by artificial lighting abort nesting attempts wasting the energetic investment of migration. Hatchlings disoriented by artificial light crawl inland toward roads rather than the sea, dying from dehydration, exhaustion, or vehicle collision. Long-wavelength amber lighting is less disruptive to turtles than white light. Beach lighting ordinances during nesting season dramatically reduce these welfare harms.

What You Can Do

Support local beach lighting ordinances during turtle nesting season
Shield or eliminate artificial lighting visible from turtle nesting beaches
Use amber long-wavelength lighting as an alternative near nesting areas
Volunteer for turtle nest monitoring programs
