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.

This photo taken on August 14, 2018 shows a caged bear during a rescue operation from a facility where bear bile is extracted in Thai Nguyen province. Bear bile is extracted – often continuously and painfully – from the animals' gallbladders and used in traditional medicine in Vietnam, where the illegal practice remains widespread. But consumers are shunning the farmed version in favour of bile taken from the nearly extinct wild bear population, which can cost 12 times more, and farmers can no longer earn what they used to from the illicit trade.
