The story taught us how important it is for us to protect the environment. First there was green everywhere, and this little creatures were having a good time wandering around. But one day the big creatures came and build so many buildings, and made the whole place with almost no green. Though in our world we still have green, but by watching the video it made me think that maybe our world will be like this too soon in the future.
In the end, the big creatures started to suffer living, and it looked like the little creatures who tried to keep green were saved by a jelly-fish-like-flying-in-the-air. I think the big creatures were being punished for hurting the planet they live on, and the little creatures were sent away somewhere else to get a second chance to live with green.
