Implications of Physical Landscape  Encircled with mountains and oceans, less accessible to outsiders, isolated from the rest of the world  Diverse environments  diverse cultures and economies, large regional differences  Uniting different cultures/regions rather than external expansion is more important

 Limited habitable land  population pressure on the environment  over exploitation of the environment  sustainability  Centrality, ethnocentrism Youqin Huang GOG/EAS 160
