Warfare's Environmental Toll: Conflicts Eject Millions of Tonnes of Greenhouse Gases
- 1
Military conflicts are a major source of environmental degradation, releasing significant greenhouse gases and toxins.
- 2
The initial 14 days of the US-Israel conflict on Iran reportedly emitted over 5 million tonnes of greenhouse gases.
- 3
This emission level surpassed the combined annual output of more than 84 countries, highlighting the scale of military pollution.
- 4
War activities directly damage ecosystems, weaken environmental governance, and contribute to long-term ecological harm.
- ●Military activities are significant contributors to global pollution and greenhouse gas emissions.
- ●The US-Israel conflict on Iran's first 14 days reportedly released over 5 million tonnes of greenhouse gases.
- ●This amount of emissions exceeded the combined annual output of more than 84 countries.
- ●Warfare causes direct damage to ecosystems, releases toxins, and weakens environmental protection efforts.
Military Environmental Impact
This refers to the wide-ranging damage caused to the natural environment by military activities, both during peacetime and armed conflict. It includes direct destruction of habitats, pollution from weapons and vehicles (e.g., greenhouse gases, heavy metals, unexploded ordnance), resource depletion, and the weakening of environmental governance in conflict zones. These impacts can be immediate and catastrophic, or long-term and insidious, affecting climate, biodiversity, and human health.
Simple Analogy: Imagine a large factory operating without any environmental regulations, constantly emitting smoke, dumping waste, and consuming vast resources. Military operations, especially during war, often function similarly, but on a much larger and more destructive scale, with little to no accountability for their environmental footprint.
Climate Change
Military emissions, particularly greenhouse gases from fuel consumption and destruction, directly contribute to global warming and climate change.
International Environmental Law
The article implicitly raises questions about the applicability and enforcement of environmental protection laws and conventions during armed conflicts, where accountability is often challenging.
Sustainable Development Goals (SDGs)
Environmental damage from war undermines several SDGs, particularly those related to climate action (SDG 13), life on land (SDG 15), and peace, justice, and strong institutions (SDG 16).
Environmental Security
The degradation of natural resources and ecosystems due to conflict can exacerbate existing tensions and create new security challenges, linking environmental issues directly to national and international security.
Exam Relevance
GS Paper 3: Environmental pollution and degradation, environmental impact assessment. GS Paper 2: International relations, global environmental agreements.
General Awareness: Environmental issues, current events.
General Knowledge: Environmental security, impact of military operations.
General Science: Environmental pollution, climate change.
Previously Asked (PYQs)
In the context of WHO Air Quality Guidelines, consider the following statements: 1. The 24-hour mean of PM2.5 should not exceed 15 μg/m3 and annual mean should not exceed 5 μg/m2. 2. In a year, the highest levels of ozone pollution occur during the periods of inclement weather. 3. PM10 can penetrate the lung barrier and enter the bloodstream. 4. Excessive ozone in the air can trigger asthma. Which of the statements given above are correct?
Answer: 1 and 4 only
Why is there a great concern about the 'microbeads' that are released into environment?
Answer: They are considered harmful to marine ecosystems.
Consider the following statements regarding mercury pollution: 1. Gold mining activity is a source of mercury pollution in the world. 2. Coal-based thermal power plants cause mercury pollution. 3. There is no known safe level of exposure to mercury. How many of the above statements are correct?
Answer: All three
Expected Questions
- ★UPSC may ask: 'Analyze the multifaceted environmental ramifications of armed conflicts and their implications for global climate goals and biodiversity conservation.'
- ★SSC/Banking may ask: 'Which type of pollution is significantly increased by military conflicts?' or 'What is the approximate greenhouse gas emission reported from the initial days of the US-Israel conflict on Iran?'
- ★Defence exams may focus on the long-term environmental challenges faced by post-conflict regions and the role of military in environmental restoration.
Topic Frequency
Medium-High, especially for UPSC, as environmental impact of human activities and global events is a recurring theme.
Key Terms
Gases in Earth's atmosphere that trap heat, contributing to global warming.
The deterioration of environmental quality and decline of biodiversity within an ecosystem.
Environmental contamination and damage resulting from military activities, including emissions, waste, and destruction.
The processes of decision-making involved in the control and management of the environment and natural resources.
Must Remember
- •Wars are major polluters, contributing significantly to global greenhouse gas emissions.
- •Military conflicts cause direct and long-term ecosystem damage, biodiversity loss, and release of toxins.
- •The environmental impact of war extends beyond immediate conflict zones, contributing to global climate change.
- •The reported emissions from the US-Israel conflict on Iran (first 14 days) exceeded 5 million tonnes of GHGs.
Exam Tips
- •Understand the specific types of environmental damage caused by warfare (air, water, soil pollution, biodiversity loss, resource depletion).
- •Be aware of the challenges in regulating military environmental impact under international law.
- •Connect this topic to broader themes like climate change, sustainable development, and international security.
