So, a city ecosystem might be considered "complete" when it no longer needs inputs *besides water and light* from outside the city
One crucial addition: inputs *from other cities* are essentially inputs from *inside* the city, don't count against the "no inputs" rule

no, we still mine raw materials etc--but maybe someday we can recover all our metals from garbage, idk
