    Sorry, when reading recyclebank exercises, question keep popping up in my head...

    I don't understand how we can run out of water on the earth. All the water on the earth never disappears, if i am correct, stay within our atmosphere. If pure water can be extracted from waste water via evaporation and/or distillation, and water treatment, how can we have a shortage? I guess if some of the earth's water is displaced, drinking water, with sludge sitting in it, then evaporation/distillation? I learned through recycle bank that a small portion of water on this earth is drinking water compared to the vast majority, ocean water.

    Or evaporation from some dioxin-water-pit, the water evaporated would be chemical free.

    Can't large scale distillation draw out water from the chemical water slush to extract "pure water?"
