Yeah, it may be food for something else, but it could be death or something nearly as bad to a human. Picture this - someone is climbing out of a 2 storey window after visiting his beautiful girlfriend (okay, so the someone is a guy) and he climbs down ledge after ledge, performing feats of acrobatics, then he jumps to the ground, lands and rolls onto his feet. He then hears his g'f's dad shouting at him, threatening him even. So he scrambles into the nearest bush and ooops! slips on that damn banana peel that chai2 through out her car window, hours ago, giving it time to get really mushy and slimy. He slips so hard, he whacks his head on a nearby oak tree that had been planted by his g/f's grandpa in memory of his wife, and he's out cold. Cold-cocked, as it were. His g'f's dad comes around the corner of the garden and sees him. He figures out what happened and, enraged, he goes inside, berates his daughter, and consigns her to a life in the convent.
Now, see what destruction you have wrought?
This could easily have been a Shakespearean play.
