Trophic Cascades

        

  

While this doesn't necessarily comprise core information in Greener Gardens, I have found the concept intriguing and applicable over many different scenarios.  Can you think of other trophic cascades?  

The only point I quibble with is the idea of that a trophic cascade tumbles from the 'top to the bottom.'  Such human-centric thinking often leads us down destructive paths. Because bacteria can decompose human corpses, if they had written the theory, they would have been at the 'top' not us. 

'Top' is a construct.  Not an actual place.
