The importance of coexistence between humans and nature is being enlarged more than before in the 21st century. Some areas are not developed entirely, whereas other regions are megalopolises. This lets us deeply think about what is essential to humanity. In this session, we would like to contribute to the Asian-Pacific region's peace and prosperity by proposing international cooperation to recognize and conserve potential world natural heritage sites (volcanoes and marine environments, etc.) that have outstanding universal values in Asian-Pacific regions.
