The overall ecological effects of light pollution are still poorly understood, but its consequences for sea turtles have been well-studied. The impact is twofold: newly hatched turtles are attracted to lights. Under natural conditions this attraction lures them into the sea, but where man-made lights outshine other sources, they are led inland, where they are likely to perish from exhaustion, dehydration, or predation. Light pollution also diminishes the attractiveness of nesting beaches. Where light fixtures have been installed adjacent to egg-laying sites, the females stop using them. While this severely limits the available number of suitable beaches, it also restricts the likelihood of eggs being deposited in spots that are perilous for young turtles
