Usually lakes don't live longer than a million years but 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 from top to bottom. 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. Everyone who has been on its shores knows how unusual and how mighty it looks. The lake is very difficult to describe: its clear waters change colours all the time. The snows of Siberia come to Lake Baikal in early October. At the end of October ice begins to appear on its surface. In winter the ice gets very thick — well over a metre. (In 1904, during the Russo-Japanese War they laid a railway across the ice to carry guns to the front and the ice didn't break under its weight.) In April the ice begins to turn into water and the lake becomes so large that sailors and fishermen here talk of "going to sea". 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. Its waters move vertically, carrying oxygen to the very bottom. The lake still keeps a lot of secrets from people.

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, so the task is not at all easy. Lake Baikal can help people to understand how life developed on our planet. Now people are thinking of organizing the first national park on the shores of the lake. The lake lies among beautiful skyscrapers. Some ocean animals live in the lake. The lake's flora and fauna make it unique. The size of the lake changes with time. The water in the lake is very clean but cold, so people don't swim in it. The lake has a number of islands — big and small. Endemic means that you can not find them anywhere else on the earth.
