Relationship with humans

Sea turtles are caught worldwide, although it is illegal to hunt most species in many countries. A great deal of intentional sea turtle harvests worldwide are for food. Many parts of the world have long considered sea turtles to be fine dining. In England during the 1700s, sea turtles were consumed as a delicacy to near extinction, often as turtle soup. Ancient Chinese texts dating to the 5th century B.C.E. describe sea turtles as exotic delicacies. Many coastal communities around the world depend on sea turtles as a source of protein, often harvesting several sea turtles at once and keeping them alive on their backs until needed. Coastal peoples gather sea turtle eggs for consumption.

To a much lesser extent, some species are targeted for their shells. Tortoiseshell, a traditional decorative ornamental material used in Japan and China, comes from the carapace scutes of the hawksbill sea turtle. Ancient Greeks and ancient Romans processed sea turtle scutes (primarily from the hawksbill sea turtle) for various articles and ornaments used by their elites, such as combs and brushes. The skin of the flippers is prized for use as shoes and assorted leather goods. In various West African countries, sea turtles are harvested for traditional medicinal use.

The Moche people of ancient Peru worshipped the sea and its animals. They often depicted sea turtles in their art. J. R. R. Tolkien 's poem " Fastitocalon " echoes a second-century Latin tale in the Physiologus of the Aspidochelone ("round-shielded turtle"); it is so large that sailors mistakenly land and light a fire on its back, and are drowned when it dives.

Beach towns, such as Tortuguero, Costa Rica, have transitioned from a tourism industry that made profits from selling sea turtle meat and shells to an ecotourism-based economy. Tortuguero is considered to be the founding location of sea turtle conservation. In the 1960s the cultural demand for sea turtle meat, shells, and eggs was quickly killing the once-abundant sea turtle populations that nested on the beach. The Caribbean Conservation Corporation began working with villagers to promote ecotourism as a permanent substitute to sea turtle hunting. Sea turtle nesting grounds became sustainable. Tourists love to come and visit the nesting grounds, although it causes a lot of stress to the sea turtles because all of the eggs can get damaged or harmed. Since the creation of a sea turtle ecotourism-based economy, Tortugero annually houses thousands of tourists who visit the protected 35-kilometre (22 mi) beach that hosts sea turtle walks and nesting grounds. Walks to observe the nesting sea turtles require a certified guide and this controls and minimises disturbance of the beaches. It also gives the locals a financial interest in conservation and the guides now defend the sea turtles from threats such as poaching; efforts in Costa Rica's Pacific Coast are facilitated by a nonprofit organization, Sea Turtles Forever. Thousands of people are involved in sea turtle walks, and substantial revenues accrue from the fees paid for the privilege.

In other parts of the world where sea turtle breeding sites are threatened by human activity, volunteers often patrol beaches as a part of conservation activities, which may include relocating sea turtle eggs to hatcheries, or assisting hatching sea turtles in reaching the ocean. Locations in which such efforts exist include the east coast of India, São Tomé and Príncipe, Sham Wan in Hong Kong, and the coast of Florida.
