White Alert?

With their homes melting away beneath their feet, polar bears present a painful example of the cold, hard truth behind global warming. As warmer poles eat away at ice shelves, natives like the polar bears find themselves trapped on constantly shrinking ground.

Studies with heart-wrenching results reveal that not only have polar bear numbers shrunk by one quarter in the last 20 years.... but so have their bodies. With an average height of 10ft and weight capacity of 1700 lbs, polar bears use their body fat to survive in long, polar winters when temperatures can plummet to -45 degrees celsius. However, scientists have discovered that, in their struggle for survival, most bears are now much thinner.

Four bears, recently drowned off the coast of Alaska because they were simply not strong enough to cope with a storm. Females have started giving birth to weaker twins and triplets when normally they gave birth to single, healthy cubs. As shown recently on Planet Earth, in their desperation for food, polar bears are risking their lives and trying to attack large walruses, who live in packs and often returning with crippling injuries rather than food.

Its frightening to think that my grandchildren may live in a world where they know polar bears or blue whales or rhinos as being creatures of the past which they heard stories about from their grandmother.
