Communication and assessment of scientific information is as important as the science itself, especially when policy-makers, politicians, and media specialists lack scientific backgrounds. Scientific advice has never been in greater demand; nor has it been more contested. This book explores the effect of the public communication of science on the interaction between science and policy development in the regulation of the environment, food, health, and transport sectors. This second "Science and the Law" book by these editors presents a series of case studies that illustrate the impact of science communication to lawmakers and the general public in other areas of policy development, including nutrition, tobacco science, drugs, and environmental issues. The chapter contributors all present an interesting cross-section of current, hot-button issues that revolve around scientific principles, and they clearly demonstrate the extent to which accurate and appropriate communication of science influences leaders and legislation.
