Planet SOS: New technology can save rare rhino

Scientists are developing a robotic tool which can save one of the world’s rarest creatures.

They say an unprecedented wave of wildlife extinction is underway because of global warming, a loss of habitat and poaching.

They are trying to save some critically-endangered species, including the Northern White Rhino, which has been hunted to obliteration.

The project aims to produce a self-sustaining herd of Northern White Rhinos, first in captivity and then returned to the wild in Africa.
