Conservationists have warned that the death of the last male northern white rhinoceros in Kenya is a sign that unsustainable human activity is driving a new era of mass extinctions around the globe.
It leaves only two females - his daughter and granddaughter - through which conservationists hope they might save the species from dying out altogether using IVF.
Colin Butfield, campaigns director at WWF, said the death of a such an emblematic creature was a profound tragedy - and highlighted a wider crisis.
“There is undoubtedly a huge extinction crisis going on of which this death is just a small part,” he said.
“It is absolutely huge,” he added.
In Kenya Paula Kahumbu, director of the Wildlife Direct charity, said the news of Sudan’s death had hit people hard.
“The outpouring of grief from Kenyans, especially the younger generation, who woke up to hear that Sudan was dead this morning is a powerful reminder that we must never allow this to happen again.”
Kahumbu said people were “very angry”.”
“We did not do enough to save this majestic species. Now we must stand up and demand action – take action – to prevent the same thing happening to cheetah, elephants, black rhinos, giraffes – we must take ownership of this as Africans and educate people.”
Since then the northern white rhino was one of several sub species that has been pushed to the brink of extinction. However Sudan, who was 45, had survived. He had been moved to Dvůr Králové zoo in the Czech Republic in the 1970s before being returning to Africa, where according to those who worked in the Ol Pejeta conservancy, “he stole the heart of many with his dignity and strength”.
“He was a gentle giant, his personality was just amazing and given his size, a lot of people were afraid of him. But there was nothing mean about him,” said Elodie Sampere, a representative for Ol Pejeta.
The veterinary team said they had decided to put Sudan to sleep after his condition worsened over the weekend, leaving him with bad skin wounds. The rhino was unable to stand and was visibly suffering.
“We on Ol Pejeta are all saddened by Sudan’s death,” said Richard Vigne, Ol Pejeta’s chief executive. “He was a great ambassador for his species and will be remembered for the work he did to raise awareness globally of the plight facing not only rhinos, but also the many thousands of other species facing extinction as a result of unsustainable human activity.
“One day, his demise will hopefully be seen as a seminal moment for conservationists worldwide.”
Last night that hope was echoed by Prof Ted Benton from the University of Essex, an environmental social scientist and member of the Red-Green study group.
“The fact that this is in the news suggests there is a wider cultural feeling of regret and care about this from so many people who have never seen – and probably never expect to see – a white rhino, and that is heartening in that it shows that people care.
But he said the death was part of a “much wider and deeper issue” – the huge loss of other species.
“Through the current economic system and globalisation we are taking up more of the earth’s resources and living space than it can accommodate. This is not just a threat to other species this is a threat directly to our survival as humans too.”
Butfield said the growing recognition that we are living through an extinction crisis did offer some hope.
“We are aware of it, we know what causes it and to some extent we know what the solutions are. Now it is a matter of acting on that knowledge before it is too late.”
In Kenya Kahumbu said people were ready to fight.
“For too long conservation has been seen here a something white people do but now the young generation feel very strongly that this is for us to deal with. We need to take ownership of this issue as Africans and to make sure we act before it is too late.”
