I agree. When California was going through a bad drought, many farmlands ended up being dried up. I have always wondered why they don't install water desalination plants and provide dry farmlands fresh water?
That's easy, states do not want to fund commercial businesses, and farmers have not ponied up to fund water desalination.
If Global Warming and ice cap melt is going to make the seas less saline, wouldn't water redistribution make more sense than dumping fresh water in the ocean? Again... Nah, that takes money and forward thinking.
But... as far as water redistribution goes, 100 years ago States in many cases WITHOUT taxes built watershed systems in the U.S (N.Y started as early as 1910 before income taxes were levied in 1920) and now with horrific taxing districts milking us these same districts somehow cannot even afford to maintain what the ancients built :-)
That said, I see no reason why the government cannot add a few cents to the gas tax and build a water redistribution system... Nah forget it, coffee brewing makers can't even make a coffee pot that doesn't drip all over the place when you pour from it, I guess I should lower my expectations of industry and Government. :-)
