Blue water pours freely under the sun, white water rushes with gravity, grey water is polluted by human use, black water is water that could be there, according to the capacity of the land, and may be some day, but green water is a flow that passes through the living world and so, although flowing, is still.

A blue lake or river can’t do that, but a green one, which is both river and lake, can.

Look at those green waves of time!
