Critical introspection about destruction of global ecology should be concluded ultimately in method searching to ecology restoration and life value realization. In order to this, it is critical matter that we have to recover about human being and regulate status and role of mankind upright. The core distinction of depth ecology and social ecology which represent ecology discussed in western countries lies on cognitive problem about existence of mankind. While depth ecology emphasizes parallel relation between human and nature in the aspect of life community, social ecology put importance that the human are separate special cultural being(the 2nd nature, the 3rd nature)even man kind is natural being. The former rests on the basis of creature-centered ideology but the latter does not go far from human-centered ideology. The pivotal point to be pursued in ecology ideology requires regulation on mankind as cultural begin as well as continuance with nature. Ecological world view of Donghak ideology includes both human as cultural being which lacks depth ecology and social ecology and human as natural being and displays neo-humanism recognition securing worship of heaven-worship of mankind-worship of creature. It understands human and nature as divine creature serving heaven and cognize them not only as organic whole with internal circularity and relation but new mankind, neo-humanism, with ethnical responsibility and summon consciousness to restore life community. In this way, we can plan new methodology in concrete and practical practice about reality of ecological destruction.
