Ecosystem Collapse Could Put UK Food Security and Climate Resilience at Risk

The loss of nature around the world could create serious risks for the UK, including threats to food security, climate stability and national resilience.

A government intelligence report has warned that the collapse of important ecosystems overseas could have far-reaching consequences. These include food shortages, rising prices, increased migration and greater global instability.

The findings highlight a simple message: protecting nature is not just an environmental issue. Healthy ecosystems are essential for a safe and secure future.

Why Healthy Ecosystems Matter

Forests, wetlands, oceans and grasslands all play a vital role in supporting life on Earth.

They help to:

• Store carbon and slow climate change
• Provide clean air and water
• Support food production
• Reduce flood risks
• Protect wildlife and biodiversity

When these natural systems are damaged, the consequences can spread across borders.

For organisations like Natural World Fund, this reinforces the importance of restoring habitats and protecting the natural world before damage becomes irreversible.

Report Warns of Growing Global Risks

The report, produced by the Joint Intelligence Committee and other government departments, highlights the potential impact of ecosystem decline overseas.

It warns that damage to major ecosystems could contribute to:

• Food shortages
• Higher food prices
• Increased pressure from migration
• Political instability
• Conflict over resources

The report has been shared with defence officials but MPs have called for the full findings to be published.

MPs Call for Greater Action on Nature Protection

Members of the Environmental Audit Committee said the UK needs to better recognise the connection between climate change, biodiversity loss and national security.

Toby Perkins, Chair of the committee, said he was disappointed that the full report had not been released.

“It’s a disappointing signal, and it would be a positive sign if we could cooperate on a response to the findings,” he said. “The minister clearly does appreciate the scale of this crisis. But I remain of the view that the government has more to do to grasp the urgency of the moment.”

MPs also called for greater investment in restoring ecosystems.

Chris Hinchliff, Labour MP and committee member, said:

“The government can summon billions of pounds for new military hardware when the defence sector calls for it. We need an equally decisive mobilisation of investment to restore the natural world on which we rely for our food, water, and clean air. Without these essentials our country has no future,” he said.

He added:

“Every critical ecosystem across our planet is on a pathway to collapse with an irreversible loss of function, and this poses huge threats to our national security. This looming crisis demands urgent action,”

“[We need] recognition from every part of government about how important preventing global biodiversity collapse is for the future of our society.”

Climate Change Is Accelerating Nature Loss

Climate change and human activity are placing increasing pressure on ecosystems worldwide.

One example is the Amazon rainforest, where scientists have warned that deforestation and rising temperatures could push the ecosystem towards a dangerous tipping point.

The Amazon plays an important role in regulating the global climate. However, continued damage could reduce its ability to absorb carbon dioxide.

This shows why protecting forests and restoring habitats are essential parts of tackling climate change.

Protecting Nature Helps Secure Our Future

Food production depends on healthy ecosystems. Farmers rely on fertile soils, clean water and pollinators to grow crops and maintain healthy landscapes.

However, biodiversity loss is putting these natural systems under increasing pressure.

Restoring habitats can help build resilience by:

• Supporting wildlife
• Improving soil health
• Protecting water supplies
• Capturing carbon
• Creating healthier landscapes

A Global Challenge Requires Local Action

Adrian Ramsay, Green Party MP, highlighted the importance of maintaining investment in environmental protection.

“If the government is serious about security it makes no sense to be cutting the international development and climate finance budgets which are crucial to tackling these fundamental threats. It’s outrageous for the government to refuse to let MPs see the full report. How can we possibly scrutinise whether the government’s response to these grave risks is adequate?”

The challenges facing nature are global, but action can begin locally.

Community-led conservation projects, habitat restoration and tree planting all play an important role in rebuilding ecosystems.

Restoring Nature for Future Generations

The message from this report is clear: nature loss creates risks for everyone.

Protecting biodiversity is essential for a healthier planet, stronger communities and a more resilient future.

Restoring the Natural World in the UK

At Natural World Fund, we support projects that restore habitats, protect wildlife and reconnect people with nature. By working together, we can help rebuild the natural systems that life depends on.
