World’s water supply and demand

While we constantly worry about getting enough fuel and energy (we’re quite aware of the Peak Oil and other energy crises), the more important matter for most of manking is getting access to clean, potable water.

In developed countries we have clean tap water easily available, and not worry much about getting it. We only worry when we’d like to buy a piece of land with no water mains nor well.

Still, I believe it’s better to reduce water use, recycle it (using greywater systems), harvest and use rainwater, etc. That’s why at the moment the rain gutters in my straw bale house are directed to two 100-liter barrels for harvesting.

Below you’ll find an amazing infographics that summarizes all the important matters regarding watter supply and demand.
