So pointing out the OBVIOUS to those actually paying attention is fear mongering?
How bout getting urself informed.

Polar bears are NOT going extinct.[/QUOTE]
Ask the Experts: Are Polar Bear Populations Increasing?
Question: I'm confused about polar bear numbers. Some news reports state that polar bears should not be listed as a threatened speciesthey state that, in fact, their numbers are actually increasing. For example, the following paragraph appeared on the Fox News Web site:
"In the 1950s the polar bear population up north was estimated at 5,000. Today it's 20- to 25,000, a number that has either held steady over the last 20 years or has risen slightly. In Canada, the manager of wildlife resources for the Nunavut territory of Canada has found that the population there has increased by 25 percent."
If this is true, then why are scientists worried about population declines?
First, it's important to note that scientists lack historical data on polar bear numbersthey only have rough estimates. What we do know, though, is that in the 1960s, polar bear populations dropped precipitously due to over-hunting. When restrictions on polar bear harvests were put in place in the early 1970s, populations rebounded. That situation was a conservation success story ... but the current threat to polar bears is entirely different, and more dire.
Today's polar bears are facing the rapid loss of the sea-ice habitat that they rely on to hunt, breed, and, in some cases, to den. Last summer alone, the melt-off in the Arctic was equal to the size of Alaska, Texas, and the state of Washington combineda shrinkage that was not predicted to happen until 2040. The loss of Arctic sea ice has resulted in a shorter hunting season for the bears, which has led to a scientifically documented decline in the best-studied population, Western Hudson Bay, and predictions of decline in the second best-studied population, the Southern Beaufort Sea.
Both populations are considered representative of what will likely occur in other polar bear populations should these warming trends continue. The Western Hudson Bay population has dropped by 22% since 1987. The Southern Beaufort Sea bears are showing the same signs of stress the Western Hudson Bay bears did before they crashed, including smaller adults and fewer yearling bears.
At the most recent meeting of the IUCN Polar Bear Specialist Group (Copenhagen, 2009), scientists reported that of the 19 subpopulations of polar bears, eight are declining, three are stable, one is increasing, and seven have insufficient data on which to base a decision. (The number of declining populations has increased from five at the group's 2005 meeting.)
Some members of the press take advantage of the complexity by stating that "polar bears are not in troubletheir numbers have doubled since the 1960s." That's a disingenuous statement, of course. It is true that polar bear populations rebounded after over-hunting was restricted, but that situation has nothing to do with the threat polar bears now face: the loss of the sea ice habitat essential to their survival.
