While making challenges for many principles and rules of international law and the traditional conception of national security, the concept does play its role in strengthening the environmental protection. However, it cannot be neglected that diflerent national interests pose an obstacle to the realization of the common interests of mankind in the envirormental protection. The article concludes that whether the concept plays its greater role in the environmental protection will depend on many factors, such as the spread of environmental awareness, the revision of the traditional conception and the balanced development of the world economy.展开更多
