Nat Geo WILD's new special A Penguin's Life chronicles the everyday struggles of a colony of Emperor penguins. See firsthand how these penguin parents raise their chicks in just one season to survive on their own in the sea before the ice starts to melt. March along with these penguins as they protect their eggs in the harshest climate on Earth, trek over the ice in search of food, battle the feared leopard seal and make human parenting look easy.
