The reader should understand how environmental issues can be regulated by law and politics, and how environmental ethics can contribute to this task; why political-legal regulation is needed; the principles of political–legal measures; and the instruments that regulate environmental behaviour. This chapter aims to understand what defines environmental politics and law and what are their goals and responsibilities. It describes the different areas and issues for which environmental law is responsible. The chapter discusses generally the contribution of environmental ethics to the task of regulation of environmental questions by the state. Political–legal regulation or environmental law is an important tool for the protection of the environment in accordance with economics and social life. It is a complex and interlocking body of statutes, common law, treaties, conventions, regulations and policies that, very broadly, operate to regulate the interaction of humanity and the rest of the biophysical or natural environment.
