Thneedville (from "The Lorax" 2012 movie): A Dystopia

                                                                                                                                      
 Thneedville is a walled city that, aside from the citizens, is completely artificial, where everything is made of plastic, metal, or synthetics.  This city is completely closed off to the rest of the world; citizens aren't allowed to leave.  Why?  Because the land around is a complete wasteland due to the complete deforestation and devouring of the land in order to create Thneedville.  If people left the city, they would realize the corruptness of the town's leaders (specifically the mayor).  This is an example of a dystopia. The people have been completely brainwashed into believing that they live in a healthy environment; they have no idea about the concept of nature, natural resources, or how bad their artificial environment and lifestyle is.  Of course, the plot changes as the story ends and Thneedville breaks free of it's plastic lifestyle, but as for the majority of the movie, Thneedville is the perfect example of a dystopia; the plot of the story depends on it.
This song represents how oblivious the people are to their world, as well as introducing the plot/beginning of the story.
This could possibly be a good clip to play for the class.
