The Singapore Zoo said Friday it will keep its male polar bear _ reportedly the only polar bear to be born in the tropics _ in a reversal of its earlier decision to move it to a temperate country, while animal rights activists urged the zoo to improve conditions in the bear's enclosure, REPORTED AP. The zoo's parent company, Wildlife Reserves Singapore, said its animal welfare and ethics committee had recommended that Inuka, the 17-year-old bear, remain at the Southeast Asian zoo because of the risks involved in moving it. «The transport of a full grown polar bear to an institution in a temperate country will be a stressful situation and carries its own share of risks, most extreme being that Inuka may die during transportation or during the introduction process in the new facility,» the company said in a statement. The zoo had said last year that Inuka would be moved to a country with a temperate climate after his mother dies, following a Singapore animal rights group's complaints that the bears were showing signs of distress. Polar bears normally spend most of their lives on sea ice. In Singapore, Inuka and his 30-year-old mother, Sheba, are kept in an open and partly shaded enclosure that is cooled by misting fans and includes a pool. The bears can also use an off-exhibit air-conditioned den.
