I just read this news off Washington Post, and it absolutely blew my mind! This shows just how complex our ecology is and how little humans understand our environment.

I particularly love the last comment by Thomas Bigford, on how engineering happens at all sorts of different scales and levels. Imagine the tiniest critter linked to the biggest creature through a complicated web of dependency. I think James Cameron got the Avatar idea spot on!
