Explain how the value of oil exports in Tunisia has changed during the 21st century. What else can you infer about Tunisia, its economy, and the human and physical geography impact of Tunisia’s oil industry based on this information and what you have learned from the chapter?

Tunisia’s natural resources are relatively meagre. Until the discovery of petroleum, the principal mineral resource was phosphate; of this, one-third is exported, and the remainder is used by domestic chemical industries. Fertilizer is also an important export. Other major mineral resources are zinc, lead, barite, and iron.
