turtles. If a turtle eats a plastic bag, it tends to clog the turtle's digestive system and result in the animal dying. There have been many cases of dissection showing plastic and other debris inside turtles' stomachs and intestines. Marine debris has caused mortality in all species of sea turtles. There have also been cases where sea turtles have been found with plastic straws in their noses, plastic bags or toothbrushes in their stomachs, or fish hooks stuck on their flippers. Plastic straws can be dangerous to sea turtles, too, because they are often mistaken for food. This can cause the sea turtle to choke or die of starvation because they feel full and do not eat, when they are actually full of plastic. Despite being small, plastic straws are among the top items that pollute the ocean. As previously mentioned, ingestion is also more likely to occur if the plastic resembles their typical food. Studies have found that turtles had a 50% chance of dying if they ingested more than fourteen pieces of plastic

human-made lights are brighter than celestial lights, causing sea turtles to move toward them. A sea turtle not going in the direction of the ocean is referred to as a disorientation event. Disorientations lead to an increased risk of predation, exhaustion, dehydration, and/or injury. These events are often fatal. Disorientations can be caused by any light source that is directly or indirectly seen from the beach. Also, heavily lit beaches may cause an adult to have a false crawl. This is when the female decides the beach is not suitable for her nest and goes back to the water. False crawls cause exhaustion for the adult and may lead to her releasing her eggs in the ocean. This would be fatal to all the eggs.
220: 351: 82: 243:. Blunt force trauma is from the hull of the boat hitting the turtle and results in a cracking, less obvious, injury on the turtle's carapace. Propeller strikes form clear cut, parallel lines on the carapace of the turtle. The propeller wounds can cut into the spinal cord or lungs if deep enough, as these are located dorsally on the animal attached to the underside of the carapace. Sea turtle stranding data is the primary method of quantifying boat strike injuries, which has increased by 20% in 320: 17: 391: 69:
cages. The effects of the use of steel mesh as a cage material may not be known for many years until assessments can be made of the success rate of the first adult populations that developed within such cages begin attempting landfall for nest-making. Gravid turtles or their hatchlings may also be affected by the presence of magnetic fields arising from power cables, iron debris, steel seawalls or other human activities that locally modify

effects excessive lighting has on sea turtles and there have been substantial attempts to darken beaches and replace harmful artificial lighting with turtle-safe lights. Coastal communities have also been creating and updating their lighting ordinances with the common goal to help save sea turtles. Lighting ordinances allow local governments to enforce safer lighting for sea turtles.

In 1963, the Marine Turtle Group was created by the chairman of the Survival Service Commission of the International Union for the Conservation of Nature and Natural Resources as the first international forum for sea turtle research and conservation. In the United States in 1973, the 497:
turtles' injuries are so severe that they can never become healed to the extent of being able to survive on their own outside of the facilities, hundreds of the patients from both the Gordon and Patricia Gray Veterinary Hospital in Juno Beach and the Sea Turtle Hospital in Topsail Island have been successfully rehabilitated and released in the last couple of decades.
342:, while others claim that eating them yields longevity. In some islands, parts of the sea turtle are used in ceremonies and are considered sacred. Other times, the carcasses harvested are made into jewelry, instruments, souvenirs, sunglasses, or wall decorations, especially hawksbill sea turtles, which are desired for the striking details of the shell. 515: 461:(USFWS) to enforce the ESA with regards to sea turtles. USFWS is responsible for all sea turtle conservation on nesting beaches and NOAA Fisheries are responsible for the marine conservation of sea turtles. The conservation of sea turtles on an international scale has been led by two major environmental agreements: the 429:. These tumors are either smooth or contain pointed projections and they are red, pink, grey, black, or purple in color. These tumors are usually located anywhere on the soft skin tissue of the sea turtle, either the neck, eyes, or bottom of the flippers and range in size anywhere from a pea to a grapefruit. 465:– South-East Asian Marine Turtle Memorandum of Understanding and the Inter-American Convention for the Protection and Conservation of Sea Turtles.

As awareness of the negative impact artificial lighting has on sea turtles has grown, there have been several large-scale conservation efforts by Marine Life programs and conservation groups to educate the public on turtle conservation.

habits of sea turtles increase their exposure to marine pollution at each of the stages of their lives including eggs, hatchlings, juveniles, sub adults, or nesting adults. In a 1994 study off of Florida's Atlantic coast, 63% of hatchlings surveyed were found to have ingested tar. Loggerheads in

Ferrous metal wire mesh screens are commonly used to protect sea turtle nests from predators' excavating and devouring the eggs and hatchlings. A new concern is that nestlings' delicate magnetic sense may not develop normally in the presence of the magnetic field interference from these steel mesh

Owing to the popularity of numerous sea turtle species, people often travel to areas where the turtles nest, live to observe and photograph them. This has resulted in numerous deaths of the turtles through boat collisions, tourists attempting to catch or steal individuals, and other incidents. In

between 1985 and 2005. In general, sea turtles are not able to avoid boat collisions when boats are travelling too quickly. Also, the faster a boat is travelling the more damage is done to the turtle, making incidents more lethal. When sea turtles surface to breathe they continue swimming in the

Sea turtles existing in the exact areas where oil spills occur are not the only ones at risk due to the strong and far reaching ocean currents which can move pollution to great distances from its derivation. 409:.
