The life history of Penan ethnic communities in Sarawak is fully dependence on forest resources to sustain their livelihoods. Since from their ancestors, forests provide food sources, medicines, building materials, other equipment and raw materials for making handicraft. The Penan community, are still practicing hunting and harvesting resources from the forests for their daily lives. The Penan relations with the forest are inseparable.

The Penan community in the past lived peacefully and freely using the forest within their customary territories without barriers and restrictions. As a result of forest exploration for logging, Molong's traditional management and practice systems can no longer be practiced by Penans. Once their forest area has been logged, the opening of plantation area for oil palm cultivation has replaced their forest area. The impact of this large-scale farming has led to environmental problems and Penan communties livelihood was also affected. The forests used to be the source of life have now been destroyed and they have to rely on agricultural produce for food, medicines and other daily necessities

The Penan's remote villages located in remote areas, they have no basic facilities such as roads, schools for their education, health clinics, electricity supply and other basic amenities. The absence of these basic facilities makes them difficult to market agricultural produce and sales of other economic products such as handicrafts. Environmental pollution such as rivers and the extinction of forest resources causes health problems, lack of balanced food and their traditional practices are getting lost. The loss of forests has threatened the loss of traditional knowledge as well as loss of identity as Penans.
