Our long-term prosperity and the well-being of future generations are in jeopardy, as biodiversity loss and the collapse of critical ecosystems not only threaten our environment, but also raise risks for the economy, public health, national security and global stability.
At this year’s UN Biodiversity Conference, currently taking place in Cali, Colombia, leaders must finally meet this crisis with the level of political commitment and funding that it warrants.
Biodiversity is often understood in terms of the variety of life on Earth — the number of species of plants, animals, and microorganisms. Its significance cannot be overstated. Biodiversity underpins the ecosystem services that sustain human life, such as water purification, flood control and climate regulation. The rapid decline of species and ecosystems — 1 million plant and animal species are on the brink of extinction — thus amounts to an existential threat.

If left unaddressed, biodiversity loss will accelerate climate change and amplify its consequences, contributing to more natural disasters and market shocks. It will also leave our agricultural systems increasingly vulnerable to hazards — from pests and pathogens to extreme weather — and deplete the ocean of critical fish stocks. This will affect the price and availability of food, causing scarcity in the Global South and compounding insecurity in already-fragile societies.
These trends will leave a growing number of people with little choice but to flee their homes in search of better living conditions.
According to the Institute for Economics and Peace, natural disasters and other ecological threats could displace as many as 1.2 billion people by 2050. These “environmental refugees” could destabilize destination countries, strain international relations and challenge security frameworks. As the planet’s total habitable area shrinks and competition for resources grows, conflict will become all but inevitable.
Biodiversity loss also threatens public health, which is inextricably linked to the ecosystems that surround us. Many diseases — including emerging infectious diseases such as mpox — can be tied directly to changes in biodiversity. As the destruction of habitats forces wildlife into closer contact with human populations, the risk of zoonotic diseases like COVID-19 rises.
To prevent such a future, all countries must recognize biodiversity loss as a security issue. This means integrating biodiversity considerations into defense and foreign policymaking. And it means financing the response — including investments in practices that protect ecosystems and ambitious measures to address the root causes of biodiversity loss, such as habitat destruction and climate change — as robustly as they would for any other security crisis.
It is estimated that tackling the biodiversity crisis will require an additional US$700 billion per year by 2030. Fortunately, at the 2022 UN Biodiversity Conference (COP15), world leaders agreed to close this gap by phasing out or repurposing harmful subsidies worth US$500 billion and raising the remaining US$200 billion. Financing from developed economies to their developing counterparts is supposed to reach at least US$20 billion per year by next year and at least US$30 billion per year by 2030.
That might seem like a lot, but it is peanuts compared with the cost of inaction.
According to projections by the Environmental Change Institute at the University of Oxford, the shocks to the global economy caused by biodiversity loss and ecosystem damage could cost as much as US$5 trillion over just five years. The world’s biodiversity-financing needs are also dwarfed by its defense spending, which totaled US$2.24 trillion in 2022.
As investing in nature amounts to one of the most cost-effective long-term defense strategies, it should be embraced by the world’s major defense spenders, beginning with the US.
As with any good security strategy, finance must be paired with international cooperation. The consequences of biodiversity loss know no borders. Countries must work together to protect critical habitats, enforce environmental regulations, and promote sustainable development practices.
As such, multilateral groups, such as the High Ambition Coalition for Nature and People, should continue to take the lead in forging international agreements and action plans that establish biodiversity conservation as a cornerstone of global security. Policymakers must continue to focus on working to meet the biodiversity framework’s “30x30” target, by encouraging and facilitating government action to protect 30 percent of the planet’s land and ocean by 2030. Furthermore, members from the Global North should increase financial support for countries in the Global South to implement necessary designations, specifically by meeting their commitment to deliver at least US$20 billion of nature finance annually by next year.
Finally, we must engage and inform the public. Education and awareness campaigns that explain the importance of protecting biodiversity can empower individuals and communities to advocate for policies that protect our natural resources, thereby helping to generate the necessary political will.
If an enemy state threatened the economy, public health, national security and global stability, we would throw everything we had at it to defend ourselves.
The biodiversity crisis is no different.

When Chinese President Xi Jinping (習近平) sits down with US President Donald Trump in Beijing on Thursday next week, Xi is unlikely to demand a dramatic public betrayal of Taiwan. He does not need to. Beijing’s preferred victory is smaller, quieter and in some ways far more dangerous: a subtle shift in American wording that appears technical, but carries major strategic meaning. The ask is simple: replace the longstanding US formulation that Washington “does not support Taiwan independence” with a harder one — that Washington “opposes” Taiwan independence. One word changes; a deterrence structure built over decades begins to shift.
Taipei is facing a severe rat infestation, and the city government is reportedly considering large-scale use of rodenticides as its primary control measure. However, this move could trigger an ecological disaster, including mass deaths of birds of prey. In the past, black kites, relatives of eagles, took more than three decades to return to the skies above the Taipei Basin. Taiwan’s black kite population was nearly wiped out by the combined effects of habitat destruction, pesticides and rodenticides. By 1992, fewer than 200 black kites remained on the island. Fortunately, thanks to more than 30 years of collective effort to preserve their remaining
After Chinese Nationalist Party (KMT) Chairwoman Cheng Li-wun (鄭麗文) met Chinese President Xi Jinping (習近平) in Beijing, most headlines referred to her as the leader of the opposition in Taiwan. Is she really, though? Being the chairwoman of the KMT does not automatically translate into being the leader of the opposition in the sense that most foreign readers would understand it. “Leader of the opposition” is a very British term. It applies to the Westminster system of parliamentary democracy, and to some extent, to other democracies. If you look at the UK right now, Conservative Party head Kemi Badenoch is
A Pale View of Hills, a movie released last year, follows the story of a Japanese woman from Nagasaki who moved to Britain in the 1950s with her British husband and daughter from a previous marriage. The daughter was born at a time when memories of the US atomic bombing of Nagasaki during World War II and anxiety over the effects of nuclear radiation still haunted the community. It is a reflection on the legacy of the local and national trauma of the bombing that ended the period of Japanese militarism. A central theme of the movie is the need, at
