Tell the Truth SheffieldThe Destruction of Nature is a Cost of War
by Ci Davis
We have become accustomed to seeing the human impacts of war, from starvation in Sudan to the almost 100,000 killed in Gaza, but most people will be less familiar with the environmental impacts. On February 28th, another Middle East war broke out when the US and Israel launched an attack on Iran. In the first few hours, the Supreme Leader was killed, followed by the bombing of a school, killing 150 Iranian schoolgirls, and soon after, columns of smoke began to rise from targeted hits on petrochemical infrastructures.
Over the past three weeks, oil refineries, gas fields, tankers, nuclear facilities, desalination plants, oil storage tanks, air bases, and industrial areas have all been attacked. The water, marine and toxic-air pollution are a consequence of the smoke from the multiple infernos, from the widely dispersed toxic fragments, and from the many chemicals and heavy metals that escape into the soil and water, caused by thousands of bomb and missile strikes
The human and environmental costs of another war prompted two protests in Sheffield. On 21st March, 150 people demonstrated outside the Town Hall to call for an end to the war on Iran and also made connections with other current conflicts, including Gaza, Lebanon, Sudan, Ukraine and Cuba.
Our media tends to represent the environmental impacts of war as collateral damage, an unfortunate side effect, but really, they are a deliberate and targeted means of disrupting the lives of people by making their connection to land fragile or even untenable. No clearer example exists than the use of Agent Orange to defoliate the forests of Vietnam that left millions of Vietnamese and hundreds of thousands of US veterans with multigenerational health disorders and birth defects. Environmental harm is one of the ways that war impacts lives that can last many decades.
The environmental impacts of war cannot be separated from the environmental costs of the military machine itself, which is responsible for 5.5% of global greenhouse gas (GHGs) emissions, which rose by a staggering 9.4% in 2024. The US military is the largest institutional emitter of GHGs that are responsible for climate change, burning 270000 barrels of oil daily. Countries are not required to produce figures for the wartime emissions, but recently it is estimated that the war in Ukraine has produced 237 million tonnes of CO2, the Gaza conflict 32 million tonnes and in the first 5 days of the Iran war 5 million tonnes. At a time when all countries should be doing everything to reduce climate and environmental damage, the resort to war is escalating the harm.
Apocalyptic images, showing clouds of black toxic smoke blocking out the sun over Tehran, following the bombings of local oil depots on 7th March, are haunting. The oily residues, soot and sulphur-laden smoke, combined with a rare rainstorm, produced acid rain, causing immediate respiratory impacts with a lasting health legacy. For people who had already experienced chemical weapons attacks during the Iran-Iraq war, this environmental warfare was experienced as chemical warfare again.
Impact of War on the Environment Author: Sayedqudrathashimy1991 Source: Wikimedia CommonsThe Middle East is experiencing the climate crisis through water insecurity. The conflict in Syria, which displaced 1.5 million people between 2007 and 2010, was in part precipitated by drought. There are clear parallels to Iran today. After six years of drought, the water supply to Tehran was at just 11% capacity, and the shortage of water to drink or to supply agriculture contributed to protests in January 2026. War is exploiting this suffering, with all parties having targeted water and sewerage systems that, if continued, threaten to displace people throughout the region, as well as causing severe health impacts.
Most of us will be familiar with the skeletons of buildings and mountains of debris from TV images of Gaza. The 61 million tonnes of rubble are laden with asbestos, unexploded weapons, dead bodies, and untreated sewerage that has rendered the land unfit for agriculture. The clearance will take decades and burn through hundreds of thousands more tonnes of fossil fuel, and we are seeing the same thing being repeated across Iran and the Gulf.
Years after wars end, the land, air and sea will remain contaminated. Thankfully, the deliberate targeting of the environment is becoming recognised in International Law as a war crime or ecocide and can be punished under the ICC’s Rome Statute. If it is demonstrated that the military intentionally launched an attack, knowing that it will cause long-term severe damage to the natural environment, that is excessive to the military advantage anticipated, then prosecutions may follow.
As the war drags on, it risks total destruction of the oil-fields, spillage of nuclear material, and depleted Uranium contamination. These huge environmental threats will have global impacts, experienced as economic shocks and agricultural losses, threatening food security. War demonstrates our intimate connection with the land and the importance of environmental protection.
Most people oppose the war, the use of UK bases in support of it, and sending the military to the Middle East. We should make our voices heard, calling upon world leaders to respond to our opposition and pull back from the brink, for the sake of people and the planet.
