That "-logy" suffix was a significant choice because it was a shift from a term scientists had been using in the preceding two centuries. (Here's where those high-school classes about a woman's taking care of a home comes in.) Before Haeckel, it was common for Europeans studying Nature to speak of the "economy" of the natural world. We can see in "economy" the same "eco-" prefix as in "ecology." But "economy" has a different suffix, from nomos. It is also from Greek, but means "management." Thus, "eco-nomy" refers to the management of some type of "house" (à la "home economics" classes).
In the case of the "economy" of Nature, however, the "house" is not a building constituted by humans. Nor are the humans the main managers. In the worldview of scientists in the 1600's and 1700's, Nature by itself was seen as having an "economy," that is, a set of efficient, purposeful interrelationships. This is why, for example, the 18th-century biologist Linnaeus was able to write:
"By the Oeconomy [i.e., Economy] of Nature,
we understand the all-wise disposition of the Creator
in relation to natural things,
by which they are fitted to produce general ends [i.e., purposes]
and reciprocal uses."
Over two-and-a-half centuries after Linnaeus -- who pioneered modern biological classification -- our current scientific knowledge and understanding of Nature's diversity and complexity has exploded. Our increasing awareness of the wildness of Nature -- its resistance to being entirely domesticated or even subdued by our attempts at "management" -- has even raised questions about whether any "house" metaphor is accurate.
There is one thing our environmental problems have shown us, however: As the 20th-century eco-theologian Sallie McFague puts it, in order for humankind to live sustainably in Nature, we need to learn this planet's "house rules."
