Today, the future of 5,000 ethnic groups and 300 million people is in danger. These populations, considered as minorities, are  victims of genocide. Beyond the threat to their singularity, it is the heritage of all humanity that will suffer severely from their disappearance.

It is to this precious and fragile diversity that Pierre de Vallobreuse's photographic work pays homage. He has traveled for more than twenty years, to all continents, to share the intimacy of twenty-seven ethnic groups. Edgar Morin affirms loud and clear that the representatives "are our fathers, our mothers ... our brothers, our sisters."

This project has given rise to a book, Peuples, prefaced by Edgar Morin, published by Editions Flammarion in 2005, and an exhibition at the Musée de l'Homme in 2005-2006 which then traveled to France and abroad.
