How does the setting of the book contribute to the mood of the book and how does the setting contribute to the main conflict?

The Pearl's setting contributes to mood of the book by illustrating the poverty and hardships the villagers face, all while the colonials benefit from their hard work and homeland. Kino's poverty and hopes for his family make the pearl the most important thing in the world. Whereas, the doctor, the priest, and the pearl buyers see the pearl as another way to increase their own wealth at the expense of the poverty they see each and every day.
