greed, i think, is just another form of survival. While animals wouldn't know what to do with a bmw, food is definitly high on the list of things to horde. A dog in the manger is a good example, the dog doesn't want the grain but won't let the horse eat it either. territories are as big as can be monitered, regardless of whether the animal needs that much room or not.
And the reason predatory animals don't kill more, is because the best way to protect the food is to eat it, and the stomach can only hold so much.
