1. With the continuing development of human civilization and technology, the life cycle of a product, from production, consumption to final waste, is involving more and more external adverse factors which bring about direct or indirect impact on the environment.2. Throughout the life cycle of military equipment, linear programming and concepts should be applied in all aspects, including the input of resources, the process of production, the demand of consumers, factors of environmental impact, and the formulation of policies. Noncompulsory measures should be employed to guide the enterprises to inspect and regulate every factor that could cause damage to the environment so as to reduce the environmental impact of military equipment.3. The research and development, production, deployment and replacement of military equipment or weaponry systems are necessary for the sake of national security. However, the military authorities should also consider how to minimize environmental impact.
