If the rest of the planet’s fresh water
disappeared, there would be enough left in Lake Baikal, Russia
to supply humanity for 50 years. It is world's oldest (25
million years old) and deepest (over a mile deep) freshwater
lake and contains about 23% of the world's fresh surface water.
In Mongolian it means "the Nature Lake." Appears the screams
about running out of fresh water are a bit premature.
