All species of sea turtle are now classed as endangered. In Sri Lanka you can visit a hatchery that increases the baby turtle survival rate from 1% to 10%. Eggs are gathered from the beach and buried in a protected area. When the baby turtles are hatched they are kept for two days then released at night on the beach. You can see and hold them at the hatchery with older examples of different turtles.
