Polar bears 'may need to be fed by humans to survive' --Drastic measures are required to save the beleaguered animal from extinction, say scientists 07 Feb 2013 The day may soon come when some of the 19 polar bear populations in Canada, Alaska, Greenland, Norway, and Russia will have to be fed by humans in order to keep them alive during an extended ice-free season or prevent them from roaming into northern communities. Some bears may have to be placed in temporary holding compounds until it is cold enough for them to go back onto the sea ice. In worst-case scenarios, polar bears from southern regions may have to be relocated to more northerly climes that have sufficient sea ice cover. Far-fetched, draconian, and unlikely as some of these scenarios may sound, 12 scientists from Arctic countries are, for the first time, suggesting that the five nations with polar bear populations need to start considering these and other management strategies now that sea ice retreat is posing serious challenges to the bears' survival.
