Abstract
The latter half of the 20th Century was exclusively dominated by the conflict of the Cold War. The study of world politics included topics such as nuclear war and balance of terror. The scholars had no scope for analyzing areas of international relations for other minor issues of low politics'. Although the signing of international agreements and contracts have been at its peak for over a century, the position of the global and political economy was coined as, ?the environment with an unchanging context of international politics.' The first change was observed in the late 60s and early 1970s. The change began with a public awareness of environmental degradation due to the industrial activity. This emergence of the ecological sensibility was translated by the creation of lobbying and influential groups such as Greenpeace, and other political parties around the western world. But the real change that occurred in that respect was corollary to the end of the cold war. The collapse of the USSR resulted in a temporary end to the major threat of the time, which was ?the nuclear war.' The definition of security was revised and new threats began to bloom. This new revision and flourishing of new threats was published in the study of International relations and was seen as a challenge to the old realist theories. In the first part of this study, aspects such as reinvention and redefinition of concepts including security or threat will be scrutinized. By comprehending these concepts, the environment can then be assimilated to security. There are several patterns or trends by which environmental issues can represented as international threats. Therefore, the second part of the study will focus on environmental issues as a global threat.
