The Secrets of the Polar Regions — a new edition in the Jean-Michel Cousteau Presents series (formerly titled Glaciers: Life at the Frozen Edge ) — presents timely information on the South and North Poles. The book clearly explains the geology of glacier and iceberg ecosystems of these remote but crucially important realms and reveals the fascinating adaptations of the animal and plant life living on or near the ice. Animals profiled include seals, sea lions, walruses, wolves, polar bears, Arctic foxes, musk oxen, yaks, and snow leopards. Even tiny creatures like the fascinating glacier flea that freezes solid every night butawakens to search for pollen the next day are included. Throughout, the book presents an up-to-date discussion on the implications of global warming and icecap melt.
