The world’s largest land predator, the enormously powerful polar bear, has become a focal indication of the disastrous effects of sea ice melting due to global warming.  Cunning, perseverance and strength are the attributes to its successful life style.  Though the polar bear can swim about 6 miles per hour for a sustained period most marine animals can out swim it.  Long exertion out of water will overheat the polar bear.

Rocks used:  Mexican onyx-calcite-obsidian-sodolite
