Archaeology, Cultural Anthropology, “The Secret of El Dorado”

Rediscovery of ancient "living" soil composting technique, that enabled a civilization of millions to flourish in the infertile upper Amazon, until disease brought by Europeans wiped them out.

Unlocking the secrets, including use of charcoal and plethora of microbes in the soil, will enable farmers to stop burning the rainforest to obtain new farmland that only remains productive for a few years.

An uplifting story that spells hope!
