Rendani Nethengwe is one of the most experienced rangers in South Africa's Kruger National Park and responsible for the protection of the animals. He sometimes fights poachers who ruthlessly slaughter elephants for their ivory tusks.
Park ranger Rendani Nethengwe holds out a bloody cartridge he has just cut out of the carcass of a dead elephant. "It's sad," he says. "Poachers are destroying our future - the animals are our capital, they bring tourists and money into the country." Nethengwe is one of the most experienced rangers in the South African national park, responsible for the protection of animals in every respect: sometimes fighting poachers, sometimes working with veterinarian Peter Buss. He is currently very worried about the elephants in the game reserve after identifying the human tuberculosis pathogen in a blood sample taken from a dead one. Now he regularly takes blood samples from all the animals. Wild dogs are among the rarest animals in the park but things are looking up. "We now have a really big pack of them here in the park again," says zoologist Antoine Marchal, who has been bringing the dogs together in a group. That normally ends in bloody carnage - but this time it has created a happy family instead. In any case, wild dogs need to hunt large in large packs to survive. Something that started as an experiment now promises to save the rare canines from extinction.
