Rhino poaching is on the rise again in South Africa, feeding appetites in Asia and the Middle East, where rhino horns are often used in traditional medicines or as cultural artefacts. South African and Asian governments, as well as Interpol, have struggled for decades to curb this illicit global trade, where each horn can fetch tens of thousands of dollars. Now, animal conservationists are trying to save South Africa's rhinos by moving them out of threatened areas and into new habitats with strong security and strategic conservation methods. The hope is that this will allow the rhinos to seed large breeding herds, protecting the species for future generations.
