The Kogi Mamos have remained isolated from the rest of the world since the Spanish Conquistadors. In order to preserve their traditional way of life, they rarely interact with the modern world or with outside civilization. Outsiders are not allowed inside their ancestral lands. The Kogi Mamos say that the balance of the earth's ecology has been suffering due to the modern-day devastation of resources by Younger Brother. The Kogi Mamos in turn believe that their work as Elder Brother is instrumental in helping to prolong and protect life on earth.
