Unbearable

Polar bear is an animal that can survive under execrable and severe cold environment. They live beautifully in a frozen shining world that off the beaten path and become a scenery in the ice space.
However, this originally solid paradise is melting acceleratingly day by day. Polar bears no longer love leisurely but feel fear and disturbed piece by piece. It's more and more difficult for them to gain a foothold. The beautiful world becomes unbearable.
