Wednesday, Jan. 22nd - On what basis would you divide our region of study into sub-regions?

Wednesday, Jan. 22nd: We will discuss and do an in-class exercise to deepen and consolidate the 
material covered in the Preface and Chapter 1 of the textbook; before class, do those readings, write 
a response paragraph based on them in which you answer the following question—On what basis 
would you divide our region of study into sub-regions?—and e-mail it to me as an attachment.

Regions of Latin America and the Caribbean

1. Mexico
1. Not really North America, but not really Central America, either
2. Central America
1. Guatemala
2. Belize
3. Honduras
4. El Salvador
5. Nicaragua
6. Costa Rica
7. Panama
3. The Caribbean Islands
1. Northern Islands (Cuba, Puerto Rico, Bahamas, Hispaniola, etc.)
2. Southern Islands (Martinique, Barbados, Guadeloupe, etc.)
4. The Caribbean Nations of Latin America
1. French Guiana
2. Suriname
3. Guyana
5. The Andean Region
1. Northern Section of Chile
2. Bolivia
3. Peru
4. Ecuador
6. The Atlantic Coast
1. Argentina
2. Uruguay
3. Pampas and Patagonia
1. Including Southern Chile, even though it is not on the Atlantic coast.  It seems more similar to Argentina than it does to Northern Chile.
4. Paraguay
1. Again, not on the Coast, but it fits with Argentina - lots of beef, lots of flat land, etc.  
7. Brazil
1. Could also be included in Atlantic Coast, but I gave Brazil its own region due to the language barrier, the economic differences, and the Amazon Rainforest
8. Colombia and Venezuela
1. I really have no idea where these should go.  I thought about including them in “The Caribbean Nations of Latin America,” but they don’t really seem to fit with the other countries located there.
