The notions of global (international) security and risk have not been defined precisely and uniformly enough thus far, primarily because they involve threats and opportunities that have not been fully realized. Until recently, international security was considered synonymous with military security, although it is clear that this is an inadequate definition. There are in fact at least eight different types of human security, namely, economic, food, health, environmental, personal, community, political and natural resource. The threats to security are also varied and can be military, economic, social, or ecological.
