The major purposes of this study are (1) to examine the significant life experiences on the development of environmental action of three environmental organization female leaders in the Hualien area; and (2) to establish the life paths that those leaders have followed as they have developed environmental action; and to understand how various experiences are individually, socially, politically, and culturally constructed as ‘significant’. The results indicated that those significant life experiences were as follows: “experiences of natural areas (childhood)”, “experiences of natural areas (adulthood)”, “beloved place destruction ”, “worry about environmental problems”, “environmental organizations”, “returning to hometown”, “parents”, “friends”, “participating in environmental organization”, “college club”, “social justice”, “life principles”, and “literature”. Implications for environmental education development in the Hualien area are presented, and recommendations for further significant life experiences research are provided.
