Generalist Social Work Practice provides students with the foundational skills and knowledge needed to serve clients across micro, mezzo and macro areas of practice. Author Janice Gasker brings a focus on self-reflection as the first stage in the planned change process and writes with the perspective that we consider work at all levels of practice simultaneously rather than in isolation. Fossil fuels (coal, oil, gas) have, and continue to, play a dominant role in global energy systems. But they also come with several negative impacts. When burned they produce carbon dioxide (CO 2) and are the largest driver of global climate change. Key idea. Specification content.
