yes, fresh water, and clean water is a growing need.. desalination is one solution
other might include better use of grey water (say the water from your washing maching and sink, (but not the toilet)-- using grey water to water lawns. (again, here is where our exist infrastructure make it harder for most cities/urban areas, to do this.. places with out already existing sewers can build this new technology in..)
but other solutions might include waterless technology for common things.. water is great for washing cloths.. but is there a better way? maybe sonic waves.. or super absorbient matterials to absorb body oils from clothes..
or just change to front loading washers.. (so maybe investing in Maytag will be just as effective)
the earth is over 70% water, but only about 4% of it is fresh water at any given time! thank goodness the earth is already adapt at recycling salt water into fresh!
