Your only valid point is that the replacement organisms might be more dangerous to humans. I find your callousness toward human suffering repulsive. If I could press a button that would instantly wipe out any and all animal species which cause human suffering without any negative consequences, I'd do it in a heartbeat.

The animal species that causes the most human suffering is... humans.

(Or were you being facetious? Especially since you shifted the argument from insects to animals.)

[ugh]

I would guess that’s why there is a “without any negative consequences” condition?

If I could, with the push of a button, kill any and all species which cause harm to humans without, in the process, causing harm to or even killing humans I would do it, too. Sure. No second thoughts about that.

Insects are animals.
