I didn't realize being "self contained bio-system" was part of the arcology definition. I thought arcologies just amounted to "a city in a building." Enclosed biosystems would be a bonus, not a defining feature.
Same here. No way arcologies have their own cattle herds, flocks of chickens (for both eggs and meat), pigs, sheep (wool anyone?), or fish.
You can grow plants on any surface exposed to the sun (
needs not be horizontal!), or in any sufficiently open space as an "inside garden" which could either have shade plants or use sun-lamps.
According to wikipedia:
Arcology, a portmanteau of the words "architecture" and "ecology,"[1] is a set of architectural design principles aimed toward the design of enormous habitats (hyperstructures) of extremely high human population density. These largely hypothetical structures, called "arcologies," would contain a variety of residential and commercial facilities and minimize individual human environmental impact. They are often portrayed as self-contained or economically self-sufficient.
So
entirely self sustained is an extreme example. They merely just need to have a near 0 footprint on the environment.
