The Cerekang Indigenous People have a completely modern day-to-day life. However, their belief in myths has proven to be a fortification of environmental sustainability. Myths gives a clear boundaries for every member of the community and the outsiders about what is allowed and what is forbidden. Using a descriptive qualitative method with a participatory approach, this research will answer two things: First, how do the myths in the Cerekang Indigenous people work to preserve the forest? Second, how does this myth survive the changing times? This study states that myths can be used to solve environmental problems in this modern era, because environmental problems are not only physical problems but also social and cultural problems. Myths work in the form of mystical narratives that are believed by local communities to protect forest areas from internal and external disturbances, which if violated will have unimaginable consequences. This myth is still alive and is believed from generation to generation as something sacred in society. Although it must be acknowledged that this cultural and ecological heritage remains vulnerable to social change in the future.
