Several, but antibiotics aren't necessary for human survival. If they fail
(which is not yet clear) the death rate goes up a bit and we have to be more
careful about public health measures. But, overall, we'll do fine. Epidemic
diseases are anything but new. Also, there are methods for controlling bugs
other than antibiotics which we kind of tossed aside when antibiotics came
along. There's a Russian doctor who is claiming great success with phage
therapy now that we can apply modern genetic knowledge and biotechnology.

Lowering population pressure would have nothing to do with averting
antibiotic resistance, but I digress.

Indeed, we do need an ecosystem to survive. But artificial ecosystems, by
which I mean farms and such, do just fine. They can run the carbon cycles
and the nitrogen cycles just as well as natural ones (better, really, from
our point of view). Things like the hydrologic cycles and the geologic ones
are done by the weather and plate techtonics. Most of the real work of the
ecosystems (garbage disposal and cycles for the less common elements) is done
by the germs, and they remain ubiquitous.
