Over 550K Sign Petition to Help 'Lonely Bear'

Arturo might feel better if he knew how many people want to help him. The polar bear, who seems miserable in an Argentinian zoo, could end up relocated to a zoo in Canada if social-media activists get their way, NPR reports. A Change.org campaign has over 550,000 votes as of this writing, and even Newt Gingrich is on board, urging people on his Instagram page to lend their support (but not linking directly to the petition, the Washington Post notes). Arturo has been walking miserably around his warm enclosure, shaking his head and baring his teeth, since losing his lifelong companion bear Paula. But some experts say he's too old and fragile to be moved thousands of miles to colder climes. Click for more on the Arturo debate. (More polar bear stories.)
