Latin America has diverse physical and human geographies influenced by natural hazards and the Andes Mountains. The Andes create distinct altitudinal zones from tropical to alpine areas that have influenced settlement and culture. Countries exhibit a range of human development levels based on metrics like income, education, and life expectancy. International issues in the region include cross-border drug trade, migration patterns influenced by economic disparities, and changing dynamics along the US-Mexico border as border security has tightened in recent decades.
