In this August 7, 2018 photo, Zoo Keeper Mariano Narvaez trains Pupy, and African elephant at the “eco-park” in Buenos Aires, Argentina. A giraffe and a rhinoceros recently died at the former Buenos Aires zoo. Conservationists say that it is the latest sign of a poorly planned attempt by the city government to turn the 140-year-old zoo into a park and relocate most of its 1,500 animals to sanctuaries.
