Pollution fears over world's deepest and oldest lake

The world's deepest and oldest lake, Lake Baikal, is at risk of being removed from the UNESCO World Heritage list. A Russian pulp and paper mill has been polluting the water for decades.

Now, the UNESCO World Heritage Committee is meeting in Brazil to discuss the effect of the plant's waste waters. There are fears the lake may end up on the endangered list or get struck off it altogether.
