Four humans recently looped around the Moon. Their vessel, an Artemis capsule, was a thin metal shell whose life-support system kept them alive: it provided a carefully balanced atmosphere, a closed water loop, a finite supply of food and a means for disposing human waste. The life support was not optional. It was a necessity.
Consider this: not once in the history of human spaceflight has an astronaut been known to tamper with their life support system. No one has ever decided to vent some oxygen for fun. No one has argued for a personal right to increase their CO₂ output. Sabotage is unthinkable – socially intolerable. Their fellow crew members and mission control would intervene immediately.
Now consider Earth.
We are doing to our planetary life support what no astronaut has done to theirs. We are damaging it – venting carbon, acidifying the oceans, stripping topsoil and collapsing biodiversity – not maliciously, but with a shrug. It is legal. It is profitable. And in most circles, it is entirely socially acceptable.
The Victorian novelist George Eliot would have understood why. In Middlemarch, she showed us a town that preferred a satisfying, simple myth (that a charismatic quack can cure ills) over difficult, complex truths (the role of germs, statistics, slow systematic change). Humans, she argued, do not naturally reach for what is true. We reach for what is near, simple and emotionally rewarding.
Climate science is the anti-myth. It is delayed, diffuse, impersonal and global. It asks us to change behaviour today for a benefit that will arrive decades away, elsewhere on the planet, for people we will never meet.
The Artemis crew members live by a different narrative. They are guided by a simple, undeniable truth. That they are in a small, fragile vessel. The life support is essential. Damaging it is not an option.

Earth is a vessel too. It is just larger, its support systems less visible, and the consequences of damage slower to arrive. As the economist Kenneth Boulding argued 60 years ago, we must learn to see our planet as a closed system – not an open frontier.
What narrative could protect Earth like it protects astronauts?
Not a policy paper. Not a carbon tax (though we need those). A story.
We have candidate myths already. None is perfect, but each is more powerful than the cold scientific facts.
The one pane of glass narrative outlines that Earth is not a planet we live on. It is a pressurised cabin with a single irreplaceable window. Every tonne of CO₂ scratches a crack in that glass. You wouldn’t hammer the Artemis capsule window. Why do it here?
The blood of the body myth portrays the biosphere not as nature but as the collective and extended organ system of humanity. Deforesting the Amazon and burning oil are not business as usual, they are acts of self-harm.
The crew of the damned narrative hinges on the concept that you are not a consumer. You are a temporary tenant on a multi-generational voyage. Nature and the previous shift built the vessel. The next shift will inherit it. To degrade Earth’s systems is to defile the ancestors and curse the children. That is not a crime. It is a sin that will outlast your name.
None of these stories will work if they remain metaphors. They become common sense only when they are visibly, socially and economically enforced – when a CEO who opens a new coal mine is treated with the same universal horror as an astronaut reaching for the oxygen valve.
Imagine every human decision – personal, professional, political – tested against one simple question: “If we were in a capsule looping around the Moon, would this be a safe use of our shared life support?”
Repeated sufficiently, the right conclusion would become habitual. For those resisting, the rest of the crew would intervene. On Earth, there is no mission control – only us.
