What's at the Bottom of the Deepest Lake in the World

Lake Baikal in Russia is the world's deepest and oldest lake, known for its unique biodiversity and geological features. It is a Rift Valley formed by tectonic movements and is home to many species found nowhere else. The lake's hydrothermal vents support diverse life forms, including bacteria and amphipods. The Nurpa, the only freshwater seals, also inhabit the lake. However, Lake Baikal faces threats from climate change and pollution, leading to warming waters and algal blooms. Conservation efforts are crucial to preserve its natural beauty and biodiversity.
