Chapter 1 introduces the main themes of the book. It highlights three vantages on what it means to value nature on an aesthetic basis – philosophies of environmental aesthetics, aesthetic theories for the visual arts, and practices of international environmental law. It provides an outline of the book over the eight chapters, explaining how the different vantages on nature’s aesthetic value inform the analysis of photographic images in the book’s case studies of the World Heritage Convention, the Whaling Convention and the Biodiversity Convention. An overview of the international materials examined, and the visual art analysed, is provided. Here, particular mention is made of the book’s use of the rules and documentation of the decision-making processes of the World Heritage Committee, the International Court of Justice, and the Conference of the Parties to the Biodiversity Convention. In a final section, the scholarly theories that inform the book’s methods of analysis are introduced. This includes discussion of academic literature on law and image, sometimes called visual jurisprudence, and debates among philosophers of environmental aesthetics and theorists of visual art.
