Military Weapons: Pollution's Unseen Culprit?

Military weapons have a significant impact on the environment, contributing to pollution and climate change. The US military, for instance, is a major emitter of carbon dioxide, outpacing individual countries' emissions. Military activities, such as weapons testing, nuclear programs, and the use of toxic chemicals, have contaminated land, water, and soil, leading to severe health issues and even deaths among nearby residents. Armed conflicts also result in environmental damage, including air pollution, deforestation, and soil degradation, with long-lasting consequences for both humans and other species. The complex nature of military operations and the lack of clear data on emissions make addressing this issue challenging. However, the impact of military weapons on pollution is undeniable, and efforts are needed to mitigate their environmental and health effects.

Military weapons use and testing result in toxic chemical release

Military activities, including the use and testing of weapons, have been linked to environmental pollution and adverse health effects. The release of toxic chemicals and metals during military operations can contaminate the air, soil, and water, leading to severe ecological and human health consequences.

Chemical warfare agents, such as choking, blister, blood, and nerve agents, have been employed in military conflicts, including the recent Russian invasion of Ukraine. While the use of chemical weapons in international armed conflicts is prohibited under international law, their deployment continues to occur, resulting in toxic chemical release. For instance, the Ukrainian military reported over 4,800 incidents involving chemical weapons, leading to the hospitalization of Ukrainian soldiers and even fatalities.

Historical instances of chemical warfare have also left lasting impacts. During the Vietnam War, the US military employed a toxic chemical known as Agent Orange to clear vegetation. This chemical contained dioxin impurities, which have been linked to long-term health issues, including cancer, genetic damage, and birth defects among veterans and their descendants. Similarly, the use of depleted uranium in ammunition and other military applications has led to environmental contamination and potential health risks for military personnel and nearby populations.

In addition to chemical weapons, the testing and use of conventional weapons can also result in toxic chemical release. For example, the US Navy's spill of 84,000 gallons of jet fuel into a waterway and the dumping of industrial solvents into the ground near an airport impacted the health of residents in the affected areas. Metal emissions associated with military operations, including gunshot residue and embedded metal fragments, have been identified as sources of pollution, causing respiratory difficulties and other adverse health effects in veterans and civilians alike.

Furthermore, the US military's nuclear weapons tests in the Marshall Islands and on indigenous land in the US have had devastating consequences. These tests, equating to 1,000 times the power of the Hiroshima bomb, led to dramatic increases in cancer rates among indigenous people and the evacuation of entire atolls due to radiation exposure. The cumulative impact of these incidents underscores the significant contribution of military activities to climate change and pollution, with far-reaching ecological and human health repercussions.

Military metal pollution causes adverse health effects

Military metal pollution has been linked to a range of adverse health effects in both military personnel and civilians. The release of metal particles and fumes during firing and ammunition disposal has been identified as a primary exposure route, with toxic elements such as Pb, Cu, Hg, Cr, Cd, Sb, Ni, Zn, As, and depleted uranium (DU) found in weapon residue.

Studies have shown that military personnel exposed to these toxic metals experience neurological, respiratory, cardiovascular, and reproductive issues. For example, 78% of Iran-Gulf War veterans reported respiratory difficulties after serving in contaminated territories. Additionally, the disposal of ammunition in Kashiwi, Iraq, led to military personnel experiencing skin and eye problems due to exposure to sarin and cyclosarin.

The health risks associated with military metal pollution extend beyond military personnel to civilians living near affected areas. These populations experience similar health issues, including respiratory, ocular, and neurodevelopmental disorders. Children living in these areas also face adverse neurodevelopmental outcomes.

Furthermore, the environmental contamination of soil, water, and ecosystems by military metal pollution increases the risk of human exposure through inhalation, ingestion, and direct contact with embedded fragments. This has been observed in studies showing increased metal accumulation in plants, invertebrates, and vertebrate species, including fish, birds, and mammals.

The toxic effects of military-related metal exposure have been demonstrated in laboratory studies, with specific metals and metal alloys exhibiting a broader range of adverse effects than those reported in epidemiological studies. However, further research is needed to fully understand the mechanisms behind these toxic effects and the extent of their impact on human health.

