ABSTRACT
This chapter discusses the issues of environmental change directly, building a case for an approach to environmental change that focuses on the global level and that emphasizes the responsibility that everyone has to act as global environmental stewards. Where environmental issues are seen as relevant to security, these are often viewed through the lens of national security. This is the case even though ecological zones and national borders do not usually coincide, and even though unilateral state action is insufficient for responding to global environmental change. In discussions of the environment-security relationship, environmental issues are often viewed as relevant to the study and practice of security if triggering armed conflict or related threats to national sovereignty such as large-scale population displacement. At its most ethically perverse, measures to redress environmental change are viewed as threats to the economic security of states.
