It dawned on me that we have a real problem here. The POSSIBILITY this exists is frightening, too much to think and/or mention, but here I go anyway, venturing into no man’s land.
The problem? The potential of all kinds of bears becoming extinct, EXCEPT polar bears. Why is this a problem? Logically speaking, there can not be a POLAR bear if there are no bears to begin with, for there is only one type of bear: The Polar Bear. How will scientists cope? Will they rename the Polar Bear to just "Bear"? Note that WHITE Bear won’t work either because there are no other variety of bears. By saying it is a White Bear, you insinuate that there are BLACK bears too. Hell, maybe even green bears.
Actually, knowing how our convenient modern society works, it wouldn’t surprise me that the name Polar Bear would stick, much like how a tomato is considered a vegetable stuck. (THAT’S RIGHT. I got news for you Walter Cronkite: IT’S NOT A VEGETABLE). How convenient! There are POLAR bears, but no regular bears! Actually, thanks to global warming (maybe) Polar Bears will be extinct. Unless they mutate and gain the rapid adaptability to survive in the warmth of the tropic. Then I guess they’d be the Unpolar Bears. Sounds like a slogan of a soft drink from the 90s... Hm.
