Water?

They way we use water is never going to be sustainable. Until we start either reusing water or converting sea water to clean water.Water will be sold when their are no viable water sources that wont cost a fortune.We should start recycling water and using sea water to make it into clean water. In New Mexico we have droughts so we have restrictions on water use, but other regions they just use water up so i think that we should have a plan that if our main water source is unusable we should have a back up that will sustain us for weeks at a time.
