The Congo Basin is a large area in Central Africa, primarily located in the countries of Democratic Republic of the Congo, Republic of the Congo, Cameroon, Central African Republic, Gabon, and Equatorial Guinea. It is home to the second-largest rainforest in the world, which plays a crucial role in regulating the Earth's climate and supporting biodiversity. The basin is drained by the Congo River, one of the longest rivers in the world. This region is rich in natural resources, including timber, minerals, and wildlife, making it vital for both local communities and global ecosystems.
