I watched a short movie "mirage".
A robot like human beings stored water in his stomach. He ran around looking for water.And finally, he found a thing like a ball containing water and took water. However, a fish were dying by being taken water. So he put a fish in his stomach and saved a fish.
I think a robot represents human beings. Human beings take things which they want by force and this movie warns that many creature have suffering from our arrogant act. So we should think of the environment.
