This letter is an appeal to everyone on Earth, regardless of nationality, culture, religion, or political beliefs.
It is an invitation to reflect on humanity’s future and the urgent need to join forces in tackling the global challenges that threaten our planet and future generations.
This is not about defending the interests of any one nation or part of the world. It is about recognizing that we all share the same fate, and that only by working together can we build a better, fairer, more peaceful, and more sustainable future for everyone.
Dear fellow Earthlings,
WE KNOW that Earth is our only home. There is no Planet B. We are all in the same boat.
WE KNOW that Earth’s resources are finite.
WE KNOW that continued global population growth puts further pressure on an already strained planet. The world's population is still growing and is projected to reach around 9.7 billion by 2050.
WE KNOW that nature's delicate balance can be disrupted, sometimes with dangerous consequences.
WE KNOW that Earth's climate has changed dramatically in the past through natural processes, usually over thousands of years. Today, human activity is driving profound changes in little more than a century.
WE KNOW that feedback loops can intensify global warming, and that crossing certain tipping points could set irreversible changes in motion, at least on human timescales.
WE KNOW that, since the Second World War, humanity has acquired, for the first time, the power to destroy much of life on Earth and potentially bring about its own extinction. The dangers include nuclear war, unchecked climate change, and the uncontrolled development of artificial intelligence.
WE KNOW that our failure to act is storing up trouble for the future—and that inaction may ultimately cost far more than prevention. More frequent and severe extreme weather, melting ice, rising seas and rising temperatures threaten to transform entire regions and disrupt natural habitats. Growing pressure on food and water supplies could drive further conflict, mass migration and higher prices for essential goods.
WE KNOW that no country can solve global problems on its own. Yet after fifty years of negotiations and international conferences, progress remains far too limited. Many agreements lack binding commitments or effective means of enforcement.
WE KNOW that these challenges cannot be addressed in isolation. They are deeply interconnected, and we must act on all fronts.
WE SEE the evidence all around us: a changing climate, the horrors of ongoing wars, mounting international tensions, and the extraordinary promise—and potential dangers—of artificial intelligence.
AND YET
WE CONTINUE to consume as if there were no tomorrow, while governments pursue economic growth at almost any cost.
WE CONTINUE to pollute and pump vast amounts of CO₂ into the atmosphere.
WE CONTINUE to fight wars over scraps of territory, the ambitions of autocrats and the struggle for dominance between nations. We pour ever more money into rearmament and increasingly sophisticated, destructive weapons.
WE CONTINUE to push ahead with artificial intelligence without sufficient safeguards. Instead of agreeing on common rules and limits, countries compete fiercely to avoid falling behind.
WE CONTINUE to place economic wealth above all else and treat profit as the sole purpose of economic activity, overlooking human wellbeing and respect for nature.
WE CONTINUE, as a world, to have more children than our current patterns of consumption and resource use can sustainably support.
DO WE REALLY WANT TO GO ON LIKE THIS?
We can—and perhaps we will. But then we must face the likelihood of a worsening situation and accept responsibility for the consequences.
THINK about the generations to come, and the world they will inherit between now and the end of this century. Some of those who will live through that future are already here. They are today's children. Our children. Our grandchildren. They will live in the world we are shaping right now.
WE FEAR that taking action will be expensive, that we will have to give things up, that our living standards will fall or that we may lose our jobs. So we would rather not think about it. We tell ourselves there is nothing we can do—that one person cannot make a difference.
BUT WE ARE WRONG.
In fact, the opposite may be true.
Of course, meeting these challenges will require enormous investment—not just in the measures themselves, but in ensuring a fair and socially sustainable transition, one that leaves no one behind and does not place the heaviest burden on those least able to bear it.
So where would the money come from? In principle, the answer is straightforward. What is missing is the collective will.
For a start, we could end conflicts and reverse the arms race. Cutting military spending would free up substantial resources while reducing one of the three great threats we face: nuclear war.
Another vast source of funding could be unlocked by tackling tax evasion effectively: ending the use of tax havens, making major financial transactions traceable, stopping shell companies from being used to avoid taxes, ensuring that profits are taxed where they are generated, and making taxation of very large fortunes and profits more progressive.
And in a peaceful world built on close international cooperation, rapid technological progress—supported by the right policies—could help raise living standards sustainably across the globe, reduce working hours and make decent employment available to all.
BUT HOW COULD WE MAKE ANY OF THIS HAPPEN?
If we have achieved so little so far, what makes us think we can change course now?
If we simply wait for governments to take the initiative, we may wait forever. Nearly 200 countries have different interests, priorities and circumstances. How can they agree without an independent body to help bring them together? Too often, political leaders look no further than the next election. Winning votes and holding on to power take precedence over what may happen in ten, twenty or thirty years—particularly when action carries an immediate cost but the benefits lie far in the future.
The impetus must come from ordinary people: a worldwide movement of millions, perhaps hundreds of millions, of people of every age and background, pressing governments to establish a global authority with real powers to make decisions, oversee implementation and enforce agreed rules. A WORLD COUNCIL.
Not a world government with authority over everything. Not a body that replaces individual states. Rather, a democratic global institution whose remit is strictly confined to challenges that no country can solve alone. It would bring together representatives from different nations and draw on the best scientific expertise available. It would be transparent, accountable and democratically legitimate, with powers limited to genuinely global issues.
SO HOW DO WE BUILD A GLOBAL MOVEMENT?
We can start by abandoning the belief that individuals are powerless. We have something no previous generation has had: the ability to reach people across the world almost instantly, on an unprecedented scale.
Getting started does not require a vast organisation, huge sums of money or major personal sacrifices. It begins with a shared goal—and a determination to make it heard.
No-Extinction (www.no-extinction.org) already offers ways to take part: a website explaining the issues, a global petition, a discussion forum, a twenty-minute documentary, the book The Century of Choices, the strategy simulation game LAST CHANCE—playable on the website or available free on Google Play, with no advertising—and educational and outreach materials.
Signing the global petition is free and takes just a few minutes. It is a simple way to show support, with the option to receive occasional updates on the initiative's progress.
We also invite associations and organisations to join forces in a GLOBAL ALLIANCE, united by a common purpose.
Each of us can help by talking to friends and family, sharing these ideas online, and reaching out to associations, schools, universities, scientists, journalists and public figures.
If every person inspired just a few others, the message could spread steadily across national borders, cultures, religions and political divides.
This is not about advancing the interests of any one country, party or group.
It is about protecting the future we all share.
A movement large enough to be heard around the world could put increasing pressure on governments and international institutions, until the proposal for a World Council could no longer be ignored.
It would not be easy. There would be resistance, conflicting interests and formidable obstacles. But no great change in history has come without a struggle.
CAN WE REALLY ACHIEVE THIS?
We do not know. But we do know we have to try. We must act before it is too late.
UNDERSTAND. DECIDE. ACT.
