‘A great ambassador for his species’: world’s last male northern white rhino dies
Rhinos have few predators in the wild due to their size. However, demand for rhino horn in traditional Chinese medicine and dagger handles in Yemen fuelled a poaching crisis in the 1970s and 1980s

Sudan, the last male northern white rhino, has died in Kenya at the age of 45, after becoming a symbol of efforts to save his subspecies from extinction, a fate that only science can now prevent.
When Sudan was born in 1973 in the wild in Shambe, South Sudan, there were about 700 of his kind left in existence.
At his death, there are only two females remaining alive and the hope that in vitro fertilisation (IVF) techniques will advance enough to preserve the subspecies.
Sudan, elderly by rhino standards, had been ailing for some time, suffering from age-related infections, according to his keepers at the Ol Pejeta Conservancy.
“His condition worsened significantly in the last 24 hours; he was unable to stand up and was suffering a great deal. The veterinary team … made the decision to euthanise him.”
Sudan lived out his final years on a 90,000-acre (36,400-hectare) reserve of savannah and woodlands in central Kenya, along with the two remaining females, under armed guard to protect them from poachers.
