All seven species of marine turtle face multiple threats including bycatch, plastic ingestion, nesting beach disturbance, and climate change affecting nest sex ratios.
Turtles entangled in fishing gear drown over extended periods. Those that surface for air but remain entangled suffer extended distress before death or rescue. Plastic ingestion causes prolonged suffering as turtles cannot pass or regurgitate plastic. Light pollution from beach development disorients nesting females and hatchlings. Boat strikes cause traumatic injuries requiring expensive rehabilitation. The scale of human-caused mortality vastly exceeds the capacity of rehabilitation programs.
