Artificial light at night (ALAN) affects human health, wildlife, and economic sustainability. Reducing unnecessary ALAN can improve well-being, reduce energy costs, and protect wildlife and healthy ecosystems.
Artificial lighting poses a serious threat to sea turtles by disrupting critical nesting and hatchling behaviors. Bright coastal lights disorient nesting females and hatchlings, causing them to move inland instead of toward the ocean, which increases exhaustion, dehydration, and predation. Reducing ALAN at nesting beaches is essential to protecting critical nesting habitat, preserving natural orientation cues, and supporting the long-term survival of endangered sea turtles.
The Puerto Rico Lighting Retrofit Program, led by Urbanativa LLC, plays a key role in restoring natural darkness at nesting beaches while supporting compliance with local regulations.
