Sea Turtle Light Pollution

Artificial light pollution on nesting beaches disorients sea turtle hatchlings and nesting females, contributing to population declines.

Key Facts

Hatchlings navigate to the ocean by following the brightest horizon
Artificial lights cause hatchlings to move inland where they die
Female turtles may abandon nesting attempts due to beachfront lighting
Seven of eight sea turtle species are threatened or endangered

Welfare Considerations

Light pollution causes significant mortality for sea turtle hatchlings who spend hours or days wandering inland before dying from dehydration or predation. This represents a preventable welfare and conservation crisis. Beach lighting ordinances during nesting season can dramatically reduce hatchling mortality.

What You Can Do

Support turtle-friendly lighting ordinances in coastal communities
Use red-spectrum lighting on beachfront properties during nesting season
Participate in hatchling disorientation rescue programs
Support beach monitoring programs during nesting season
