How is the second ghost different from the first ghost in a Christmas carol?

In "A Christmas Carol," the second ghost, the Ghost of Christmas Present, is vibrant and jolly, representing abundance and generosity, in stark contrast to the first ghost, the Ghost of Christmas Past, who is somber and reflective, embodying memory and nostalgia. While the first ghost focuses on Scrooge's earlier life and the events that shaped him, the second ghost showcases the current joys and struggles of people around him, highlighting themes of compassion and community. Additionally, the Ghost of Christmas Present is accompanied by a sense of urgency, urging Scrooge to recognize the importance of the present moment and the impact of his actions on others.
