Threats on sea turtles

Threats:
- continuing loss of nesting habitat & environmental damages from structure building

- tourist use of beaches result in disturbance to nesting turtles
(Egg laying can be aborted or delayed as well)

- Artificial lighting has negative effects on nesting behaviour and success
(turtles can mistakenly move inland after egg laying)

- practice of adding sand onto a beach to rebuild affects turtles by direct burial of nests

- mechanical equipment for beach cleaning that result compacted beaches that are difficult for nesting

- predators
main: Homo sapiens
others: raccoons, sharks, gulls, foxes, snakes.....)

- dirty environment
(rubbish in sea or land, oil and gas)
