Lake Baikal

 

Lake Baikal

Lake Baikal is an immense freshwater expanse of 31,722 square kilometres under UNESCO protection. It is known for its unique ecosystems and pristine drinking water. Due to climate change, the lake's surface temperature during the summers of recent years has increased significantly, triggering numerous surface eutrophication effects and threatening the biodiversity of this fragile and precious ecosystem.
