Lets say you have developed a Utopian society. Let's say this society has in some way made a self-sustaining fully self-sufficient ecosystem.
For the purpose of answering the question, let's say its a society of 1,000,000 (one million) humans living in a huge space station.
You would ideally want this ecosystem to sustain itself indefinitely.
How can such an ecosystem be designed to have no single-point of failure?
I imagine there would be many small points of failure, but likely these would have backups, replacements, and redundancies.. But how do you guarantee no major, or critical systems or resources won't fail?
Some systems to consider:
- Life Support
- Waste Treatment
- Raw Materials
- Living Space
This is not science fiction, there are no matter replicators, or zero-point-energy modules, etc.
