Satiated,Polar Bears rarely attack humans unless severely provoked,whereas starving bears are extremely unpredictable and are known to kill, and sometimes eat humans. Due to warming air temperatures,ice-flow breakup is currently occurring three weeks earlier than thirty years ago,reducing dramatically the duration of the Polar bears feeding season.
Polar bears hunt seals from a platform of sea-ice. Rising temperatures cause the sea-ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food,in the late summer and early autumn. Reduction in sea-ice cover also forces bears to swim longer distances which further depletes their energy stores and occasionally leads to drowning.
The greed and overpopulation of humans is causing this global warming change, so, bearing in mind the recent sad news,let us not be too hard on the starving polar bears.
