A vital element for our survival. There is a lot of it yet not enough.
For some, it is captured in a lake and the lack of it means big trouble.
For others, it makes for a nice view..
Sometimes, it is there to drive the price of property up
In some places, it is used for decoration
And in others for recreation
It has been used for sailing, for trade and it has opened up the door into the world. It has caused wealth, it has caused misery, it could cause prosperity and it could cause war and conflict.
It is very important and yet underappreciated.
