"We Come from the Earth, We return to the Earth, In Between We Garden." - Anonymous

What a wonderful sentiment.  If only more of us practiced gardening the world would be a much saner place.  Or would it?  We in the spoiled Western World would probably benefit with more gardeners and less consumers of finite resources.  Plenty of people are forced to garden, in developing nations, just to survive.  I wonder what they would make of the above saying.  It is like the old saying "What's good for the Goose is not necessarily good for the Gander" at least, that is my take on it. 
Just the same I still think gardening is good for you.  You plant things and you know you only have so much control over what they develop into.  Success is sweeter when you  manage to harvest something - especially when you know that all you did was plant it, water it, fertilise it and then wait and see what nature brings to the table.
