“In the Informants Shoes,” a series by #NatGeoExplorer @tarankeir investigates the socioeconomic drivers behind rhino poaching in Greater Kruger, South Africa through visual storytelling. Seen here, she details the faces of rangers who are immersed in the crisis, painting them in a manner so as to not reveal their identities. One ranger in particular “has seen the transition of the park ranger role from pre-rhino poaching to deep within the crisis. The changes are drastic, the sacrifices real, and the psychological toll of being a rhino protector is immense,” Keir says. Further explore their stories and more deeply examine the challenges rangers face in Kruger at the link in @tarankeir’s bio. Video by @tarankeir #WorldRhinoDay
