Four leading environmental scientists today urged the international community to install a legal trade in rhino horn – in a last ditch effort to save the imperilled animals from extinction. In an article in the leading international journal Science the scientists argued that a global ban on rhino products has failed, and death rates among the world's remaining black and white rhinos are soaring due to illegal poaching to supply insatiable international demand. "Current strategies have clearly failed to conserve these magnificent animals and the time has come for a highly regulated legal trade in horn", says lead author Dr Duan Biggs of the ARC Centre of Excellence for Environmental Decisions (CEED) and University of Queensland. "As committed environmentalists we don't like the idea of a legal trade any more than does the average member of the concerned public. But we can see that we need to do something radically different to conserve Africa's rhino."
