In 1900, the southern white rhinoceros was the most endangered of the five rhinoceros species. Fewer than 20 rhinos remained in a single reserve in South Africa. By 2010, white rhino numbers had climbed to more than 20,000, making it the most common rhino species on the planet.
Saving the white rhino from extinction can be attributed to a change in policy that allowed private ownership of wildlife. While protecting the rhinos encouraging breeding, the ranchers were able to profit by limited trophy hunting.
