Social Work in a Sustainable World addresses the context of social work and the responsibility of the social worker within the larger global community. Mary extracts the fundamental principles of various schools of thought to clearly demonstrate the need for change in the way social workers view their immediate communities, the global community, and their responsibility to each. With sustainability and its dimensions of human survival, biological diversity, and equity as key concepts, Mary urges social workers to act as agents of change and to take on new challenges and roles in the institutions of politics, the economy, the environment, and, ultimately, social welfare.
