ABSTRACT
This chapter examines the question of how global practices are constituted and transformed. A practice is a set of activities governed by collectively shared rules. It combines normative views, theoretical knowledge and activities. Practice as a form of life' that connects theoretical knowledge, activities and values is a useful notion for global bioethics. While the ethical problems confronting mainstream bioethics are associated with the power of science and technology, as well as professional power, the problems of global bioethics are related to economic and political power. In global bioethics it is commonly assumed that the best way to influence and change practices is by developing and implementing global standards. Social movements are organizations, groups of people and individuals, who act together to bring about transformation of society'. They use a broad repertoire of activities, from media campaigns to public protest, boycotts, civil disobedience, demonstrations and legal action, but they emphasize non-violence.
