The robin and the fox

Long ago, when no machinery was in this world, there lived a bright, cheerful, forest. But Felia, a keen fox, always distured other animals.
One morning, Felia went to Ron the robin's tree. She scratched on the bark, destroying the tree. "Don't do that!" Ron cried, "you are destroying my tree!"
But Felia would not stop. Then she stopped. She gave a sly smile as she saw what she did to the tree. It was torn, and was wobbling unsteadily. And that is what Felia loved to do. Destroy. And Felia did that to every tree she saw. That is why we are running out of trees.
