What Threats Are Sea Turtles Facing?
Sea turtles face several significant threats that impact their survival, including:
Habitat Destruction caused by coastal development, including construction, leads to the destruction of critical nesting beaches. Erosion, along with the loss of coral reefs and seagrass beds, further contributes to the loss of vital habitats for sea turtles.
Climate Change poses major risks through rising temperatures, sea levels, and ocean acidification. Higher sand temperatures at nesting sites can alter the sex ratios of hatchlings, as turtle sex is temperature-dependent during incubation. Additionally, climate change disrupts ocean currents, affecting sea turtle migration patterns and food availability.
Pollution, particularly plastic debris, severely threatens sea turtles. Ingesting plastic, often mistaken for food, can lead to internal injuries or death. Chemical pollutants, such as oil spills and pesticides, contaminate both their habitat and food sources.
Bycatch is another significant threat, as sea turtles are unintentionally caught in fishing gear like nets, longlines, and trawls. Bycatch can result in severe injuries or death due to drowning, as turtles must surface for air.
Illegal Trade and Poaching continue to threaten sea turtles, with their meat, shells, and eggs harvested for use in traditional medicine and as delicacies.
Light Pollution on beaches can disorient hatchlings, leading them away from the sea and into danger. Light pollution also discourages females from nesting, negatively impacting reproduction rates.
Predation of eggs and hatchlings by birds, crabs, raccoons, and dogs further endangers sea turtle populations, especially in their early stages of life.
Boat Strikes are a severe threat, as collisions with boats and ships often result in severe injuries or death, particularly in areas with heavy boat traffic.
