One often hear how there is a shortage of water or there will be at some point in the future. A shortage so dire that rationing can occur and all kinds of terrible things will happen just to have water.  Initially, it appears to be a dubious claim.  You may think, how can that be?  The reality is the issue is with potable water.  The earth’s surface is mostly covered in water but  but it’s salty.  In order for it to be usable, this water would have to be desalinated, which is an extremely expensive process.  What would be done with the by-product?

Is conservation the best way?  Is rain water another options?  Is there freshwater available?  Is transport an issue?  I will continue to think about these questions and more as I try to find ways to cut back on on my water consumption.
