Humanity has already crossed a boundary.
We are no longer a species confined to Earth.
Thousands of satellites orbit our planet, the Moon and Mars have re-emerged as objects of exploration, and outer space is increasingly being transformed into a domain of industry and strategy. This shift is not merely a technological advancement—it is a transformation in the very mode of human existence.
Yet our thinking remains Earth-bound. We still understand ecology as a matter of “environmental protection,” treating nature as a backdrop to human activity. This gap—where action has expanded into space while thought remains confined to Earth—is the fundamental crisis we now face.
Conventional ecology cannot adequately explain this condition.
Félix Guattari, through The Three Ecologies, redefined ecology as a network of relations across three layers: the mental, the social, and the environmental. This was a profound shift, extending ecological thinking into subjectivity and social systems. Yet it still rests on a hidden assumption: that ecology is contained within the Earth.
This assumption can no longer be sustained.
We now occupy orbital space, leave traces in the cosmos, and possess the capacity to affect the environments of other planets. Space is no longer an empty void. It has become both an extension of human activity and a new ecological domain for which we bear responsibility.
This is where this work begins.
I propose that we redefine ecology.
Ecology should no longer refer solely to the relationship between living organisms and their environments. It must instead be understood as a network of relations encompassing matter, energy, information, and possibility. This network is not limited to Earth; it extends to stars, galaxies, and even unrealized domains of potential existence.
I call this expanded concept Cosmoecology.
Within Cosmoecology, ecology consists of four dimensions:
mind, society, nature, and the cosmos. These layers cannot be separated. Human thought shapes social structures; society transforms environments; environments are constrained by cosmic conditions. At the same time, human technology and civilization are beginning to reshape cosmic space itself. All of this forms a single, interconnected system.
To understand this system, the key concept is interconnectedness.
Nothing exists in isolation. Environmental issues are not merely about nature, nor are technological issues solely about humanity. Everything is entangled, and this entanglement now extends to a cosmic scale.
At the physical level, this system is governed by the Second Law of Thermodynamics.
The universe tends toward disorder, yet life and civilization generate local pockets of order within that flow. We are both part of this order and agents that extend it. In this sense, civilization is not merely the result of progress—it is a local resistance to entropy.
But this resistance comes at a cost.
As civilization expands, it produces new risks: orbital debris, collisions, resource conflicts, and uncontrollable technologies. Expansion does not guarantee survival. On the contrary, unchecked expansion may accelerate collapse.
For this reason, we require a new ethics.
This ethics cannot remain anthropocentric. It must account for future forms of life and civilizations not yet realized, and it must minimize irreversible damage to cosmic environments. We are no longer merely beings who “protect the Earth,” but beings whose actions shape the conditions of the cosmos itself.
This ethical shift must be institutionalized through policy and governance.
Space can no longer remain an unregulated domain. Orbits must be managed, debris must be removed, planets must be protected, and resource extraction must be governed by responsibility. This is not optional—it is necessary.
Economics, too, must transform.
Activity in space is not simply an expansion of markets; it requires a new structure of accountability. Pollution must become a cost, and sustainability must be measurable as value. Otherwise, we will replicate in space the same failures we produced on Earth.
Ultimately, we stand before a choice.
We can continue toward uncontrolled expansion, or we can pursue ecological integration. The former promises rapid growth but increasing instability; the latter imposes constraints but enables long-term sustainability.
Cosmoecology makes this choice explicit.
Ecology is no longer merely a question of environmental protection. It is a question of how we exist in the cosmos. We are no longer just a species that survives—we are a civilization that designs and transforms environments. That demands a corresponding transformation in thought and responsibility.
Cosmoecology is not merely a theory; it is a perspective.
It is a way of understanding humanity, civilization, and the cosmos as a single interconnected system—and of sustaining that system responsibly.
The question is now simple:
How will we exist in the cosmos?
