The rivers of South America are vital for the continent's ecology and economy. The most significant river is the Amazon River, which is the largest by discharge volume and flows through several countries, including Brazil, Peru, and Colombia. Other important rivers include the Paraná and Orinoco, which support diverse wildlife and provide water for agriculture and transportation. These rivers also play a crucial role in the lives of millions of people. Many communities rely on them for fishing, drinking water, and irrigation. Additionally, the rivers are essential for trade, connecting remote areas to larger markets and facilitating the movement of goods across the continent.
