Baikal contains 80% of Russia’s surface freshwater resources and 20% of the world’s surface fresh water. 800 endemic species live in Baikal. Baikal is more than 20 million years old. Our film is a declaration of love for Baikal. We give an honest and objective analysis of the main issues facing what the locals reverentially call “Saint Sea”. Scientists, ecologists, managers of the Baikal nature reserves and native people discuss the future of the lake in our film. The film does not only talk about Baikal’s problems, but it offers ways of solving them. Baikal’s transcendent beauty, indeed its very existence, depends on us, on every person.
