An Arrogant Misunderstanding
The universe has existed for roughly 13.8 billion years, and our planet for about 4.54 billion years. For a long time, Earth was a hostile place. Molten rock, toxic atmospheres, no oxygen, no oceans and no stability. After hundreds of millions of years its surface cooled down. Water accumulated, and chemical processes began to give rise to life. Since then, Earth has changed countless times. Continents drifted, oceans disappeared and re-formed, entire life forms emerged and vanished. The planet has already witnessed and endured all of this and still exists. Current projections suggest that it will continue to do so for billions of years, until the sun changes and, with it, the fundamental conditions on Earth.
Modern humans (Homo sapiens) have existed for roughly 300,000 years. This means that we were absent for 99.993% of Earth’s history. Everything we know is a barely measurable fraction of that time.
And yet, it is precisely within this almost imperceptible window that we exist. Fully conscious, capable of perceiving it and reflecting upon it. It is difficult to overstate how extraordinary that is.
From a chemical and physical perspective, every human being, like everything else in the universe, is a specific, complex arrangement of atoms. In an observable universe containing hundreds of billions of galaxies, where a single galaxy holds more stars than Earth has grains of sand, our atoms have ended up on the single one planet located at exactly the right distance from its sun. A planet whose liquid water and atmosphere allow these complex arrangements of atoms to experience life. A planet whose precisely balanced forces ensure stable conditions, preventing its planetary system from either colliding or drifting apart.
If the history of the universe was compressed into a single year, modern humans would appear on the very last day of that year, in the final seconds before midnight. And yet, here we are. Not 100,000 years ago, not in some distant future, but at the precise moment in which we are the only species capable of understanding how improbable our own existence truly is.
There is no doubt that humanity is a highly developed and intelligent species. Within the context of Earth’s history, we yet appear to misjudge our position. We assign ourselves too much significance, showing a tendency toward arrogance. Do we do so despite our advanced development, or precisely because of it?
One of the most widespread assumptions of our time is that humanity is in the process of destroying the planet. This idea appears in political debates, in media and in everyday conversations. It sounds dramatic and responsible. Nevertheless, it is fundamentally wrong, because it is based on a distorted perspective.
We overestimate our importance, our capabilities, and our influence because we take ourselves as the reference. What threatens our existence automatically appears existential to everything else. The truth is: what destroys us does not necessarily destroy everything else on this planet. Unlike us, the planet does not measure existence in decades or centuries. It measures it in thousands and millions of years.
For humans, time is linear and scarce. A life lasts less than a hundred years, a civilization a few centuries. For Earth, time is something entirely different, given its 4.54 billion years of existence. It has survived global ice ages, extreme volcanic activity, and meteorite impacts without disappearing. The fact that we believe ourselves capable of achieving something the universe has failed to do for billions of years is an expression of maximal self-overestimation.
What we perceive as an existential catastrophe for the planet is, from its perspective, merely a phase. A phase that lasts until it transitions into another. Even an event that would mean the end of everything for us would represent nothing more than a phase of reorganization for Earth. What humanity perceives as an existential threat to the planet is, in reality, only an existential threat to the current forms of life. An existential threat to ourselves.
This applies to the climate crisis. And it also applies to a global nuclear war, which we tend to view as the ultimate scenario of destruction. Should such a scenario occur, experts consider the use of ballistic missiles equipped with nuclear warheads the most realistic outcome. While far more powerful nuclear weapons exist, they are impractical and therefore highly unlikely to be used. Nuclear warheads deployed on ballistic missiles typically have yields of around 300 to 330 kilotons of TNT, roughly 0.3 megatons. The meteorite impact that ended the age of the dinosaurs is estimated at 70 to 100 million megatons. None of our crises constitute an existential threat to the planet, not even to life itself. They are merely existential threats to all current life.
Life appears far more resilient than we often assume. The history of life, and the unimaginable forces involved in meteorite impacts, seem to provide sufficient evidence for this.
Earth is not a fragile system dependent on humanity. On the contrary, we are entirely dependent on highly specific conditions. A narrow temperature range, stable water cycles, functioning ecosystems, and predictable seasons. If these conditions disappear, it will not be the planet vanishing. It will be our ability to exist on it. This is a physical reality. Life is not a romantic miracle, but a fortunate interplay of phenomena. Wherever energy, chemistry, and time converge, life emerges. As long as the sun provides energy and water exists, there will be forms of life. Perhaps not ones we recognize or understand, but life nonetheless.
Earth has demonstrated this capability repeatedly. After every mass extinction, new, different and adapted life emerged.
For most of human history, survival meant fighting nature. Fighting the cold, hunger, disease, unpredictability and much more. Progress always meant gaining control. Today, this logic has reversed. For the first time, progress appears to coincide with a loss of control. For the first time, we must protect nature in order to survive ourselves. Not because we have suddenly become more moral, but because our own existence depends on it. Public debates are shaped by ideology and morality, yet this is not an ideological shift. It is a structural one, and only our continued existence is at stake.
Sustainability is often understood as an altruistic concept, a moral obligation toward the planet. In truth, sustainability should be a profoundly selfish concern. It solely serves us and the preservation of our own living conditions. The planet does not need sustainability, CO2 limits, or a 1.5 degree temperature threshold. It does not even need bans on ocean waste. A plastic bottle takes at most 5,000 years to decompose. What are 5,000 years when you are 4.54 billion years old?
This is essential to understand. Only we need these measures. Only we need sustainability. Of course, the planet in its current form is affected when it is confronted with developments such as excessive CO2 emissions and global pollution. The crucial difference compared to humanity is this: these developments harm the planet only in the short term, because the planet defines “short term” in a way humans cannot. The saying “time heals all wounds” appears to be genuinely applicable to our planet. It is more resilient than we ever will be. And it is more patient than we ever could be. Time is a decisive factor, and it is not on our side.
Progress has given us a sense of power and invulnerability. We have no natural predators, can supply ourselves, reshape landscapes, redirect rivers, and influence the climate. But influence is not control. We operate within a system that is far larger than ourselves. We can destabilize it, accelerate processes, and alter parts of it, but we cannot dominate it permanently. Earth remains the overarching system. At times, it seems we have forgotten this simple, decisive fact during our evolutionary rise.
[In a certain way, these realizations have a calming effect on me, even if the developments described are anything but reassuring for our species. They make it clear that our failure would not mean the end of the world, only the end of us. This understanding does not strip the future of its significance, but of its exaggeration. Precisely because we cannot destroy the planet, responsibility lies entirely with ourselves. And this responsibility concerns only us. Our actions do not determine Earth’s fate, but our own.
Our existence in this form is truly extraordinary and, with near certainty, not eternal. Yet at this moment, it is real. We inhabit a short, stable window within a very long history. Our greatest responsibility toward ourselves should be to avoid knowingly shrinking this window, and instead, to extend it as far as possible with everything in our power.]
