Animals on Ice
It sounds like science fiction, but it’s real life. It’s also the promise of hope—a safeguard against the worst. At the San Diego Zoo Institute for Conservation Research®, special freezers preserve the genetic material of 10,000 animals from 1,000 different species. This is our Frozen Zoo®, and it’s our hope for the future of conservation.
The Future in a Freezer
The Institute for Conservation Research®, part of San Diego Zoo Global, is the largest zoo-based science and conservation center in the world. In recent years, we’ve pioneered the use of science in bringing species back from the brink of extinction.
We were the first to use artificial insemination to help save giant pandas—something no one thought was possible. And while there is still a lot of work to be done, giant pandas have been downgraded from endangered to “threatened.” Now, we’re working on using our decades of scientific knowledge and research to launch a surrogate rhino mother program that will bring the northern white rhino back from the brink of extinction.
Rhinos in Peril
With only two animals remaining on the planet, the northern white rhino is the most endangered animal on Earth. Decades of rampant poaching have wiped out these gentle giants, and science is the only hope for bringing them back.
The remaining northern white rhinos live under armed guard in a sanctuary in Kenya. Due to their age and certain health conditions, none of them are able to breed. But with the help of our Frozen Zoo® and our six rescued southern white rhino females, we have a plan to bring this species back.
We have cryogenically preserved the genetic material of 12 northern white rhinos, and we are working on a program that will allow us to use it in surrogate pregnancies. Since southern white rhinos are genetically very similar to their northern cousins, we’re optimistic that our southern white rhino females will be successful in carrying surrogate pregnancies. While some might see these measures as controversial, the fact remains: rhinos are only going extinct because of humans, and we owe it to them to bring them back.
San Diego Zoo Global is no stranger to conservation “controversy.” In 1982, there were just 22 California condors left on the planet. We didn’t know much about them, but we knew that we had to try to save them.
Some people thought we should let these magnificent birds die out. But condors, like rhinos, were only threatened because of humans. Today, thanks to those intrepid scientific efforts, more than 500 California condors have been born, and more than half of them fly free in the wild. We have a long road ahead of us with our white rhino surrogacy program, but we have so much hope for the future of these magnificent giants. Stay tuned.
