Your wish is granted, but the animals became fed up with humans attacking them, so they began to attack the human race. Also, the Ents decide that they have sat watching humans kill their trees long enough, and they come and attack. They do what they did to Isengard to every major city in the world. Congratulations! THe human race has now been eradicated.
I wish that people would post good reviews (that means no spam, flames, or insults) to my fan-fictions.
