Summary of clip: Ted Wiggins has the last tree seed. He needs to get it to the center of town to plant it in front of the townspeople of Thneedville. He is chased by Mr. O'Hare, the town businessman and owner of O'Hare air, which bottles and sells air to a town with no trees. He is trying to prevent Ted from showing the town the seed. With the help of his friend Audrey and his Grammy, Ted wins the race for the seed and breaks downs the wall of the city to show everyone in town that things are not perfect outside of Thneedville. They convince the townspeople that planting real trees will allow photosynthesis to occur and will result in free, fresh air.
