Only 1 out of 1,000 hatchling sea turtles survive to adulthood, and they can live to be over 100 yrs old. green turtles are listed as endangered, and their numbers are decreasing.  They are hunted and their eggs are collected by humans, a legal practice in some countries.  Green turtles are also threatened by destruction of nesting areas and foraging areas in the sea.  Sometimes, they are accidentally caught in fishing nets, further declining their population.  Many countries are trying to protect the nesting and foraging grounds, and they are protected under many treaties and laws.
