Interesting idea Tenmei.
Here's a reworking of the plot: the powerful airborn toxin the replicators emit is a neurotoxin that doesn't outright kill you. Instead it makes you kill yourself and this effect can only be activated by a certain level of lifeform-emitted biochemical elements in the air, in other words it's only triggered when large groups of people are present.
We can call this new Trek series...Star Trek: The Happening! LOL
