The natural environment of Gulup-do should be preserved due to its unique ecological characteristics. A recent report stated that CJ group, one of Korea’s major business conglomerates (chaebols), plans to construct golf courses and resort facilities in Gulup-do. Such projects will destroy the delicate animal habitats of the island. The harmful chemical runoff from golf courses will also significantly damage the ecosystem. The purpose of this paper is to show that the development of Gulup-do will adversely affect the ecology of the island.
