I thought this story is representing our world. One day, a beautiful nature were destroyed by the construction of buildings. And by that, the clean air started to be polluted. Today, our world is facing a serious air pollution.
I thought that the author is optimist against the upcoming world. It is because in the story at last, the vermints were saved. This is a message to us that we can still save the world. However, it can't be saved by just watching. We all have to cooperate with each other and do everything that we can.
