On the surface of the planet only % of water is freshwater in the forms of lakes and streams.

Ideas to reduce water stress in preparation for the anticipated shortages include:
→ pollution in rivers and lakes
→ using water conserving technology
→ perfecting desalination plants to process undrinkable water into drinkable fresh water
