Here's a seriously depressing question:
If a polar bear no longer has ice to stand on and must have his "bear kibble" (that's a real term; more on it soon) airlifted to the Arctic by helicopter, is he still a polar bear? Or is he some sort of zoo-like experiment -- a sad but perhaps unavoidable consequence of an era of melting ice and warming climates?
I posed a less-wordy version of that question to Andrew Derocher, a biologist and polar bear expert at the University of Alberta. He recently published a paper outlining several emergency actions that likely will have to be taken soon to save the Arctic bears.
