Light pollution annoys me on several levels.  The energy wasted is one, but the bigger one is the masking of the moon and stars.  We all miss the patterns in the sky and the comforting travelling they slowly make day and night.  About a quarter of a mile away there is a house that permanently seems to have a million billion watt flood light on.  I am unsure of its purpose.  Maybe they believe that it gives them some sort of security?  Or maybe they have some pets/livestock that are afraid of the dark?

The image above is a spectacular picture taken from the ISS.  Pollution or not, it is amazing.  You can pick out towns and villages and the arteries that connect them.  And I think I can see my neighbour’s yard?
