It works to foster the harmonious integration of people and nature for sustainable development through participatory dialogue, knowledge sharing, poverty reduction, human well-being improvements, respect for cultural values and by improving society's ability to cope with ...

Protected areas with multiple coterminous or overlapping designations (e.g. Northeast Greenland National Park and the corresponding Biosphere Reserve) are listed only once. Currently, Marae Moana is the largest protected area in the world with a total area larger than Mexico (1,964,375 km 2).
Biosphere 2. Closed ecological systems or contained ecological systems (CES) are ecosystems that do not rely on matter exchange with any part outside the system. The term is most often used to describe small, man-made ecosystems. Such systems can potentially serve as a life-support system or space habitats. [1]
A view of the Earth's ecosphere. An ecosphere is a planetary contained ecological system. In this global ecosystem, the various forms of energy and matter that constitute a given planet interact on a continual basis. The forces of the four Fundamental interactions cause the various forms of matter to settle into identifiable layers. These ...