Military explosives and munitions contaminate land and water

The US Department of Defense (DoD) and the Environmental Protection Agency (EPA) have recognized the contamination legacy of military munitions and explosives, estimated at 15 million acres of land. The EPA categorizes these contaminants as Military Munitions and Explosives of Concern (MEC), which are exempt from hazardous waste regulations during emergency responses. However, once the emergency has passed, the DoD is responsible for cleaning up and remediating the contaminated sites, a process that can be complex and costly.

The contamination from military explosives and munitions has severe environmental and health consequences. Soil contamination can lead to increased metal concentrations, including Pb, Cu, Hg, and Cr, which can have toxic effects on plants, animals, and humans. Inhalation of toxic fumes produced during firing has been linked to respiratory issues, with 78% of Iran-Gulf War soldiers experiencing respiratory difficulties. Additionally, exposure to chemical warfare agents and hazardous substances in munitions can result in ocular, neurological, cardiovascular, and reproductive disorders.

Furthermore, the improper disposal of military explosives and munitions has led to water contamination. For example, in 2019, it was discovered that an Air Force contractor had been dumping industrial solvent Trichloroethylene (TCE) into the ground near Tucson International Airport for 29 years. This contamination resulted in over 1,350 residents suffering from cancer and other illnesses due to exposure to polluted water.

The cleanup and remediation of contaminated sites are essential to mitigating the environmental and health impacts of military explosives and munitions. The DoD and EPA have implemented various programs and regulations, such as the Defense Environmental Restoration Program (DERP) and the Military Munitions Rule, to address these issues. However, the complexity and cost of cleanup operations, as well as the potential for interference with national security missions, present significant challenges.

Military conflict accelerates environmental exploitation

Military conflict has devastating consequences for the environment, and the exploitation of nature is accelerated during wartime. The world's military forces are some of the largest emitters of greenhouse gases, and their activities cause direct damage to nature and biodiversity.

Firstly, the use of weapons in conflict releases pollutants, destroys forests, and can render farmland unusable. Chemical weapons and pollution from weapons can remain in the environment for a long time, impacting ecosystems and human health. Artillery strikes, rockets, and landmines have been shown to cause environmental degradation and destruction. Additionally, military activities such as uranium mining, nuclear weapons testing, and the use of toxic chemicals have contaminated water, soil, and the atmosphere. This has led to increased cancer rates and other illnesses among nearby residents.

Secondly, during conflicts, there is increased resource extraction to finance and fuel military operations. Natural resources such as timber, diamonds, gold, and oil become targets, with profits used to buy weapons. This over-exploitation of resources causes extensive environmental damage that is challenging to repair. For example, the deliberate firing of oil wells in Kuwait and the destruction of Ukraine's Kakhovka Dam caused significant ecological harm.

Thirdly, the focus on military conflicts can divert attention and resources away from addressing the climate crisis. Governments may prioritize war efforts over emissions reduction and adaptation to climate change, making natural disasters worse. The displacement of people during conflicts can also lead to additional environmental damage through waste generation and the clearing of land for makeshift housing.

Finally, the rebuilding and restoration of infrastructure and nature after conflicts require significant amounts of natural resources and fossil fuels, accelerating climate change. The environmental costs of armed conflicts are immense, and international law and organizations like the UN are working to provide protection to the natural environment in relation to armed conflict.

Military emissions are a significant contributor to climate change

The US military's contribution to climate change is not limited to greenhouse gas emissions. Military activities, including nuclear weapons testing, uranium mining, and the use of toxic chemicals, have polluted land, water, and soil, with severe consequences for human health and the environment. For instance, nuclear weapons tests in the Marshall Islands were 1,000 times more powerful than the Hiroshima bomb, leading to the evacuation of four northern atolls due to radiation exposure. Similarly, jet fuel spills and the dumping of industrial solvents by the US military have been linked to increased cancer rates among nearby residents.

Armed conflicts and military activities have also been linked to environmental pollution caused by metals. Military metal pollution has been found to increase the levels of Pb, Cu, Hg, Cr, Cd, Sb, Ni, Zn, and As in the soil, with adverse health effects on both military personnel and nearby residents. Furthermore, artillery strikes, rockets, and landmines release pollutants, destroy forests, and render farmland unusable, causing long-term environmental damage and health risks.

The impact of military emissions on climate change is made more challenging to address due to the lack of clear data from military organizations. However, as the world works towards net-zero emissions targets, it is crucial to acknowledge and address the significant contribution of military emissions to global climate change.
