The first book discusses the seriousness of toxic and electronic waste, the effectiveness of cleanup efforts, and future challenges. The second title examines the global demand for coal power, environmental impacts of burning and mining it, and the future of the industry. In a concise, objective manner, the books investigate historical, economic, political, and environmental issues. Primary-source quotations; short narrative texts, followed by relevant quotations; a section with a bulleted list of one-sentence facts; pertinent illustrations; and annotated lists of key people, organizations, and advocacy groups are included. Opposing quotes are paired off in brackets. These books are well researched and carefully organized, and the discussion and quality content make them useful for research.
