Patristic interpretation of the results of Adam’s fall for the rest of creation:
But you will say, He [God] Himself is the cause of evil, since He Himself produces the evils through it. What sort, then, are the evils of which you speak? Poisonous serpents and deadly plants, or demons, or any other of those things that can disturb men?—which things would not have been injurious had not man sinned, for which reason death came in. For if man were sinless, the poison of serpents would have no effect, nor the activities of injurious plants, nor would there be the disturbances of demons, nor would man naturally have any other suffering; but losing his immortality on account of his sin, he has become, as I said, capable of every suffering.
