video of starving and emaciated polar bear collapsing in Canada's wilderness has gone viral on Internet. video shows bear in search of food, wandering across land with no snow or ice. creature is all skin and bones and is seen foraging for food in rusty waste containers. It is at times too weak to support its own body weight and has difficulty standing. Paul Nicklen, photographer who took video footage, stated polar bear's plight was clear sign of the devastating impact of climate change. He said filming the animal had been heart-wrenching. He explained his team were, "pushing through their tears and emotions while documenting this dying polar bear".
Mr Nicklen is part of environmental group Sea Legacy. His team was on Canada's Baffin Island to shoot documentary on conservation. He said bear they filmed was not old and probably died within hours. He said: "This is what starvation looks like. muscles atrophy. No energy. It's slow, painful death." He blamed bear's sad plight on global warming. He said: "As temperatures rise and sea ice melts, polar bears lose access to main staple of their diets - seals." Climate change is biggest threat to world’s 26,000 polar bears. video explains that bears are, "starving, and running out of energy" and are "forced to wander into human settlements for any source of food."
