An emaciated polar bear, which was found roaming on the street in the industrial city of Norilsk, Russia earlier this week, was transported to a zoo in the Siberian city of Krasnoyarsk for treatment on Friday. /VCG Photo

The two-year-old female polar bear was spotted extremely ill and almost died after scavenging for food on a rubbish heap in Norilsk. /VCG Photo

So far, it remained unclear how the animal got to the city. But environmentalists said that some animals were being forced farther south to seek for food as the temperature in the Arctic rises. /VCG Photo
