Climate change is having a profound impact on green sea turtles. Some of the ways in which climate change affects sea turtles include:
- Sea level rise: Rising sea levels are causing erosion and flooding of coastal areas, leading to habitat loss and degradation.
- Temperature changes: Changes in temperature can affect the sex ratio of sea turtle hatchlings, with warmer temperatures producing more females.
- Changes in food availability: Climate change can affect the availability of food for sea turtles, leading to malnutrition and starvation.
It is estimated that up to 70% of sea turtle nesting sites will be lost due to sea level rise by 2050.
Hunting and Poaching
Hunting and poaching are significant threats to green sea turtles. Sea turtles have been hunted for their meat, eggs, and shells for centuries, and this continues to be a major threat to their survival. Some of the ways in which hunting and poaching occur include:
- Direct hunting: Sea turtles are hunted directly for their meat, eggs, and shells.
- Incidental hunting: Sea turtles are caught accidentally in fishing gear intended for other species.
- Poaching: Sea turtles are poached for their eggs, which are considered a delicacy in some cultures.
It is estimated that up to 30,000 sea turtles are hunted every year.
Disease
Disease is a significant threat to green sea turtles. Some of the diseases that affect sea turtles include:
- Fibropapillomatosis: A viral disease that causes tumors on the skin and internal organs of sea turtles.
- Herpesvirus: A viral disease that causes skin lesions and respiratory problems in sea turtles.
- Bacterial infections: Bacterial infections can cause a range of health problems in sea turtles, including pneumonia and septicemia.
It is estimated that up to 50% of sea turtles in some populations are affected by disease.
Conservation Efforts
Despite the many threats facing green sea turtles, there are many conservation efforts underway to protect and conserve these magnificent creatures. Some of the ways in which conservation efforts are being made include: (See Also: Can You Swim With Turtles In Maui)
