Plan to save the rare Yangtze River dolphin

Conservationists have developed a plan to save one of the world's most endangered species, the Yangtze River dolphin.

The dolphin, which is found only in the Yangtze River in China, has been driven to the brink of extinction by pollution and over-fishing.

It is thought there are fewer than 50 of the dolphins left.

The conservationists hope to take some dolphins from the Yangtze and establish a breeding program in a nearby lake where they can be protected.
