The gas seems to have a strange quality whereby it can both change humans into zombies but also drives zombies away in large concentrations (since no zombies were seen at ground zero while the haze was there.)

So here's my idea:
What if the haze is not only the cause of the outbreak (possibly) but also the key to defeating Ink. If a large concentration of gas were to be released to flood Ink's tunnels while the zombies are trapped inside (seal up the entrances that Michael, Vic, and Saul are ferreting out) it could kill them. And this could explain why Michael is going back over his journal, he's preparing himself to make a sacrifice by releasing the gas that will trap him as well.

OK you can all take off your
Mh. Question: the trays in the Mortuary - do they kind of seal of the bodys from the environment? If so, and it looks like that, the gas and the haze evaporate from the dead bodys which were affected by the zombie-agent. It seems to be like a bio-chemical or chemical process going on, although the body of the dead zombie is disfunctional. Unless the zombie-agent is no bacteria, germ or fungus - I think it is neither, but more kind of a chemical cocktail of sorts -, which would survive in an enclosed, almost sealed off, probably kind of cool location, the zombie-agent dissolves the body and releases the gases.

Now, I guess, we need to consider one important detail: from what I understand from Michael's, Victor's and R2Da2's observation, the zombies seemed to have modified/ fortified/ secured the structure of their tunnels with kind of organic stuff - most likely the remains of the dead people and zombies. What, if they used a huge amount of zombie-flesh for this task in the area of Inglewood? Considering the amount of likely zombie-bodies available that would explain why the haze was there for at least three seasons. In season #4 the zombies might have proceded with this task another time (new Little One breeds gone wrong and recycled to become part of the wall of flesh), which let a new haze reappear when Tanya and Victor showed up for some air-samples at ground zero.

Granted: If the zombies have done something like that, the tunnels must have been filled with those gases a lot. Yes. But with those cracks in the ground at Inglewood the gases could dissipate easily - especially, if there are enough open gaps in the system if the tunnels.

Ok. Granted #2: them zombies seem to be affected by the gases as well. Why would they put themselves at such a risk? Good question, which is to be countered by another one: why did the zombies carry away their dead like afrer their war? Their dead bodies had to serve another purpose. Maybe food. Maybe becoming part of the tunnel-system. Maybe becoming a super zombie-gas-chemical bomb underneath LA ...

Best wishes.
