Meet Arturo the polar bear who has been dubbed as the saddest polar bear and even saddest animal in the world. He also just so happens to be the last polar bear in Argentina.
The sad animal spends his day pacing back and forth in his enclosure in Mendoza Zoo, swinging his head from side to side. Arturo is thought to have become depressed ever since the death of his long-term companion two years ago.
Experts say that his behaviour is "abnormal" and that they fear he could be going insane. This is also coupled with the fact that a polar bears natural habitat is living in icy conditions with temperatures that can go low as minus 40 degrees, when in fact temperatures in his enclosure can climb as high as 40 degrees.
Protesters have been trying for months to get Arturo relocated, with perhaps the most notable campaign being from Change.org, which has accumulated nearly 62,000 signatures.
The campaign aims to move him to the Assiniboine Park Zoo in Winnipeg, Canada, where he can live a more normal life in a more natural habitat.
Sadly a recent assessment on Arturo came to the conclusion that he is too old and fragile to be moved to a new home. However that doesn't stop you from still trying to move this majestic animal to a new and better home in Canada.
