Sudan helped people around the world understand the threats facing rhinos everywhere. Because of demand for their horn in Eastern medicine, poaching has ravaged rhino populations. It used to be that millions of rhinos roamed across Africa and Asia; it’s estimated only about 30,000 remain between all five species combined.
Ol Pejeta is working with scientists to try to use in vitro fertilization to save northern white rhinos from total extinction. A southern white rhino would be a surrogate and carry a northern white rhino embryo created in a lab from eggs harvested from Najin and Fatu, the last female northern white rhinos. Sperm samples from now-deceased northern white rhinos are currently stored in Berlin, Germany, as a last-ditch effort to save the subspecies.
