Human Technology Moves the Limit—Sometimes
Agriculture, sanitation, medicine, transport and trade can weaken local limiting factors, but they do not remove global resource and waste limits.
Trace the change: resource import or health improvement raises local support, then check extraction, consumption and ecosystem degradation elsewhere.
Imported food lets a city support more people than local farms could, while the water and land impacts occur in distant regions.
No. It relocates the resource demand and may postpone the local limit.
Lowering a local limit is not the same as removing a planetary limit.
