新大陸, or "New World," refers to the lands discovered by Europeans in the late 15th century, primarily the Americas. This term is often associated with the voyages of explorers like 克里斯托弗·哥伦布 (Christopher Columbus), who reached the Caribbean in 1492. The discovery led to significant cultural exchanges, colonization, and the eventual establishment of new nations. The New World includes regions such as 北美洲 (North America) and 南美洲 (South America). It was characterized by diverse indigenous cultures and ecosystems. The arrival of Europeans drastically changed the social, economic, and political landscapes of these areas, leading to both opportunities and conflicts.
