Not everyone knows that rhinoceros horns are used in Asia as "traditional medicine". And for six years by poachers in Zimbabwe killed more than a thousand rhinos. On the black market price of a large rhino horn is up to 360,000 U.S. dollars. In order to save the rhino poachers from killing, the official authorities and veterinarians have to saw off the horns by the animals, and they comply with all necessary medical precautions.
