CHENNAI, India — For nearly four decades, residents in southern India’s coastal city of Chennai have patrolled moonlit beaches at night trying to protect sea turtles and their hatchlings that for millennia have nested along these shores.
Hungry dogs, locals looking for a snack, and disorienting lights are among the hazards facing the olive ridley turtles and their eggs, which can take up to 60 days to hatch. Many turtles are caught offshore in fishing nets, which this year alone have killed hundreds of them in the area.
Nonetheless, local residents have collected and helped to protect more than 260,000 turtle eggs this year in Tamil Nadu state, whose capital is Chennai.
Patrollers scan the beaches looking for turtles nesting or small sand mounds that might indicate eggs are buried underneath. When they find a cache of eggs, they transport them to a protected area and rebury them at the same depth as they were initially found. This is crucial since temperatures affect what sex the turtles will be. Researchers say rising temperatures from human-caused planet warming are resulting in fewer male turtles being born.
