In this video from the movie, The Lorax, it's about giving back to the world and celebrating it. In this movie the Once-ler begins cutting down the troufula trees after his invention becomes a success. After all the warnings from the Lorax that bad things will happen if he continued to cutting down the trees. So in the end all the animals had to go away because all the trees were gone, there was barely any water and because of the the factories that the Once-ler built the air became polluted and it became harder to breathe . But before the The Lorax went away he left the word "UNLESS" carved on a stone meaning unless someone like you cares a whole awful lot, nothing is going to get better. It's not. "The Lorax"
