I don't believe that *ecology* is a good tag here, because it's so tangent that it'll most likely never be used again, especially as posts on ecology itself are off topic here. But I guess the majority thought differently.

The words *ecology* and *economy* are very similar. [Ecology](http://en.wikipedia.org/wiki/Ecology) derives from the words [*οἶκος*](http://en.wiktionary.org/wiki/%CE%BF%E1%BC%B6%CE%BA%CE%BF%CF%82#Ancient_Greek) + [λογία](http://en.wiktionary.org/wiki/-%CE%BB%CE%BF%CE%B3%CE%AF%CE%B1#Ancient_Greek), i.e. the *study of the house/household*. [Economy](http://en.wikipedia.org/wiki/Economy) derives from the words [*οἶκος*](http://en.wiktionary.org/wiki/%CE%BF%E1%BC%B6%CE%BA%CE%BF%CF%82#Ancient_Greek) + [νόμος](http://en.wiktionary.org/wiki/%CE%BD%CF%8C%CE%BC%CE%BF%CF%82#Ancient_Greek), i.e. the *laws of the house/household*. In modern usage, ecology studies, among other things, *movement of materials and energy through living communities* (e.g. [Wikipedia](https://en.wikipedia.org/wiki/Ecology)). Economy, in modern usage, is defined by [Wikipedia](https://en.wikipedia.org/wiki/Economy) as *An economy or economic system consists of the production, distribution or trade, and consumption of limited goods and services by different agents in a given geographical location*.
An interdisciplinary field is called [ecological economics](https://en.wikipedia.org/wiki/Ecological_economics), which is *the treatment of the economy as a subsystem of the ecosystem* (again according to Wikipedia).

I've often wondered by ecologists and economists seem, often quite literally and physically, separated fields. Ecological economics considers the economy as a subsystem of the ecosystem. Why is this not standard? How can the economy ever *not* be a subsystem of the ecology, and why is not all economics "ecological economics"? Or is it?

I think you are right to say that an economy ***is*** *always* a subsystem of a larger ecosystem, but it needs ***not*** always be **modeled** as such.

It may be interesting to have a precise and elaborate model of the solar system taken in isolation, independently of its interactions with the rest of the galaxy, other galaxies, etc. In very much the same way, there are many good reasons to build a model of an economic system without accounting for how it fits in a more general ecosystem.

It is not "standard" because economy and ecology are two fundamentally different things. We cannot really create or control an ecological system to the same extent we can create and control an economy.

We can however create an economy where none existed before, because an economy is not a "natural" thing at all. It is governed by the financial, tax and contract laws that we as a society create. We can create an economy where none existed before (e.g. internet, intellectual property, etc). We can't do any of that in an ecosystem. We can have two (or more) economic systems existing alongside each other whereas we can't have that in an ecology. The "rules" of an ecological system are immutable.
