HARI SREENIVASAN:

Off the warm waters of Oaxaca, Mexico has a new plan to protect the threatened Olive Ridley Turtle, deploying a pair of drones this week to keep watch on their eggs.

The small green sea turtles return to this stretch of coastline every year to hatch their eggs in the sand by the thousands.

But between predators and poachers, only two-tenths of one percent of these eggs survive.

They are hunted by birds, dogs and crabs or eaten by local residents.

Mexican environmental officials say their new eyes in the sky can spot people encroaching on the egg sanctuaries.
