Nowadays, many researchers have done researches which bring the miserable situation that the global environment has been facing during the past decades to us human beings, who emphasize that the ecological system will be worse inevitably if we maintain our living behavior. The word Environmentally Displaced Persons (EDP) is used to describe some people whose homeland becomes uninhabitable due to some environmental stressors, for example, the climate change [1]; or describe groups of persons who, for compelling rea sons of sudden or progressive changes in the environment that adversely affect their lives or living conditions, are obliged to leave their habitual homes either temporarily or permanently, and who move either within their country or abroad [2]. There are many researchers identifying some of the island nations being in the dan ger of sea levels rising. It is better for the EDPs to relocate their address to safer places since their homeland is at the risk of being drowned by the ocean. However, there are still many problems they will meet in future, such as being discriminated as refugees losing their own culture heritage, facing with difficulties in being received by groups from different circumstances, and so on. Fortunately, the United Nations High Commission on Refugees (UNHCR) has discovered the dilemma the EDPs may meet. In a recent ruling during the last several years [3], UNHCR has acknowledged that some of the EDPs can be recognized as refugees. There are also many scholars who make presentations to a number of international policymaking fora, helping to raise the profile of these issues and to shape international responses [4]. With receiving much assistance from politicians and scholars all over the world, we are full of confidence that the problem of EDPs will be brought to a satisfactory settlement in the upcoming years.
