His missions in the Amazonian rain-forest (see map at right) in close contact with the "People of Nature", the Índios gave him a new conception of Man-Nature interaction.
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.

This association allowed him to fight for the transformation of the Amazonian biodiversity and medicinal plants into a truly genuine pharmacology benefiting both Amazonia and the Western world.

Thus, from 1992 Prof. Dr. Meyer participated as an official member of the State of Amazonas delegation in the UN Earth Summit Rio 92.
It is in this context that, in 1994, he coordinated on Brazilian territory – after a due hand-over by the French Ambassador in Brasília – the first Ministerial "mission for biotechnology to valorize biodiversity" ever to be organized between France and the State of Amazonas.

This mission, which had been initiated in 1993 by the French Minister of Research and Space Hubert Curien (via the National Program of Bio-technologies, directed by Prof. Dr. Daniel Thomas), was carried out under the auspices of the French Ministry of Foreign Affairs, with the active involvement of the Governor of the State of Amazonas.

In 1994, Meyer appeared as a special delegate from Brazil to the UNESCO's World Symposium on Literacy in order to present his new approach merging linguistic abilities and biodiversity know how.

In 1999, Dr. Meyer was appointed by UNESCO to write a report on the means to consider in order to establish a "bridge of equitable communication and cooperation" between the Amazonian Amerindians and their traditional knowledge, on the one hand, and the Western world and its modern Culture, on the other hand.
The bottom line was to set up the appropriate tools and create the necessary procedures for such a cooperation to be made possible, taking into account the specificity of cultural diversity, the way both these cultures function, and the pragmatic instruments of cooperation.

Since then, he has gone on to found PISAD: Programme International de Sauvegarde de l'Amazônia, Mata Atlântica et des Amérindiens pour le Développement Durable [International Program to Safeguard Amazonia, the Mata Atlântica and the Amerindians for Sustainable Development], a humanist and non-profit organization.
To implement it, he has created a "platform of fair and equitable dialogue – a bridge – between preserved Índios and western scientists" to valorize  the ancestral knowledge of the Índios and the Amazonian biodiversity.
Originally, Meyer set up an operational concept and methodology regarding the psycho-cultural revitalization of  endangered Amerindian knowledge which he had pioneered as Cogni'Índios.
