In the early twentieth century, rhino populations in Africa and Asia had an approximate worldwide population of 500,000. By 2011, the Western black rhino had been declared extinct by the International Union for Conservation of Nature (IUCN) and only 29,000 rhinos exist in the wild in total.
The Ranger from our visits in the Sabi Sands Game Reserve of Kruger National Park suggested that I use my GoPro to film footage of dangerous, predatory species by sticking my hand out of the safety of the vehicle close to the eye-level of the animal. This is what happened. (Surprisingly neither the leopard nor the lions even ate me).
