This conclusion presents some closing thoughts on the concepts covered in the preceding chapters of this book. The book aims to understand: the complexity of environmental ethics and basic environmental problems in different media; the scientific developments and the basic philosophical background behind environmental approaches to comprehend how the relationship between human beings and nature is affected and changed in time. It also aims to understand how the field of environmental ethics is structured, the central areas of environmental ethics, and the essential levels of environmental reasoning. The book seeks rational arguments to assign moral status to nature and its non-human elements; and has two views on these matters, the anthropocentric and non-anthropocentric. It discusses how environmental issues can be regulated by law and politics; how environmental ethics can contribute to this task; the principles of political and legal measures; and the instruments that regulate environmental behaviour.
