Each year, more than 1000 rhinos are killed – in South Africa alone. There are fewer than 18,000 white rhinos and only 5000 black rhinos left alive in the wild. The situation with regard to this corrupt, illegal war on wildlife is clearly critical. And what are rhinos killed for? Their horns – sold in shavings as a snake-oil ‘cure’ for colds or impotence. The going price is $16,000 a kilogram, but a rhino’s horn is simply keratin, the same material as our fingernails, with no magical, medicinal properties. Grant Fowlds is a passionate conservationist on the front line of protecting these iconic animals – right now, against armed poachers; but in the longer term, too, through his work with schoolchildren, communities and policymakers.
