TODAY is World Ranger Day. It's a day to commemorate Rangers killed or injured in the line of duty and to celebrate the work Rangers do to protect the planet's natural treasures and cultural heritage. Today's Rangers Day comes days after Anton Mzimba, the Head Ranger at Timbavati Private Reserve in Hoedspruit, Mpumalanga, was murdered in front of his family onTuesday night. The murder has been described as a 'hit' in which the killers drove up to his house, shot him dead, and drove off. Anton Mzimba is among 12 rangers who died in the line of duty over the past 2 years.  Joining us on the line is Tinyiko Golele, a female regional ranger based at Skukuza camp in the Kruger National Park.....
