When photographer Paul Nicklen and filmmakers from conservation group Sea Legacy arrived in the Baffin Islands, they came across a heartbreaking sight: a starving polar bear on its deathbed.
In the days since Nicklen posted the footage, he's been asked why he didn't intervene.
"Of course, that crossed my mind," said Nicklen. "But it's not like I walk around with a tranquilizer gun or 400 pounds of seal meat."
And even if he did, said Nicklen, he only would have been prolonging the bear's misery. Plus, feeding wild polar bears is illegal in Canada.
The wildlife photographer says he filmed the bear's slow, beleaguered death because he didn't want it to die in vain.
"When scientists say bears are going extinct, I want people to realize what it looks like. Bears are going to starve to death," said Nicklen. "This is what a starving bear looks like."
THE CLIMATE CHANGE LINK
By telling the story of one polar bear, Nicklen hopes to convey a larger message about how a warming climate has deadly consequences.
Polar bears have long been unwitting mascots for the effects of climate change. As animals that live only in Arctic regions, they're often the first to feel the impacts of warming temperatures and rising seas.
The large, half-ton bears find concentrations of seals on sea ice. During summer months, it's not uncommon for polar bears to go months without eating while they wait for Arctic ice to solidify.
In 2002, a World Wildlife Fund report predicted that climate change could eventually lead to polar bear endangerment or extinction. Even then, the report found that polar bears were moving from ice to land earlier and staying on land longer, unhealthily extending the bears' fasting season. By the end of summer, most bears studied by the World Wildlife Fund showed signs of starvation.
