The Clean Air Act of 1970 set out for the United States a basic, yet ambitious, objective to reduce pollution to levels that protect health and welfare. The Act set out state and federal regulations to limit emissions and the Environmental Protection Agency was established to help enforce the regulations. The Act has since had several amendments, notably in 1977 and 1990, and has successfully helped to increase air quality. This book reviews the history of the Clean Air Act of 1970 including the political, business, and scientific elements that went into establishing the Act, emphasizing the importance that scientific evidence played in shaping policy. The analysis then extends to examine the effects of the Act over the past forty years including the Environmental Protection Agency's evolving role and the role of states and industry in shaping and implementing policy. Finally, the book offers best practices to guide allocation of respective government and industry roles to guide sustainable development. The history and analysis of the Clean Air Act presented in this book illustrates the centrality of scientific analysis and technological capacity in driving environmental policy development. It would be useful for policy makers, environmental scientists, and anyone interested in gaining a clearer understand of the interaction of science and policy.

As the values of integrative medicine continues to grow, alternative points of view and treatments are increasing in acceptance and prevalence. Homeopathic medicine is considered an important root to this approach. However, contributions of homeopathically qualified doctors have long been overlooked. A Century of Homeopaths is a detailed account of the many homeopaths who have contributed to medical progress since 1840. The accomplishments of over 100 homeopaths form the organizing structure of the book - many of whom have been lost to history. The text describes the ways in which homeopaths have influenced medical practice, research and public health, as well as the seminal effect of homeopaths in the emergence of today's medical specialties and in social reform, thus providing insights to healthcare professionals, researchers, students and medical historians.
