Observance Daily What day is today, and why are we celebrating it?
Environment in War Day, observed on November 6, is the United Nations International Day for Preventing the Exploitation of the Environment in War and Armed Conflict. It highlights how war damages the environment — and reminds the world that protecting nature matters even, and especially, in wartime.
When we think of the costs of war, we usually think of lives lost, cities destroyed, and families displaced. But war also scars the natural world: polluted water, destroyed forests, poisoned soil, and ruined ecosystems. This UN observance asks us to look at the environmental damage that armed conflict leaves behind, and to insist that the environment be protected even in times of war.
What is Environment in War Day?
The International Day for Preventing the Exploitation of the Environment in War and Armed Conflict is a United Nations observance held on November 6 each year. It draws attention to the ways in which war and armed conflict exploit and damage the environment, and to the need to protect natural resources even amid hostilities.
The day reflects a simple but powerful idea: the environment is a silent casualty of war. Wells are poisoned, forests are felled for military purposes, farmland is ruined, and ecosystems that took generations to form can be destroyed in a matter of days.
How war damages the environment
Armed conflict harms ecosystems in many ways. Oil spills from damaged facilities and ships can coat coastlines and poison marine life. Forests may be cleared for military operations or to deny cover to opposing forces. Water supplies can be contaminated or deliberately damaged, leaving civilians without safe drinking water long after fighting ends.
Soil can be poisoned by munitions, fuel, and chemicals, making farmland unusable for years. Wildlife habitats are shattered, and species already under pressure can be pushed closer to extinction. Perhaps most sobering of all, environmental damage from war can last for generations after the fighting stops — the wounds outlive the wars that caused them.
How to mark Environment in War Day
Learn how conflict harms ecosystems. Read about the environmental toll of war — oil spills, deforestation, damaged water supplies — and share what you learn. Understanding the problem is the first step toward preventing it.
Support organisations working on protection and clean-up. Many organisations work on environmental protection and post-conflict clean-up, from removing hazardous materials to restoring damaged land. Consider supporting their work with a donation or by spreading the word.
Remember that damage lasts generations. Reflect on the fact that environmental harm from war does not end with a ceasefire. Advocate for the principle that the natural world deserves protection in conflict, and that those who damage it should be held accountable.

Frequently asked questions
When is Environment in War Day? It is observed on November 6 each year as a United Nations observance.
What is the full name of the day? The International Day for Preventing the Exploitation of the Environment in War and Armed Conflict.
How does war damage the environment? Through polluted water, destroyed forests, poisoned soil, ruined ecosystems, oil spills, and damage to water supplies — harm that can last for generations after fighting ends.
Why does the environment need protection during war? Because nature is a silent casualty of conflict, and because the damage war does to the environment can undermine recovery and harm communities for generations.
Why Environment in War Day matters
Environment in War Day matters because it insists on a truth that is easy to overlook: war does not only destroy the present, it poisons the future. A forest cut down in wartime, a well poisoned, a coastline coated in oil — these wounds persist long after the guns fall silent.
On November 6, take a moment to remember the environment as a casualty of war, and to support the work of protecting and restoring it. Peace is not only the absence of fighting; it is the restoration of the world we all share.
