The primary resource found in the Amazon River basin is biodiversity, which includes a vast array of plant and animal species. The basin is home to the largest rainforest in the world, featuring countless organisms, many of which are endemic. This rich biodiversity supports essential ecological services, helps regulate the global climate, and provides resources for indigenous communities and pharmaceuticals. The Amazon is also crucial for carbon storage, making it a vital area for conservation efforts to address climate change and protect the environment.
