From the hilltop,
  one can watch nature reclaim:
 green grows up the glass,
 tufts sprout from each crevice
  and the man-made world is crevice-laden,
 one seed blown into a mortar crack
  will become a wedge -- 
   a sprout that splits stone. 

Concrete and steel prove
  digestible:
  time, water, oxygen,
 the enzymatic requirements are few.

Fungi blooms from a pile-full of dung. 

I don't know whether it's a desirable meal,
  whether our trappings & vestiges are 
  haute cuisine, 
   or merely a meal 
   of convenience.

This place was once with us.
 Now, it's hidden so well
  that it's become a myth,
 a once firm and tangible thing --
  now invisible & conceptual.

Nature swallowed our world
 and farted our mythos.
