Yes, on Oct 31st, 2011 there will be a population of 7 billion human water users in the world. The UN suggests that each person needs 20-50 liters of safe water for drinking and sanitation, per day.
Doing that math for 20 liters/pp/day = 140 billion liters of water needed each day in the world for drinking and sanitation.
To put that in perspective, as you watch the 2012 Summer Olympic's aquatic events, you will now know it would take the equivalent of at least 14,000 London Aquatics Centres worth of safe water each day, for humanity.
The Blue Ecology vision discussed on this blog is a means towards sustainable survival, with dignity.
