- Oil Spills: Oil spills can coat sea turtles’ feathers and skin, causing hypothermia and death.
- Chemical Pollution: Chemical pollutants, such as pesticides and industrial chemicals, can accumulate in sea turtles’ bodies and cause harm.
Hunting and Poaching
Sea turtles have been hunted for their meat, eggs, and shells for centuries, and this continues to be a major threat to their survival.
- Meat and Eggs: Sea turtles are hunted for their meat and eggs, which are considered a delicacy in some cultures.
- Shells: Sea turtles’ shells are highly valued for their beauty and durability, leading to their exploitation for decorative and commercial purposes.
- Traditional Medicine: Sea turtles are also hunted for their supposed medicinal properties, such as their shells and organs.
Disease and Parasites
Sea turtles are susceptible to various diseases and parasites, which can weaken their immune systems and lead to death.
- Fibropapillomatosis: This is a viral disease that causes tumors to grow on sea turtles’ skin and internal organs.
- Parasites: Sea turtles can be infected by various parasites, such as tapeworms and roundworms, which can cause harm and weaken their immune systems.
Other Threats
There are several other threats to sea turtles, including:
- Light Pollution: Artificial lighting can disrupt sea turtles’ nesting behavior and cause them to become disoriented.
- Noise Pollution: Noise from human activities, such as shipping and construction, can disrupt sea turtles’ behavior and communication.
- Invasive Species: Invasive species, such as rats and cats, can prey on sea turtles and their eggs.
What Can Be Done to Mitigate These Threats?
There are several ways to mitigate the threats to sea turtles, including:
