Human behavior causes environmental problems which, in turn, affect people and whole societies. The author elaborates the role of the public in the discourse about environmental protection. As the public consists of socio-economic, legal and political actors, the behavior of those actors is of significance. With a thorough analysis of the International Social Survey Programme, this book illustrates the rocky road from the perception of environmental threats to the reaction toward them. Combining a constructivist and rational choice perspective, the author points out that there are distinctive differences between individual countries in the perception, evaluation and as well as in the reaction toward environmental issues. Neither is there a uniform path from perception to reaction, nor exists a one-size-fits-all-solution.
