File:Impact of War on the Environment.png

English: Wars have a lengthy history on Earth and have "evolved" dramatically over time. The history of imperialism, military adventurism, and extensively fuelled civil wars. The nature of war is inextricably linked to destroying physical property, killing civilians (non-combatants), and harming the environment. On the other hand, no one is concerned about air pollution. Additionally, during the Cold War era, the bipolar strategy known as mutually assured nuclear devastation (MAD) was the foundation of the ecocide. The development and testing of all components of military equipment, armament, and weaponry, as well as the requisite training in their usage, are the first steps in determining how war activity will affect the environment, notably air pollution. The background of the war has not changed, but the weapons of war are evolving and changing continually. Ancient warriors harvested the trees and woods to construct bows and arrows from the forest. The amount of deforestation comparatively was less than in civil war and nuclear wars. Today the means of war have been shaped into nuclear, chemical, and intelligent technology. For instance, the remarkable development of drone technology has brought about the idea and practice of pilotless drones by the USA to fight terrorists in Afghanistan. Nevertheless, it harmed the environment of Afghanistan. The vast amounts of money could, at least partly, be used to support sustainable development instead of being diverted toward producing weaponry and related research. This is due to emerging challenges, such as military operations, without considering sustainable development and environmental protection. The nature and amount of air pollution depend on the implemented controls. Industrial pollution and the inescapable demands of daily life can be effectively managed via the application of new technology, existing technology, and individual effort. To prevent a slow deterioration of the environment, especially the quality and temperature of the air, serious consideration must be given to the pollution caused by war activity, including during the development and testing of weapons, hardware, and operational procedures, as well as during war operations and subsequent reconstruction. In addition to the chemicals used in combat, the uncontrolled release of significant amounts of heat should also be taken seriously because it seems to build up and affect the distribution and streamlines of the airflow.
