In the climax, the Once-ler (voiced by Ed Helms) realizes the consequences of his actions and the harm he has caused to the environment. He decides to give the last Truffula seed to Ted (voiced by Zac Efron), the young protagonist, and encourages him to plant it to bring back the Truffula Trees.
In the resolution, Ted returns to Thneedville and, with the help of his friends, including Audrey (voiced by Taylor Swift), he confronts the villainous Mayor Aloysius O’Hare (voiced by Rob Riggle), who has been profiting from the scarcity of trees. The townspeople, inspired by the story of the Lorax, turn against the mayor.
Ted plants the Truffula seed, and with the assistance of the magical properties of the seed, the town begins to transform. The film ends on a hopeful note, suggesting the potential for nature to be restored and people to live in harmony with the environment.
“The Lorax” promotes environmental awareness and conservation, and its ending reflects the importance of taking responsibility for one’s actions and working towards positive change.
