Wild Sea Turtle Artificial Light Disorientation

Artificial light pollution on nesting beaches disorients sea turtle hatchlings away from the ocean, causing mass mortality from exhaustion and predation.

Key Facts

Hatchlings orient toward the brightest horizon which is naturally the ocean
Beach development lights attract hatchlings inland where they die from heat and predation
Amber LED lights on a longer wavelength are less disorienting than white or blue lights
Even single bright lights visible from beaches can cause significant disorientation

Welfare Considerations

Artificial light disorientation causes mass hatchling mortality through exhaustion, dehydration, and predation as misdirected hatchlings wander inland. The suffering of disoriented hatchlings is real and preventable through lighting ordinance compliance. Each protected beach saves thousands of individual hatchlings annually.

What You Can Do

Support beach lighting ordinance compliance and enforcement
Replace visible beach lights with amber LEDs on turtle nesting beaches
Participate in hatchling disorientation response programs during nesting season
Advocate for dark sky ordinances in coastal development planning
