Ducks upon the surface of a lake
Of man-made run off
What great ripples they make
Diving under, flapping their wings
Without asking I wonder
Why for ducks water is water
Glacial or sewer-bound
Backswamp or uptown reservoir
It's not maker but mark which matters
So why is this distinction so profound to me?
Why Nature's acts
     Do I endeavour to explain
Whereas for man's
     I seek firstly to lay blame?
