Means "Green Dragon" and refers, on a small, simple scale to my wild, mostly out of control garden. In the garden I can plant things or pull up things, import this fish, or that frog; but then they all decide what they want to do and do it.

In a larger sense it refers to the earth as whole. Whatever you do or change in the world is altered by the world you do it in. The response of the world to our projects is still beyond our ability to predict.
