Polar bear Yupi walks in her enclosure at a zoo in Morelia February 29, 2012. Mexican environmentalist groups have urged Yupi's relocation, citing the unsuitability of Morelia's climate to polar bears and the small size of the enclosure for an animal used to big open spaces. Animal welfare organizations in the U.S. and Canada have also have pushed for Yupi's relocation after zoos in Ontario and Detroit agreed to receive the polar bear, according to local media.
