Abstract: The field investigation,taking the village in Chollanamdo of Korea as subject,exposed the double disasters caused by ecology and social culture in the 1960s when the urbanization was upgraded and the green revolution in agriculture invaded the village to cause the worm sacrifice ceremony to disappear.The investigation aimed at warning that the technical introduction could not only be judged by whether it is labeled with “science” or not,instead,we should see whether it is in harmony with local cultural community and ecological system.Standing in a position of cultural opposition,the author proposed the “proper technology concept” as the base for evaluating technical improvement in eco-anthropology.

Key words: ecological balance, proper technology, community culture, worm sacrif
