However, their numbers have been dwindling at an alarming rate, and it is essential that we understand the reasons behind their decline to take effective measures to protect them.
Overview
Green sea turtles (Chelonia mydas) are listed as endangered on the International Union for Conservation of Nature (IUCN) Red List, with their population having declined by more than 50% over the past few decades. The main objective of this article is to delve into the primary reasons contributing to the decline of green sea turtles, including habitat destruction, pollution, entanglement in fishing gear, climate change, and hunting. By exploring these factors, we can gain a deeper understanding of the complex issues surrounding the conservation of these incredible animals and work towards ensuring their survival for generations to come.
Understanding the Complexity of the Issue
The decline of green sea turtles is a multifaceted problem that requires a comprehensive approach to address. It is crucial to recognize that the fate of these turtles is inextricably linked to the health of our oceans and the planet as a whole. By examining the various threats faced by green sea turtles, we can develop effective strategies to mitigate their impact and create a safer, more sustainable environment for these incredible creatures.
Reasons Why Green Sea Turtles Are Endangered
Green sea turtles, scientifically known as Chelonia mydas, are one of the most iconic and beloved species in the world. However, these magnificent creatures are facing numerous threats that have led to their decline in population, earning them a spot on the endangered species list. In this article, we will delve into the reasons why green sea turtles are endangered and what can be done to protect them.
Habitat Destruction and Fragmentation
One of the primary reasons why green sea turtles are endangered is the destruction and fragmentation of their habitats. Sea turtles rely on specific habitats, such as coral reefs, seagrass beds, and mangrove forests, to survive. However, human activities such as coastal development, dredging, and pollution have led to the destruction of these habitats, leaving turtles with limited options for feeding, breeding, and nesting.
For example, coral reefs, which provide vital food sources for green sea turtles, are being destroyed at an alarming rate due to climate change, pollution, and overfishing. According to the National Oceanic and Atmospheric Administration (NOAA), coral reefs are being lost at a rate of 1% per year, which is equivalent to losing a football field of coral every 10 minutes.
Entanglement in Fishing Gear
Another significant threat to green sea turtles is entanglement in fishing gear. Sea turtles often get caught in fishing nets, lines, and other gear, which can cause injuries, drowning, and even death. According to the World Wildlife Fund (WWF), it is estimated that over 100,000 marine animals, including sea turtles, are caught in fishing gear every year.
Fishing gear, such as longlines and gillnets, can be particularly deadly for green sea turtles. Longlines, which are used to catch fish such as tuna and swordfish, can stretch for miles and have thousands of hooks that can catch turtles. Gillnets, on the other hand, are used to catch fish such as cod and haddock, but can also trap turtles.
Bycatch and Discarding
Bycatch, which refers to the catching of non-target species, is another significant threat to green sea turtles. When turtles are caught accidentally in fishing gear, they are often discarded back into the ocean, where they can suffer from injuries, drowning, or even being eaten by predators.

According to the Food and Agriculture Organization (FAO) of the United Nations, bycatch is a significant problem in the fishing industry, with an estimated 38 million tons of bycatch discarded every year. This not only harms sea turtles but also other marine species, including fish, birds, and mammals.
Climate Change
Climate change is having a profound impact on green sea turtles, particularly in terms of their nesting sites and food sources. Rising sea levels and increased storm frequency are eroding nesting sites, making it difficult for turtles to lay their eggs safely.
Additionally, climate change is altering the distribution and abundance of sea turtles’ food sources, such as jellyfish and seaweed. This can lead to malnutrition and starvation, particularly for juvenile turtles that rely on these food sources to survive.
Pollution
Pollution is another significant threat to green sea turtles, particularly in the form of plastic pollution. Plastic debris, such as bags, straws, and microbeads, can be ingested by turtles, causing blockages, nutrient deficiencies, and even death.
According to the Ocean Conservancy, it is estimated that over 8 million tons of plastic waste enter the ocean every year, with much of it ending up in the stomachs of marine animals, including sea turtles.
Hunting and Poaching
Hunting and poaching are still significant threats to green sea turtles, particularly in certain parts of the world. In some cultures, sea turtles are considered a delicacy, and their eggs, meat, and shells are highly valued.
According to the International Union for Conservation of Nature (IUCN), hunting and poaching are significant threats to green sea turtles, particularly in countries such as Indonesia, Malaysia, and the Philippines. (See Also: Do Turtles Like To Be Held)
Disease and Parasites
Disease and parasites are also affecting green sea turtle populations. Fibropapillomatosis, a tumor-causing disease, is particularly prevalent in green sea turtles, and can cause significant mortality.
Parasites, such as barnacles and leeches, can also weaken turtles, making them more susceptible to disease and predators.
Conservation Efforts
Fortunately, there are many conservation efforts underway to protect green sea turtles. Some of these efforts include:
- Protected areas: Establishing protected areas, such as marine reserves and national parks, can help reduce human impact on turtle habitats.
- Research and monitoring: Studying turtle behavior, habitat, and population dynamics can help inform conservation efforts.
- Education and outreach: Educating the public about the importance of turtle conservation can help reduce human impact and promote sustainable practices.
- Reduction of bycatch: Implementing bycatch reduction devices and promoting sustainable fishing practices can help reduce turtle mortality.
- Reduction of pollution: Reducing plastic pollution and promoting waste management can help reduce the impact of pollution on turtles.
- Collaboration and international cooperation: Collaborating with governments, organizations, and local communities can help coordinate conservation efforts and share best practices.
What Can You Do to Help?
There are many ways you can help protect green sea turtles. Some of these include:
- Reducing plastic use: Refusing single-use plastics, such as straws and bags, can help reduce pollution.
