Okay, I've got a scenario for you.  Nature comes along and produces a 
super-cow.  We are talking a veritable lawn-mower of herbivores.  Grows 10 
feet tall, weighs a few tons...elephant sized here.  It could possibly 
solve the third world's protein and dairy problem forever.  But it only 
likes to eat a certain kind of plant.  In fact, it eats all of these 
plants. The super-cows, even though they are bovine stupid, have changed 
the environment.  They have caused the extinction of another specie.  

Is the cow guilty.  It couldn't reason that it was killing off all of 
plant "A", but it did it anyway.  

Evolution kicks some species to the curb.  Weather shifts kick some 
species to the curb.  The shifting of tectonic plates have caused more 
extinctions through the ages than one would dream about.  And lets not 
forget disease.  Man is not very efficient at extinction, it should take 
lessons from nature.
