<P> Soon the once beautiful area becomes choked with pollution and as the Once - ler is trying to find out how his company is doing in the Scandinavian market (by this point Thneeds, Inc. has expanded outside the USA), the Lorax comes into the Once - Ler's office to protest that the Brown Bar - ba - loots, which fed on Truffula fruits, are nearing starvation . The Lorax starts sending the fauna off to more hospitable habitats . After this, the Once - ler's conscience tells him he is doing a lot of bad things, to which the Once - ler responds, "But if I didn't do them, then someone else would ." When his conscience agrees, the Once - ler says progress has to get bigger . As the Once - ler is thinking about how successful Thneeds are selling all over the country, the Lorax protests that the "smogulous smoke" fills the Swomee Swans' throats with smog, preventing them from singing . Finally, the pond that was home to the Humming Fish is filled with toxic waste called "Gluppity - Glupp" and "Schloppity - Schlopp" that clogs their gills .) Confronted by the Lorax, the Once - ler appears to be ready to listen, until his secretary explains that the company's stock report has come in, and' Thneeds, Inc' is doing exceptionally well . The Once - ler then scoffs at the Lorax, claiming that he will keep on making Thneeds, regardless of the consequences . As he finishes his taunt, the sound of an ax is heard, and the two are witnessed to the leveling of the last Truffula tree . With no more trees, the factory shuts down, and the Once - ler's relatives pack up and leave . The Lorax sadly glances at the Once - ler, before he lifts him by the seat of his pants, and disappearing through a hole in the smog . On the spot where the Lorax last stood, sits a small pile of rocks, with a word carved into one: "Unless ." </P> <P> The tale then switches back to the Once - ler talking to the boy, who is given the last Truffula seed by the Once - ler, encouraging the boy to help revitalize the long - dead trees by growing a brand new forest, with the possibility that the Lorax and all of his friends may then come back . The camera shows us a larger hole in the smog, which is the background image to the end credits . </P> <Ul> <Li> Eddie Albert - Narrator </Li> <Li> Bob Holt - The Lorax, Mr. Once - Ler </Li> <Li> Athena Lorde - Ms. Funce - ler, </Li> <Li> Harlen Carraher - Humming Fish </Li> <Li> Thurl Ravenscroft - Singer </Li> <Li> Matt Bennison - Ted </Li> </Ul> <Li> Eddie Albert - Narrator </Li>
