Miami, Florida is the financial capital of Latin America despite having no natural harbor, no bedrock, and some of the most vulnerable geography in America. How did this city become one of the most important economic hubs in the Western Hemisphere? Miami was built on six feet of porous limestone at the edge of the Everglades. Geography gave it almost every disadvantage imaginable: No deep harbor. No major river. No solid ground. Yet today Miami controls enormous flows of Latin American wealth, trade, finance, and migration. In this video, we explore how a railroad, the Cuban Revolution, and decades of political and economic crises across Latin America transformed a subtropical swamp into a global city—and why the same geography that should have stopped Miami may now threaten its future. 00:00 — Why Miami Shouldn’t Exist 01:06 — Why Nobody Wanted to Build Miami 02:06 — The Railroad That Created Miami 02:47 — How the Cuban Revolution Changed Miami 03:24 — Why Miami Became Latin America’s Financial Capital 05:27 — The Geography Problem Under Miami 06:35 — Why Sea Level Rise Is Different in Miami 07:32 — Miami’s Billion-Dollar Flooding Problem 09:11 — Why People Keep Moving to Miami 11:21 — Can Miami Survive Its Geography? == Geography Effect explores how geography shapes the world around us.
