The Development of the Concept of "Environmental Security" in the Context of Space Activity Regulation

The rapid expansion of space activities, including the deployment of satellites, the commercialization of space, and the potential militarization of outer space, has raised serious concerns about the long-term sustainability and environmental safety of outer space. This article explores the evolution of the concept of "environmental security" as applied to the regulation of space activities in international law. The paper examines how current legal frameworks, including the 1967 Outer Space Treaty and subsequent UN resolutions, address the ecological risks posed by space debris, nuclear-powered spacecraft, and military experiments in orbit. The study argues for the need to redefine and expand environmental security to encompass outer space, proposing legal and institutional mechanisms to mitigate the dual threats of environmental degradation and militarization. Emphasis is placed on the integration of environmental principles into space law to ensure the preservation of space as a global common good for future generations.
