Unless

The message that Dr Seuss is giving to the readers in the Lorax is about our responsibility. The Once-ler did not care for the environment because he did not care that the Bar-ba-loots were hungry because the trees were cut down. The Swoome- Swans could not sing because of the smokes from the factory and he did not care that he was putting oil in the pond where the Humming-Fish swam in. The thing that the Once-ler was only interested was money. So the Lorax had enough. He went somewhere else to live. All the animal went somewhere else to find food and a place to live. The Once-ler caused lots of conflict with the animals and environment.The Lorax was the king of the trees. Unless I will keep the universe tidy for the next generation it won't be a untidy world to live in.
