Fast of all, the scene at the very beginning of the movie reminded me of the opening ceremony of the London Olympic; the scene of the industrial revolution. Lots and lots of labors build dirty gray buildings and factories, and beautiful nature was completely destroyed. I thought the same thing was depicted in the movie. Anyway, the creator might want to say that we have to stop destroying. I think it was about destruction leaded by human's selfish endless exploitation. However, something (looked like jerry fish) that save us was also depicted in the movie. It was created by the main character. He tried to keep fragment of the beautiful nature of the past (branch) and finally it brought them back to bright place like the past. I thought the creator also want to tell that each of us must not take this terrible sad trend for granted and obey (to destroy of our own accord was the worst...), but must do something to bring the beautiful nature back and we can do it.
