In a mad moment once I worked out that there is enough water going over Victoria Falls daily to provide every person on earth with twenty odd litres of water per day. Could someone who cares tell us how many millions of litres of pure water is coming off the hills and going into Milford sounds each day. Unfortunately the water I'm using at the moment is contaminated with ethanol. Maybe someone else with less time to spare could add a few more like
Niagara and the like.
