Water woes…

Why are we investing so heavily on corn ethanol? So that we can have cheap fuel.
Why do we want cheap fuel? So that we can drive to Wal-Mart twice a week instead of once in our fuel inefficient vehicles.
Good grief…
Would it not make more sense just to conserve gasoline while investing in truly sustainable energy sources? You know the ones that don’t suck freshwater or natural gas, as corn does.
I don’t get it! Why isn’t responsible driving a conservation practice?
