The Panama Isthmus is a narrow strip of land that connects North America and South America. It is approximately 50 miles (80 kilometers) wide at its narrowest point and is bordered by the Caribbean Sea to the north and the Pacific Ocean to the south. This geographical feature is significant for trade and transportation, as it is home to the Panama Canal, which allows ships to pass between the two oceans without having to navigate around the southern tip of South America. The isthmus has a rich biodiversity and is characterized by tropical rainforests, diverse wildlife, and various ecosystems. It plays a crucial role in global shipping and commerce, making it a vital area for international trade. The construction of the Panama Canal in the early 20th century transformed the isthmus into a key maritime route, significantly reducing travel time for ships.
