Ice Bear: A Natural and Unnatural History of the Polar Bear
Ice Bear is the definitive account of an iconic species: its life, its past, and its uncertain future. These beautiful bears are creatures of paradox: Arctic residents whose major problem is not staying warm, but keeping cool.
Officially classed as marine mammals, they are the world's largest land carnivores. They begin life in a snowdrift; at birth they weigh just twenty ounces. Fully grown, they become massive predators that can walk almost silently, ten feet in length and close to 2,000 pounds.
Wandering thousands of miles over the course of a year, they are, above all, creatures of the ice. Without sea ice and the life it supports, polar bears cannot survive.
