Why Sea Turtles Matter More Than You Think

Sea turtles have been around for over 100 million years and outlived the dinosaurs and evolved with the changes in sea water. In the present day, the sea-going dragons and their extended descendants were on the verge of the worst ever conditions, not of nature, but of human activities. It matters not only to save a single species but the health of our oceans – and all the different varieties of life that inhabit them.

People often think of turtles sunning themselves on a beautiful beach or paddling about in the serene waters of a pond. They really are beautiful, but they're also important for reasons other than their looks. These are amazing animals that help to maintain biodiversity, ecosystem engineering, and are ocean health monitors.

When we know what an important role it plays in the life of the sea turtle, then we will understand the importance of safeguarding the planet's future.

Sea Turtles Matter More Than You Think

The Ancient Guardians of Our Oceans

Sea turtles have lived in the Earth's oceans for more than 100 million years. Currently, there are seven living species, with each having a unique role in the maintenance of marine ecosystems. Whether on tropical coral reefs or in open oceans and sandy beaches, they play a vital part in maintaining the habitats that many marine animals depend upon.

Sea turtles are considered to be a keystone species by scientists. As such, they can have a direct influence on the health of numerous other plants and animals. Conservation of turtles is a key conservation goal because the decrease in turtle populations results in imbalances in whole ecosystems. 

Healthy Sea Turtles Mean Healthy Oceans

Sea turtles are important because they are a key player in healthy marine ecosystems.

The corals form small patches of seagrass and regularly consume them to prevent the seagrass from growing over them. Sustainable seagrass habitats help to protect fish, sequester carbon, capture sediments and enhance water quality.

Hawksbill turtles consume sponges, which are competitors of corals for space. They maintain the balance of the sponge population and ensure a rich diversity of species on coral reefs—including thousands of marine species.

The leatherback turtle feeds on a large quantity of jellyfish, which helps in balancing the food web in the ocean. Leatherbacks are no longer considered a species with which to be afraid, and jellyfish can flourish in the absence of these big predators, causing fisheries disruption.

In short, healthy sea turtles contribute to healthier oceans—and healthier oceans benefit everyone.

Understanding Sea Turtles' Habitat

Protecting sea turtles' habitat is just as important as protecting the animals themselves.

Different species depend on a variety of habitats throughout their lives:

• Sandy beaches for nesting

• Coral reefs for feeding

• Seagrass beds for grazing

• Coastal lagoons for juvenile development

• Open oceans for migration

  
  

Coastal development, pollution and climate change have led to a decline in the habitat areas of many species of sea turtle. Disturbances from man-made lighting near beaches can confuse nesting females and hatchlings, and rising sea levels will lead to nest loss, if erosion does not do so already.

By providing suitable habitat protection, turtles can complete their remarkable life cycle, and many will return to the same very beaches where they had been born some years back.

Why Are Sea Turtles Endangered?

One of the most common questions people ask is, why are sea turtles endangered?

Virtually, all human actions constitute the solution.

One major cause of mortality is incidental catch (bycatch), which includes thousands of turtles caught annually. Plastic pollution is the other significant issue, as floating bags can resemble jellyfish and are one of the favourite food items of leatherback turtles.

Sea turtles are endangered

Illegal egg collection, meat and shell harvesting (including collection of "wild edibles") still occurs in some locations, and overdevelopment of the coastline is still endangering beach nesting habitat. Warmer sands, which are the turtles' favorite nesting grounds, the alteration in hatchlings' sex ratio, and other coastal erosion effects are also creating threats to turtles due to climate change.

If you have ever wondered why sea turtles are endangered, it is important you bear in mind that the vast majority of threats are human-related, and that some (but not all) of them can be alleviated by humans.

The Link Between Sea Turtles and Ocean Conservation

Sea turtle conservation is at the heart of ocean conservation.

Often, turtles are not focused on, but conservation is implemented on the landscape scale, as they are known to travel over a distance of thousands of miles to sea and require multiple habitat types; an ecosystem approach must be taken to conserve them.

If the turtles, coral reefs, fish, seagrass beds and all the other ocean species are covered by its marine protected areas, so are they.

In the same way, any activities that support the conservation of the ocean by reducing plastic, support sustainable fisheries and contribute to the restoration of habitats have positive impacts on the turtle's survival chances.

If one species lives, it can bring about a ripple effect.

Small Actions Make a Big Difference

Every individual can contribute to protecting sea turtles.

Simple actions include:

• Reducing single-use plastics

• Participating in beach cleanups

• Supporting sustainable seafood choices

• Respecting nesting beaches during the breeding season

• Donating to trusted conservation organizations

• Educating others about why sea turtles are endangered

  
  

These everyday choices help protect sea turtles' habitat while advancing global ocean conservation efforts.

Hope for the Future

There is good news, however, as the challenges are met.

Several populations of turtles have been stabilised or recovered around the world through the creation of better wildlife legislation, safe nesting beaches, community-based conservation programs and safer fishing methods. Conservation is successful, as shown by these success stories, where governments, scientists, local communities and individuals collaborate.

 Sea turtles are on the brink, and the future will hinge on the individuals, groups, and communities who continue to commit, educate, and act.

Final Thoughts

Sea turtles are an eloquent beauty, but that's not all they are. They support coral reefs, maintain seagrass ecosystems, support marine biodiversity and are surrogates for healthy oceans. Knowing the reasons for the "endangerment" of sea turtles is a reminder of the fact that many of the dangers are preventable, and sea turtle protection measures bolster overall ocean conservation programs.

Conserving sea turtles benefits not only the animals, but the habitat that they live in and support, which is the habitat that we live in. All efforts will be made to accommodate these incredible ocean voyagers on their amazing journey so they are able to carry on the journey for generations to come.
