Pollution prevention for NATO and the Partners for Peace (PfP) nations within the framework of environmental security is a complex and pervasive issue. There are many facets to pollution prevention and reclamation of resources previously polluted by both military and civilian activities. NATO air, land, and sea military operations must take cognizance of these matters without unduly limiting or restricting their efficacy. And new understandings of the matter, changing natural environmental laws, and international agreements are generating a multitude of new approaches to coping with these issues.
