Asleep in appearance, lakes hide a secret life, and obey natural cycles. In this episode, we look at the animal and plant life that populates Lake Baikal, recognised as the largest freshwater reserve in the world. Located in the heart of Siberia, Lake Baikal offers the purest waters on the planet. Despite a harsh climate, neither ice nor wind hinder the development of its unique fauna and flora.
