#FreeArturo Aims to Get "Depressed" Polar Bear Out of Argentine Zoo

Arturo the polar bear calls Argentina home. His address is the Mendoza Zoo, where he has a small pool to cool off. But he's out of his natural habitat in the Southern Hemisphere, where summer temperatures can get up to 90 degrees.

Arturo is the last bear left in Argentina after his longtime companion, Pelusa, died at age 30 in 2012. They had been mates for two decades, and she had given birth to cubs, though none of them survived. Ever since, experts say he has become increasingly more "depressed." He's alone. He looks sad. And he appears uncomfortably hot.

That doesn't sit well with online protesters, who are calling on Argentina's president to improve living conditions for the over 850-pound polar bear. So far more than 180,000 people have signed a Change.org petition to move Arturo to Canada.

Cher has cried foul about Arturo's plight over Twitter, and even Newt Gingrich is raising awareness with his sad face on Instagram using #freearturo.
