Red sea turtles have been listed as endangered species since 1986. Their numbers dropped sharply due to multiple factors. Unlike some land animals, they aren’t hunted for meat on a large scale, though there are still occasional illegal hunting incidents for their shells, which are mistakenly believed to have medicinal properties. However, plastic pollution poses a severe threat — turtles often mistake plastic bags for jellyfish, their main food. Once swallowed, the plastic can block their digestive systems, leading to slow and painful deaths. Additionally, beach development destroys their nesting grounds. Hotels and resorts built right along the shoreline take up the prime nesting areas, leaving the turtles with fewer safe spots to lay their eggs. Bright lights from these establishments cause baby turtles to crawl toward roads instead of the sea, where they often get hit by cars.
By 2000, fewer than 500 nesting females were recorded annually. To change this trend, conservation groups started relocating eggs to protected hatcheries. Volunteers guard beaches to stop poachers from stealing eggs. They also work with local hotels to dim lights during nesting season. By 2024, the number of nesting females had risen to over 1,200.
“People think sea turtles only matter for the ecosystem, but they’re important for local communities too,” says tourism officer Mike. “Guided turtle-watching tours bring in visitors. Kids love learning about them in our marine centers. Last year, over 10,000 people attended our turtle conservation workshops.”
