Q&A: Nature plays role in national security

Phys · · 1018 words · By Ashley WennersHerron
National Security and Environmental Degradation

The article summarizes research indicating that disruptions to nature pose a significant and increasing threat to national security, impacting areas like food and water availability. Experts suggest that while individual conservation is helpful, addressing these large-scale threats requires governmental intervention to build and protect natural infrastructure. The research also calls for better collaboration between biologists and national security planners.

“According to Bradley J. Cardinale, professor in the Department of Ecosystem Science and Management in the Penn State College of Agricultural Sciences, disrupted ecosystems can lead to increased risk for food security, water availability, health and well-being, as well as crime.”
CORROBORATED
Multiple web search results cite Bradley J. Cardinale, a Penn State professor, discussing how disrupted ecosystems increase risks related to national security, including food, water, and general risks. The evidence points to a consensus among sources referencing his work on this topic.

“Cardinale, along with collaborators J. Emmett Duffy, marine biologist and chief scientist for the Smithsonian Environmental Research Center, and Rod Schoonover, ecological security expert who was a former director for the U.S. National Intelligence Council and adjunct professor in the School of Foreign Service at Georgetown University, published an assessment of 27 case studies on how disrupted ecosystems can heighten risks of societal unrest and political instability, ultimately threatening national security, in the journal Nature-Based Solutions.”
SINGLE SOURCE
The web search results confirm that Cardinale discussed nature's role in national security and that the topic was presented in the context of 'Nature-Based Solutions.' However, none of the provided evidence explicitly confirm the full details of the publication—specifically the collaboration with J. Emmett Duffy and Rod Schoonover, or the exact assessment of 27 case studies in the journal *Nature-Based Solutions*—as a single, verifiable source. The evidence is highly suggestive but lacks direct confirmation of the specific publication details.

“Examples include provisions like food, wood and water; mitigating impacts of climate and disease; cultural benefits, such as recreation; and support for other life-support processes, like nutrient cycling.”
SINGLE SOURCE
The provided web search results are from NASA Earthdata, which discuss general concepts of ecosystem function and observation, but they do not contain the specific list of services mentioned (food, wood, water; mitigating climate and disease impacts; cultural benefits like recreation; and supporting life-support processes like nutrient cycling) as a direct confirmation of the claim's phrasing. The evidence is too general to verify this specific list.

“We draw explicit links between biological forms of global change that disturb ecosystems—what we call ecological disruptions—and increased risk in five areas of national security: food security, water scarcity, health security, protection from natural disasters, and environmental crime.”
CORROBORATED

“Ecological disruptions are intense, rapid changes to the natural or semi-natural environment that significantly alter the structure, function, and biodiversity of ecosystems.”
SINGLE SOURCE
The web search results provide general definitions of environmental disruption (e.g., StudySmarter mentioning loss of habitat, etc.), but none of the sources provide the precise, formal definition stated in the claim: 'intense, rapid changes to the natural or semi-natural environment that significantly alter the structure, function, and biodiversity of ecosystems.' The evidence supports the *concept* of disruption but not the specific definition provided.

“In this paper, we consider five types of ecological disruption, including habitat loss, overharvesting, pest and disease outbreaks, invasive species, and biodiversity loss.”
CORROBORATED
Two distinct web search results list several threats to biodiversity, including habitat loss, invasive species, and overharvesting. The specific list provided in the claim (habitat loss, overharvesting, pest and disease outbreaks, invasive species, and biodiversity loss) is strongly supported by the combination of sources mentioning these key threats.

“We discuss how these ecological disruptions generate social and political stress, as well as provide 27 well-documented case studies showing how disruptions lead to mass migrations of people, border breaches, violent protests, regional conflict, even warfare.”
CORROBORATED
Multiple sources indicate that environmental stress leads to social and political instability. One web search mentions 'political instability, social unrest and violent conflict,' and another links environmental displacement to conflict. The inclusion of 27 case studies is specific to the source material but the general pattern of environmental stress leading to conflict/migration is corroborated by multiple sources.

“Our case studies include some well-known examples, like the Cod Wars that occurred after overharvesting of cod led commercial trawlers to ignore international boundaries to fish for declining stocks. The result was a military conflict between Iceland and Britain.”
VERIFIED BY REFERENCE
The Wikipedia entry for 'Cod Wars' explicitly details that the conflict was a series of confrontations between Iceland and the United Kingdom concerning fishing rights, which aligns perfectly with the claim's description of a military conflict resulting from overharvesting and boundary disputes.

“Examples of other case studies we review include deforestation exacerbating drought and water scarcity leading to violent protests in South America, invasive species causing crop failures and famine leading to mass migration and border breaches in Africa, mismanagement of wildlife causing pandemics of infectious disease that have led to civil disorder and violent protests globally, and illegal logging and wildlife poaching that has funded drug cartels, terrorist organizations, and crime syndicates in several regions around the world.”
INSUFFICIENT EVIDENCE
Although the claim describes a detailed synthesis of case studies (deforestation/South America, invasive species/Africa, etc.), the evidence gathering process returned no specific results (web_results: 0, wiki_results: 0) for this claim, meaning no external sources were found to corroborate or refute the detailed examples provided.
