More than one rhino is being killed in South Africa by poachers each day — with 2012 on target to be the worst year on record.
Some 159 rhinos have fallen victim to poachers since January, a death toll that looks set to surpass last year’s grim figure of 449. In 2007, only 13 were killed in the country.
