Most controversies in environmental policy are rooted in clashes of values involving science and technology versus humanism, economic efficiency versus humanism, the role of nature in society and the role of government in society. The author discusses how America makes environmental policy - at the Federal and State levels as well as their enforcement agencies designed to protect and regulate at the same time. Portney examines legislation, public opinion, implementation or non-implementation relative to the debates over water, air and soil management.
