Last Thursday, conservation groups announced that the Western Black Rhino of Africa has reached extinction. In the newly released list by the International Union for Conservation of nature, this subspecies of rhino was declared extinct while two others were shown as near extinction.
The group says that the appropriate conservation measures were not taken and need to be implemented now in order to save the white rhino, according to CNN.
But there may still be hope. NBC reports that the Javan Rhino of Asia was thought to be extinct until a small population was discovered in 1988. Other species have been saved by breeding within captivity.
