GENEVA — The Western Black Rhino of Africa was declared officially extinct Thursday by a leading conservation group.
The International Union for Conservation of Nature said that two other subspecies of rhinoceros were close to meeting the same fate.
The Northern White Rhino of central Africa is now "possibly extinct" in the wild and the Javan Rhino "probably extinct" in Vietnam, after poachers killed the last animal there in 2010.
A small but declining population survives on the Indonesian island of Java.
IUCN said Thursday that a quarter of all mammals are at risk of extinction, according to its updated Red List of endangered species.
'Stewards of the Earth'
But the group added that species such as the Southern White Rhino and the Przewalski's Horse have been brought back from the brink with successful conservation programs.
"Human beings are stewards of the Earth and we are responsible for protecting the species that share our environment," said Simon Stuart, chair of the IUCN Species Survival Commission.
"In the case of both the Western Black Rhino and the Northern White Rhino, the situation could have had very different results if the suggested conservation measures had been implemented," he added. "These measures must be strengthened now, specifically managing habitats in order to improve breeding performance, preventing other rhinos from fading into extinction."
its very sad.
