Why in news?
Lake Baikal often appears in discussions about superlative geographical features and environmental conservation. With remarkable statistics and unique biodiversity, it remains a favourite topic for exams and general knowledge.
Background
Located in south‑eastern Siberia, Lake Baikal occupies about 3.15 million hectares (31,500 square kilometres). It formed as a rift valley roughly 25 million years ago, making it the oldest existing freshwater lake. The lake reaches a depth of about 1,642 metres, which makes it the world’s deepest. Despite its modest surface area, it contains roughly 20 percent of the planet’s unfrozen fresh water (about 23,000 cubic kilometres). Because of its age and isolation, more than 1,000 plant and animal species found here occur nowhere else, including the freshwater Baikal seal.
Significance
- Ecological value: The lake’s unique fauna provides scientists with insights into evolution and adaptation. Its nicknames, “Galápagos of Russia” and “Pearl of Siberia,” reflect this richness.
- UNESCO status: Lake Baikal was inscribed as a UNESCO World Heritage site in 1996 under natural criteria emphasising its exceptional beauty, geological history and biodiversity.
- Environmental pressures: Industrial pollution, tourism and climate change threaten the lake’s ecosystem. Conservation laws and protected areas around the shoreline seek to limit these impacts.
Conclusion
Lake Baikal stands out for its age, depth and volume. Protecting this natural wonder is vital not only for Russia but for global freshwater heritage.
