In this July 5, 2016 photo, a tapir rests its hooves on the edge of an opening of an enclosure at the former city zoo now known as Eco Parque, in Buenos Aires, Argentina. Conservationists complain that a year after the transformation from zoo to park, the remaining animals still live in antiquated enclosures widely considered inhumane by modern standards.
