Ecosystem
= An Ecosystem is a web of relationships that makes a household (oikos) viable over time, encompassing the flows of nourishment, care, and continuity that sustain life across generations. [1]
Context
Ernesto van Peborgh reflects on the deeper meaning:
"I've come to believe that the word ecosystem has been quietly telling us the truth all along, if only we slowed down enough to listen.
The 'eco' comes from oikos — the ancient Greek word for home. Not a building. Not an asset. A lived household. A place where life organizes itself, where nourishment circulates, where continuity is maintained across generations. A place you belong to before you manage it.
Seen this way, an ecosystem is not simply a system with inputs and outputs. It is the web of relationships that makes a household viable over time. Forests know this. Rivers know it too. So did cultures that endured long before we learned to optimize everything that moved."

Description
Andrea Farias:
"An ecosystem is a biological community of interacting organisms, their physical environment, and the forces that act on them. Every organism, whether it's a plant, animal, microbe, or human, depends on the flows of energy within the system to survive. We live within a single ecosystem: planet earth. However, breaking down the planetary ecosystem into smaller components, such as a pond, forest, ocean, city or bioregion, can help us understand it better."

Characteristics
Andrea Farias:
"A healthy ecosystem has the ability to maintain its structure (organization) and function (vigor) over time in the face of external stress (resilience). This involves the interrelationship between organisms (biodiversity), the ability to complete essential processes (productivity), and the capability to adapt under pressure (adaptability). Maintaining ecosystem health is essential for ensuring the continued flow of energy, vital services and resources, therefore supporting the well-being of all life on Earth.
+ Organisation: Bio(cultural)diversity, the interrelationship between creatures. A diverse system generally has more adaptive capacity and is therefore more likely to cope with change.
- Vigor: what is its ability to complete essential processes, the productivity of a system.
- Resilience: to what extent can health be maintained under pressure, capability to adapt."

Discussion
Ecology vs. System
"What we tend to call a 'system' today is often abstract — designed from the outside, controlled, replaced when it no longer performs. A traffic system. A software system. A financial system. Useful, efficient, and ultimately disposable.
But an eco-system is something else entirely. It cannot be separated from place, from relationship, from responsibility. It asks for care rather than domination, participation rather than control, continuity rather than extraction.
The quiet implication is radical: there is no external manager of the household of life. Everyone who lives within it is shaping it, for better or worse, simply by how they show up.
This is why ecology and economy were never meant to be enemies. They were once two ways of speaking about the same concern — how a household sustains itself without consuming its own future. Only later did economy drift away, learning to manage flows of value as if they were detached from the living house that made them possible."
