Uncovering Ancient Amazonian Cities: The Secrets of the 'Dark Earth'

Scientists are uncovering the secrets of the Amazon rainforest through the discovery of "Amazonian dark earth" (ADE), a highly fertile soil layer created by ancient indigenous communities. A recent expedition in northwest Bolivia revealed the widespread presence of ADE, which contains ancient artifacts and serves as a potent carbon sink. Businesses are now looking to replicate the methods of indigenous people to produce biochar, a substance that improves soil fertility and helps combat climate change. This ancient knowledge holds valuable lessons for sustainable agriculture and environmental conservation in the face of future challenges.
