The rhino horn auction in South Africa is a serious setback in the fight against poaching and the survival of wild rhinos. The chances of the horns remaining in the country are next to zero.
Rhino horn trade is a hotly contested topic. Proponents believe it can aid conservation efforts. But those in opposition believe it will cause poaching to increase.
Dehorning is practised on many South African private reserves and is seen as a way of deterring poachers.

A few national parks and reserves want to dehorn rhinos and there is a lobby for a regulated and closely monitored legal trade in rhino horn. But this is met by opposition from many.
