With this potential, the Punan Adiu and the organization partners are planning to join the global market of carbon trading. It will enable them to independently fund their conservation programs.
Photosynthesis: plants and other forest organisms use sunlight to synthesize nutrients from carbon dioxide and water. The process removes the carbon dioxide from the atmosphere and generates oxygen as a by-product. When humans destroy nature and release carbon into the atmosphere, the intact forest ecosystem sequesters the carbon and produces oxygen to our planet. Punan Adiu customary forest, 2020.

Piyang and Lukas pose for a portrait in front of a Benggeris tree (Koompassia excelsa) during their forest patrol. The tree grows higher than the average canopy tree and its branch is home for giant honeybees (Apis dorsata). Protected by smoke, local climbers harvest the honey for additional income. With its economic and cultural value, native taboo forbids people cutting the tree down. To protect the forest, the Punan Adiu conduct patrols in their customary forest area. 2020.
