Scientists say that Lake Baikal is the oldest lake on planet Earth. 
This wonderful lake is more than 25 million years old! For scientists it is a living laboratory of evolution. 
Lake Baikal is also the deepest lake in the world, it is 1,637 metres deep. With time the lake becomes wider and deeper. There is a theory that Lake Baikal is the beginning of a new ocean. The lake holds one-fifth of the planet’s fresh water and this water is incredibly clean. 
Lake Baikal is one of the most beautiful places on the Earth.

The water in the lake is never warm. In summer its temperature is about +12 degrees. But a lot of people still enjoy swimming in it. They say swimming in the waters of the lake is good for their health. 
Lake Baikal is a living museum of water plants and animals. About 1,500 species of animals here are endemic. Endemic means that you cannot see them anywhere else in the world. The lake is rich in life. The lake still keeps a lot of secrets from people. One great mystery about the lake is how nerpa, the Baikal seal, appeared in the lake which is hundreds of kilometers from any ocean, and made the lake its habitat. 
The lake lies among beautiful mountains. The Baikal Mountains on the north shore and the taiga belong to a national park. The greatest problem here is to keep all this natural beauty and protect the lake from pollution. Every year the lake attracts more and more tourists. 
1. Lake Baikal can help people to understand how life developed on our planet. 
2. The size of the lake changes with time. 
3. The water in the lake is very clean but cold, so people don’t swim in it. 
4. The lake has a number of islands — big and small. 
5. The lake’s flora and fauna make it unique.

7. Now people are thinking of organizing the first national park on the shores of the lake.
