本論文試圖從漢斯?尤納斯的存有論倫理學理論，討論其對環境倫理的道德奠基。預期成果是透過漢斯?尤納斯的存有論倫理學，突顯環境危機受到科學技術影響特色，並因其受到技術此一後果不可逆、難以預測的巨大行動，來要求一個新的倫理型態，而這個倫理的最終義務是要求環境與未來人類世代的永續。並且最終思考環境倫理學在尋求人類對自然的最終義務之時是否須要存有論奠基。 The ethics with ontology of Hans Jonas is involved the basic obligation of environmental ethics. With his theory, I will try to exhibit how his though in the thesis indicates the characters of technological results. As far as the immenseness of technological force, a new type of ethics will be required in Technological Modern Century. And the new ethics will point out the ultimate duty which belongs to human being. It means how people treat our environment by preventive way.
