had significant environmental implications due to chemical agents which were used to destroy militarily-significant vegetation. Enemies found an advantage in remaining invisible by blending into a civilian population or taking cover in dense vegetation and opposing armies which targeted natural ecosystems. The US military used “more than 20 million gallons of
herbicides Herbicides (, ), also commonly known as weedkillers, are substances used to control undesired plants, also known as weeds.EPA. February 201Pesticides Industry. Sales and Usage 2006 and 2007: Market Estimates. Summary in press releasMain page fo ...

which still existed years after spraying. Not only was the vegetation affected, but also the wildlife: "a mid-1980s study by Vietnamese ecologists documented just 24 species of birds and 5 species of mammals present in sprayed forests and converted areas, compared to 145–170 bird species and 30–55 kinds of mammals in intact forest." The uncertain long-term effects of these herbicides are now being discovered by looking at modified species distribution patterns through habitat degradation and loss in wetland systems, which absorbed the runoff from the mainland.


Africa

Throughout Africa, war has been a major factor in the decline of wildlife populations inside national parks and other protected areas. However, a growing number of ecological restoration initiatives, including in Rwanda's

, have shown that wildlife populations and whole ecosystems can be successfully rehabilitated even after devastating conflicts. Experts have emphasized that solving social, economic, and political problems is essential for the success of such efforts.


Rwanda

The
Rwandan genocide The Rwandan genocide occurred between 7 April and 15 July 1994 during the Rwandan Civil War. During this period of around 100 days, members of the Tutsi minority ethnic group, as well as some moderate Hutu and Twa, were killed by armed Hutu ...

. Forests were cleared in order to provide wood for building shelters and creating cooking fires: “these people suffered from harsh conditions and constituted an important threat impact to natural resources.” Consequences from the conflict also included the degradation of National Parks and Reserves. Another big problem was that the population crash in Rwanda shifted personnel and capital to other parts of the country, thereby making it hard to protect wildlife.


World War II

World War II (WWII) drove a vast increase in production, militarized the production and transportation of commodities, and introduced many new environmental consequences, which can still be seen today. World War II was wide-ranging in its destruction of humans, animals, and materials. The postwar effects of World War II, both ecological and social, are still visible decades after the conflict ended. During World War II, new technology was used to create aircraft, which were used to conduct air raids. During the war, aircraft were used to transport resources both to and from different military bases and drop bombs on enemy, neutral, and friendly targets alike. These activities damaged habitats. Similar to wildlife, ecosystems also suffer from
noise pollution Noise pollution, also known as environmental noise or sound pollution, is the propagation of noise with ranging impacts on the activity of human or animal life, most of them are harmful to a degree. The source of outdoor noise worldwide is mai ...
which is produced by military aircraft. During World War II, aircraft acted as a vector for the transportation of exotics whereby weeds and cultivated species were brought to oceanic island ecosystems by way of aircraft landing strips which were used as refueling and staging stations during operations in the Pacific theater. Before the war, the isolated islands around Europe were inhabited by a high number of endemic species. During World War II, aerial warfare had an enormous influence on fluctuating population dynamics. In August 1945, after fighting World War II for almost four years, the

s released catastrophic levels of energy and radioactive particles. Once the bombs were detonated, the temperatures reached about 3980 °C / 7200 °F. With temperatures that high, all the flora and fauna were destroyed along with the infrastructure and human lives in the impact zones. The radioactive particles which were released resulted widespread land and water contamination. The initial blasts increased the surface temperature and created crushing winds destroying trees and buildings in their path. European forests experienced traumatic impacts which resulted from fighting during the war. Behind the combat zones, timber from cut down trees was removed in order to clear up the paths for fighting. The shattered forests in the battle zones faced exploitation. The use of heavily hazardous chemicals was first initiated during World War II. The long-term effects of chemicals result from both their potential persistence and the poor disposal program of nations with stockpiled weapons. During World War I (WW I), German chemists developed chlorine gas and mustard gas. The development of these gases led to many casualties, and lands were poisoned both on and near the battlefields. Later in World War II, chemists developed even more harmful chemical bombs, which were packaged in barrels and directly deposited in the oceans. The disposal of the chemicals in ocean runs the risk of metal-based containers corroding and leaching the chemical contents of the vessel into the ocean. Through the chemical disposal in the ocean, the contaminates may be spread throughout the various components of the ecosystems damaging marine and terrestrial ecosystems. Marine ecosystems during World War II were damaged not only from chemical contaminates, but also from wreckage from naval ships, which leaked oil into the water. Oil contamination in the Atlantic Ocean due to World War II shipwrecks is estimated at over 15 million tonnes. Oil spills are difficult to clean up and take many years to clean. To this day, traces of oil can still be found in the Atlantic Ocean from the naval shipwrecks which happened during World War II. The use of chemicals during war helped increase the scale of chemical industries and it also helped to show the government the value of scientific research. The development of chemical research during the war also lead to the postwar development of agricultural pesticides. The creation of pesticides was an upside for the years after the war. The environmental impacts of World War II were very drastic, which allowed them to be seen in the Cold War and be seen today. The impacts of conflict, chemical contaminations, and aerial warfare all contribute to reduction in the population of global flora and fauna, as well as a reduction in species diversity. In 1946, in the U.S. Zone of Germany, the United States military advised the government to prepare accommodations and employment for the people who were bombed out of their cities. The answer was a special garden program that would provide new land for the people to live in. This included land to provide food needed for the people as well. Forests were then surveyed for good soil that was suitable for crop production.This meant that the forest would be cut down in order to make land for farms and housing.The forestry program would be used to exploit the forests of Germany for future resources and control the war potential of Germany. In this program about 23,500,000 fest meters of lumber were produced out of the forests. Aluminum was one of the biggest resources affected by World War II. Bauxite, an aluminum ore and the mineral cryolite were essential, as well as requiring massive amounts of electrical power.

