Claim: Swiss-Brazilian Doctor Meyer's missions in the Amazonian rain-forest, wherein he was in close contact with the "People of Nature" or the Índios, lead him to combine his expertise in neuro-psychology in the field of linguistic and cultural diversity, with his experience in biological diversity, and its preservation by bio-technologies.
Evidence: Mario Christian Meyer is a Swiss-Brazilian doctor and advocate for the sustainable development of the Amazonia and preservation of its indigenous cultural heritage. This official mission led him into the heart of the Amazonian rain-forest for the first time, where he undertook an exhaustive case study about the different forms of graphic representations of the written language used by the Amerindians in their pictographs, ideograms, petroglyphs and body paintings (e.g. Genipapo – Genipa americana, Urucu – Bixa orellana), obtained using plant pigments, where he discovered the power of their active ingredients. They lead him to combine his expertise in neuro-psychology in the field of linguistic and cultural diversity with his experience in biological diversity and its preservation by bio-technologies.
