Nowadays humans struggle to supply and attain longer and more appropriate life time. Introducing new technologies, which, speeded up by modernization and industrialization, is the main subject in many branches of science to improve the human’s life; but this rate of innovation is not always pleasurable. As seen in many cases, side effects of using new technology come up as warning signs, and lead to huge environmental and humanitarian disaster with irreversible impact. Moreover, most of these technologies might be applied in different kinds of warfare where nations use high-Tech as tools to reach other’s resources and raise their economic benefits. As in most wars that happened in the world, updated technologies have been applied to overcome the combatant, which finally shows up as damages on the environment, economy, civilians and soldiers. In this study we reviewed the reasons of shaping warfare and its consequences in different aspects of environment, civilians, soldiers and economy. The questions I followed to answer were: What are those main factors that induced by technology to form different kinds of warfare? And, can technology be altered as a tool to make a war more environmentally friendly? To answer these two main questions, we need to know reasons for shaping warfare a) Economy, b) Ideological/religious, and c) Power/pride/love which raise many theories such as Economic, Behavioural, Evolutionary, Demographic, Rational, and Political science theory. In 1990 members of the committee of environmental issue discussed development of technology in the future which should follow by consideration of global environmental issue. Therefore, new technology should bring solution to environmental problems. Nowadays technology creates some kind of competition, not only in combat, but also in cold war. According to reviews of many studies, the harshness of war increases and the aftermath becomes more severe on the environment and societies, consequently irreversible rehabilitation in short and long term. Applied technologies in some warfare have been considered by their impact on natural and human environment. As a case study I considered the recent war in Libya and its consequences, not only in the country, but also its impact on other nations and neighbours as well. Strict international laws is needed to explicit and declare the rights of each individual and nation to prevent and ban any activities in the term of war crime. Also groups of authentic authorities should set up to conduct an investigation into each activity in countries and survey on introduced technologies to ensure them about their result and consequences. Finally some reviews were released about how international committees and conventions, declarations and agreement has been set to prevent and prohibit crime in wars, and some international laws has been brought to guide nations about their rights and responsibility against each other.
