The largest river in the world by discharge volume is the Amazon River. Originating in Peru, it flows through several countries, including Brazil, where it ultimately empties into the Atlantic Ocean. Known for its vast network of waterways and profound ecological diversity, the Amazon River basin is home to numerous species of plants and animals, many of which are unique to the region. The river is crucial for transportation, local economies, and the cultural practices of the indigenous peoples who inhabit its banks.
