The Polar Bear

Agee is the world's first trained polar bear 1. celebrity, with films like Alaska (done as a cub) and a number of television 2. advertisements under her belt. And, she is not the only unusual animal this talented man and his wife Dawn 3. have trained. In the wild, polar bears can largely 4. be found along the shores and on sea ice in the 5. freezing Arctic region. The large 6. mammals that can weigh between 500-1,500 pounds, are the most carnivorous land animals, feeding largely off ringed and bearded seals. While they do not go 7. out of their way to attack humans, they can be very aggressive and even fatal, if they feel threatened.

Unfortunately, the melting ice caused by global warming is seriously 8. affecting the population of these cuddly bears. That's because during the summer months when they are most active, they rely on sea ice as their 9. habitat for hunting and dens. As the ice continues to melt the mammals have 10. to walk longer distances to find suitable homes and a meal.
