this patrol. but in this vast territory, the drones and patrols can only cover. so ground. in the few days we're here, four rhinos were killed. many of the rinl owes that survive these attacks are brought here to this nearby sanctuary. >> high, big fello. somebody messed you up. somebody got paid off you, big guy. >> like this mother and her calf. >> we hear poaching all the time. look at this animal. first time i'm seeing it in my life up close and personal. but just, i mean, until you're this close to it. that is brutal. >> three months ago rescuers found her in the bush, still groggy. her horn hacked off. left for dead. her baby clinging to her side. >> is the animal still in pain? >> no. >> as much as we can get a success. >> she is healing well and soon
into the reserve. >> man oh man. it's a shame this place is even necessary. >> it is almost unfathomable to think, what would drive someone to this kind of brutality, until you realize a single rhino horn can fetch up to a quarter million dollars on the black market. even a small fraction of that is hard to resist in a place with little opportunity. >> we're in a township outside pretty pretoria. our poacher set up a meeting for us. >> a former poacher has agreed to meet us. only if we don't show his face. >> did you ever feel bad for what you were doing for killing these animals? >> through a translator he said he felt bad but needed money to feed his family.
