Penguins and Polar Bears

Book excerpt: We all know that ice bears and penguins never meet (except in zoos), but what else do you know about the Arctic and the Antarctic (or polar) regions? Did you know that Antarctica is not just the coldest, but also the driest continent on Earth? Have you ever wondered how a polar bear stays warm in the Arctic? Sitting on the most extreme North and South Poles are two of our planet's most mysterious regions, but what similarities and differences do they share? Polar tales the incredible geography of both regions, how polar bears and penguins survive, and introduces the explorers who dared to travel into these unknown spots on Earth in the past. We go under their oceans and discuss the effects of climate change.
