Middle and South America: Review and Self-Test
1. Environment: Deforestation in this region contributes significantly to global climate change through the removal of trees, which as living plants naturally absorb carbon dioxide, a greenhouse gas. Once the trees are cut or burned, they release large amounts of carbon dioxide into the atmosphere. Additionally, despite the region’s overall abundant water resources, some areas are experiencing a water crisis related to climate change, inadequate water infrastructure, and intensified use of water.

2. Globalization and Development: The integration of this region with the global economy has left it with the widest gap between rich and poor in the world. Long-term failures to address poverty, economic instability, and the flow of resources and money out of the region have resulted in many conflicts and inspired numerous efforts at reform. Nevertheless, in recent years several countries in this region have emerged as global economic leaders.
