Answer 2

Lake Baikal is the world's deepest lake, reaching a maximum depth of 1,620 meters (5,315 feet). Not only is it the deepest lake globally, but it is also the oldest and one of the clearest. Located in Siberia, Russia, Lake Baikal is a UNESCO World Heritage site and is often referred to as the "Pearl of Siberia."

The lake is known for its remarkable biodiversity, hosting around 1,500 different species of animals, with an astonishing 75% of these species found nowhere else on Earth. The most famous and emblematic species of Lake Baikal is the Baikal seal, or nerpa, which is the only freshwater seal species in the world.

Lake Baikal is surrounded by mountain ranges, with the most notable being the Baikal Mountains to the north and the Barguzin Range to the northeast. The lake itself is approximately 636 kilometers (395 miles) long and 80 kilometers (50 miles) wide, making it the seventh-largest lake in the world by surface area.

The lake's drainage basin is extensive, covering about 557,000 square kilometers (215,000 square miles). The Angara River is the only river that flows out of Lake Baikal, eventually joining the Yenisei River.

One of the unique features of Lake Baikal is its transparency. The water is exceptionally clear, allowing visibility to depths of over 40 meters (130 feet). This clarity is due to the lake's oligotrophic nature, meaning it has low nutrient levels, resulting in a pristine and almost untouched ecosystem.

Approximately 90% of the population of Eastern Siberia resides in the vicinity of Lake Baikal. The city of Irkutsk, located to the northwest of the lake, is a major urban center in the region. The lake and its surrounding areas also attract a significant number of tourists, with around 500,000 visitors exploring its shores each year. The tourism industry around Lake Baikal has been growing steadily, driven by the lake's natural beauty, unique biodiversity, and cultural significance.

In conclusion, Lake Baikal is a natural wonder with its extreme depth, unparalleled biodiversity, and stunning surroundings, making it a globally significant and cherished environmental treasure.
