Statement
Crop disease, pollinator loss, loss of required microbial function, pathogen increase, reduced diversity, instability, salt accumulation, and harmful genetic change can propagate across tightly coupled loops.
Evidence dimensions
- Basis
- modeled
- Readiness
- early research
- Confidence
- supported
Assessment rationale
Observed crop, microbial, biofilm, water, and enclosed-facility mechanisms support the listed failure pathways; propagation across a worldship remains a system-dependent model.

Assumptions and limits
The assessment applies to this bounded statement and the cited source scopes. A source can support one relationship without validating a generation ship, and an editorial grade does not substitute for independent review or representative demonstration.
What would change this conclusion?
Representative integrated fault experiments measuring propagation, containment, health effects, ecological state, and recovery would replace generic pathways with bounded probabilities and margins.
