Wild Alaska

Alaska is a unique wilderness marked by extremes. Its northerly position on the Arctic Circle means winters can be bitterly cold, while in summer, the size and shape of the land brings heat waves. This series explores spring, summer and winter in this extreme wilderness and discovers the unique species that have learned to thrive in these harsh conditions. Also included in this collection is 24 Hours on Earth, a two-part series which examines the animals and plants which have evolved astonishing strategies to exploit key moments in the 24 hour rhythmic cycle of our planet.
