The Lake Baikal is the deepest freshwater lake of the planet and the largest reservoir                     of fresh surface water. Its famous clear waters host a great diversity of flora                     and fauna.                     This lake is located in Asia and is part of the territory of Siberia                     in Russia in the boundary of the Russian provinces of Buryat Republic and Irkutskaya,                     near Irkutsk city. The Baikal Lake is considered by CEDAM one of the seven underwater                     Wonders of the World. The name Baikal, derives from two words of the Turk language,                     “bai” that means “wealthy” and “kul” that means “lake”.
                     The maximum width of the lake is 79.5 kilometers, its width minimum is 25 kilometers                     and it width medium is 47.8 kilometers. The lake lies along a tectonic break, which                     explains its great depth. The maximum deep of the lake is 1637 meters, which make                     this lake the deepest of the world, nevertheless its average deep is 758 meters.                     The Lake covers an area of 31722 square kilometers. Around 330 rivers flow their                     waters into this lake, being the most important the Selenga, Upper Angara and Barguzin                     rivers. Inside the lake there are also 22 islands, the largest island is Olkhon.                     It calculates that the lake contains around 23 615.390 cubical kilometers of fresh                     water almost 20% of the world surface fresh water reserves. It contains more water                     than all the North American Great Lakes combined. It is also the oldest lake of                     the world; since, this lake has existed since 25 million years ago.
                     One of the main features of the Baikal Lake is the clearness of its waters; the                     water is so clear that any object can be seen well at the depth of 40 meters. Besides,                     Baikal Lake is one of the most beautiful lakes of the planet and it is one of the                     few lakes that is still growing; the lake grows with an average speed of 2 cm per                     year (0.8 inches).
                     The lake hosts an impressive unique flora and fauna. Scientists have identified                     about 2600 species of animals and plants and almost 70 per cent of them are endemic                     that means, they only can be found in this lake. One of the most representative                     inhabitants of the Baikal’s ecosystem is the Nerpa (Phoca sibirica), a unique freshwater                     seal which lives in the northern zone of Baikal and in the Ushkanye islands. Another                     symbol of the Baikal’s fauna is the Omul, the most popular salmonid fish of the                     lake. Other representative specie of the lake is the Golomyanka also known as Baikal                     oil fish, an unusual beautiful fish, which is a translucent fish that live in depths                     between 200 and 500 meters, this kind of fish is famous for disintegrating and become                     a mass of oil and bones when they are exposed to sunlight. The region is inhabited                     also by foxes, eagles, deer, bears, and many others animals and plants.
                     The lake itself is a true wonder; but, besides it is surrounded by a marvelous landscape                     composed by rocky mountains and beautiful forests; therefore is one of the favorite                     places in Russia to do activities such as trekking, camping, kayaking, biking, fishing,                     etc.
                     About the Lake Baikal, the famous Russian writer Anton Chekhov said: "Baikal is                     amazing, and it is not without reason that Siberians refer to it not as a lake,                     but as a sea. Its water is unusually transparent, so that one can look though it                     as through air; its color is a soft-turquoise, pleasant to the eye. Its shores are                     mountainous and forest-covered; impenetrable wilderness all around. A profusion                     of bears, sable, wild goat and all sorts of wild thing".

History
                     Since ancient times many people had been living near Lake Baikal.                     There are vestiges                     of human presence in the region that date from the Stone Age, the first inhabitants                     of the region, considered the lake a sacred place, therefore Lake Baikal was known                     as Sacred Water or Sacred Sea and the people prayed and believed in the lake’s power.                     But, the major migration of people to the Lake Baikal’s region occurred after the                     Russian discovery of the lake in the XVII century. In 1643, the Cossack Kurbat Ivanov                     was the first Russian that arrived to the eastern Siberian. In 1647 Vasily Kolesnikov                     led an expedition that reached the Baikal’s northern coast.
                     Since the beginning, the Russian people developed an economy integrated to the lake,                     which was based in the fishing, nut gathering and hunting that means Lake  Baikal                     has been the base of the region’s economy.                 
                     Since its discovery, many expeditions explored the Baikal Lake, one of the first                     was the scientific expedition sent by Peter I in 1723. In that time most scientific                     works about the lake were published by the Saint Petersburg Academy. However, only                     in the XIX century because of the construction of the Trans- Siberian Railway; systematic                     geographical and geological explorations were realized in the Baikal Lake. During                     the XX century, many other researches were done in the lake including a complete                     exploration organized by the Academy of Sciences. In 1976, the first satellite photography                     of Baikal Lake was taken. Nevertheless, despite all the expeditions and the long                     time that the lake has been explored, many questions and mysteries about Baikal                     Lake still keep.
                     The Baikal Lake was declared World Heritage by UNESCO in 1996. Unfortunately in                     the 50 last years, the creation of many civil and industrial settlements has generated                     devastating pollution in the “Sacred Water”, generating a terrible impact in the                     delicate ecosystem of the Baikal Lake. The garbage, chemical waste derived from                     the agriculture and the growing of stream of tourists as well as the creation of                     pulp and paper plants are damaging the largest fresh water reservoir of the Earth.
                     Because of the growing contamination, authorities are taken some measures to protect                     the lake; such as, forbidden the logging of timber and the timber’s transportation                     over the Baikal Lake. Several industries in the Buryat Republic have been converted                     to close cycle water system to stop the contamination and the population around                     the lake is educated in order to protect the natural environment. But, these politics                     are insufficient to combat against the threat over the Baikal Lake. Currently the                     two main pollution menaces are the Ulan- Ude town and the Baikal’s Pulp and Paper                     Factory.
                     The future of this wonder of the nature depends now of the decisions of our generation.                     It is our responsibility fighting for the preservation of places like the wonderful                     Lake Baikal.
