South America is home to some of the world's most famous rivers, including the Amazon River, which is the largest river by discharge volume. The Amazon flows through several countries, including Brazil, Peru, and Colombia, and is known for its vast rainforest and rich biodiversity. This river is crucial for transportation and supports countless species of plants and animals. Another significant river is the Paraná, which runs through Brazil, Paraguay, and Argentina. The Paraná is vital for agriculture and hydroelectric power, with the Iguazu Falls located along its path. Together, these rivers play a key role in the ecology and economy of South America.