review concluded: "In aggregate the human epidemiological evidence is consistent with increased risk of birth defects in offspring of persons exposed to DU." According to a 2011 study by Alaani et al., depleted uranium exposure was either a primary cause or related to the cause of the birth defect and cancer increases. According to a 2012 journal article by Al-Hadithi et al., existing studies and research evidence does not show a "clear increase in birth defects" or a "clear indication of a possible environmental exposure including depleted uranium". The article further states that "there is actually no substantial evidence that genetic defects can arise from parental exposure to DU in any circumstances."

Militarism and the environment

Human security has traditionally been solely linked to military activities and defence.International Peace Bureau. (2002). The Military’s Impact on The Environment: A Neglected Aspect Of The Sustainable Development Debate A Briefing Paper For States And Non-Governmental Organisations, Retrieved from: http://www.ipb.org/wp-content/uploads/2017/03/briefing-paper.pdf Scholars and institutions like the International Peace Bureau are now increasingly calling for a more holistic approach to security, particularly including an emphasis on the interconnections and interdependencies that exist between humans and the environment. Military activity has significant impacts on the environment. Not only can war be destructive to the socioenvironment, but military activities produce extensive amounts of

Greenhouse gas emissions and pollution

greenhouse gas emissions Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and lar ...
, with the impact of military spending on carbon emissions being more pronounced for countries of the Global North (i.e.: OECD developed countries). Accordingly, the US military is estimated to be the number one fossil fuel consumer in the world.Schwartz, M. et al. (2012) Department of Defense Energy Initiatives: Background and Issues for Congress. Congressional Research Service, nlineAvailable at: http://fas.org/sgp/crs/natsec/R42558.pdf Additionally, military activities involve high emissions of pollution. The Pentagon's director of environment, safety and occupational health, Maureen Sullivan, has stated that they work with approximately 39,000 contaminated sites. Indeed, the US military is also considered one of the largest generators of pollution in the world. Combined, the top five US chemical companies only produce one fifth of the toxins produced by the Pentagon. In Canada, the Department of National Defence readily admits it is the largest energy consumer of the Government of Canada, and a consumer of “high volumes of hazardous materials”. Military pollution is a worldwide occurrence. Armed forces from around the world were responsible for the emission of two thirds of

Land and resource use

Military land use needs (such as for bases, training, storage etc.) often displace people from their lands and homes. Military activity uses solvents, fuels and other toxic chemicals which can leach toxins into the environment that remain there for decades and even centuries. Furthermore, heavy military vehicles can cause damage to soil and infrastructure. Military-caused noise pollution can also diminish the quality of life for nearby communities as well as their ability to rear or hunt animals to support themselves. Advocates raise concerns of

Retrieved from The International Peace Bureau Website: http://www.ipb.org/wp-content/uploads/2017/03/Green_Booklet_working_paper_17.09.2014.pdf Militaries are also highly resource intensive. Weapons and military equipment make up the second largest international trade sector. The International Peace Bureau says that more than fifty percent of the helicopters in the world are for military use, and approximately twenty-five percent of jet fuel consumption is by military vehicles. These vehicles are also extremely inefficient, carbon-intensive, and discharge emissions that are more toxic than those of other vehicles.


Activist responses

Military funding is, at present, higher than ever before, and activists are concerned about the implication for greenhouse gas emissions and climate change. They advocate for demilitarization, citing the high greenhouse gas emissions and support the redirection of those funds to climate action. Currently the world spends about 2.2% of global GDP on military funding according to the World Bank. It is estimated that it would cost approximately one percent of global GDP yearly until 2030 to reverse the climate crisis. Moreover, activists emphasize the need for prevention and the avoidance of costly clean up. Currently, the expense for cleaning up military contaminated site is at least $500 billion. Finally, activists point to social issues such as extreme poverty and advocate for more funding to be redirected from military expenses to these causes. Groups working for demilitarization and peace include the

Additionally, military endorsement of environmentally friendly technology such as renewable energy may have the potential to generate public support for these technologies. Finally, certain military technologies like GPS and drones are helping environmental scientists, conservationists, ecologists and restoration ecologists conduct better research, monitoring, and remediation.Lawrence, M. et al. 2015.
