Polar bear population could fall by 30 per cent in a year: study http://apocadocs.com/s.pl?1275068471
A mathematical analysis for the first time has uncovered the prospect of a sudden, dramatic decline among Canadian polar bears as they starve to death.
"This is much, much different. This is not a gradual change," said Dr. Andrew Derocher, one of the world's leading polar bear authorities and co-author of the study. "We're looking at a decrease by 20 or 30 per cent or even much more in a year."....Scientists factored in the shrinking sea ice, which affects how many seals the bears can eat before they hibernate and how easily they can find mates. Without enough food or opportunity, mating is less successful, fewer, less robust cubs are born, and teenage bears spend longer "wandering around trying to find something to eat."

Great, just when we thought it was safe to stop worrying about the polar bears (in lieu of worrying about the oil drenched pelicans, etc.), now this!
