This massive river system is one of the longest in the world and has numerous tributaries that contribute to its flow. The Amazon River basin is known for its rich biodiversity and plays a crucial role in the global climate and hydrological cycles. It supports countless species and Indigenous communities, emphasizing its ecological and cultural importance.
