I've heard that they are very threatened right now. I saw a TV News report that said 25% of the arctic ice mass has melted in the past few summers. Plus, overall, the ice caps have been reduced by 50% since NASA began photographing it in the 1960's. Since polar bears hunt mostly on sea ice, they are now very thin and on they are have little stored fat to survive the winter. I also heard that they are getting thinner every year and will most likely will be extinct in the next 10-20 years.
Polar bears can only hunt when there is sea ice, because that is how they access seals, their primary prey. As a result of global warming, sea ice has been melting earlier in the year and freezing over later in the year than it used to. This means that many polar bears do not have a long enough hunting season to build up their fat reserves so that they can survive the months without sea ice. This is causing many polar bears to starve, thus decreasing the population. Occasionally, people hunt them for trophies, which doesn't help either.
