Перескажите текст на английском
Lake Baikal, in eastern Siberia, is a miracle of nature. It's the deepest lake on Earth and it contains more water than all the Great Lakes of America put together. It's also the oldest lake on Earth and, after more than 25 million years, Lake Baikal is still growing at a rate of 2 cm a year. However, facts and figures fail to describe the breathtaking beauty of Baikal. The water is crystal clear, and when you can see the shimmering stones on the bottom of the lake it's hard to believe they're so deep down. But then this tranquillity can easily become a tempest. As the lake changes its mood, the wind rises and huge waves begin to roll across the surface.
Lake Baikal is surrounded by some magnificent mountain ranges, such as the Primorsky, Baikalsky and Barguzinsky. More than 300 rivers flow into Lake Baikal and only one river, the Angara, flows outwards. Of the 22 islands in the lake, the most famous is Olkhon Island, where they say the sun shines brightly for more than 300 days a year. Olkhon is a place of legend and wild spirits, and it's home to the famous Shamanka,where shamans used to live in times gone by.
This environmental treasure also contains a wealth of biodiversity. Most of the 2,635 species of animals and plants discovered in and around Lake Baikal cannot be found anywhere else in the world. The lake is also the only breeding ground for the Baikal Seal and the Omul fish, on which they feed. In 1996, Baikal was declared a UNESCO World Heritage Site. The total area of the site is 8.8 million hectares, which includes the lake's surface, three reserves, and two national parks, Pribaikalsky and Tunkinsky.
Today, this precious Russian jewel is threatened by the industry around its shores. We can only hope that future generations will be able to come here and enjoy Lake Baikal as much as we do.
