At Part11, otherwise, there would some persons who could not unserstand next part.

Time’s only one directional nature from past to present into future(if we make our consciousness at present), to it, suppose that we could make it changed, if that law was overturned arbitrarily, we’d be able to escape from sizably smaller creature’s harm to us completely, because as well as our human’s war battle, we’d exterminate them perfectly, nevertheless we’d never do so, though we expediently use insecticide or so for emergently makeshift measure in embodiment.

This time only for analyzing only upper part could advance.
Though. if you understood all I wanted to claim only with Part11, this Part12 is not necessary at daringly reading.

The first what we clearize is "what makes us desperate?"
And its answer is very simply easy to see to us.

First, what we use e.g. insecticide to harmful insect is derived from what we know that it is just expediently emergent method to sweep them away from each "now"'s annoyable situation.
Because using them must reason that we could get rid of any distracted situation caused from ants, bees, mosquitos, leeches, gnats, flies, fleas, lice, white ants, cockroaches or so.
Nevertheless, we know that we must not exterminate them all so perfectly.

That reson is either caused from that we know ecosystematic order including food chain, commensalism, and mutualism in regard of mechanism.
Necessarily to us, harmful, injurious insects vermin or so, we must never be able to have only mutualism, in terms of rationalism and mentalism, necessarily with minimal prevention never making them to approach our civilization, thus occasionally ultimately complete extermination as large scale strategy gets to be necessary. Nevertheless we know that even these are just temporary transaction.
These the most convincing reasons are convincing only through our knowledge that their threat could be prevented by out notice, and all we have to guard our life, its extermination could be extremely costing action for our society.

Meanwhile, if their presence at assaulting our civilization, we'd absolutely embark on complete extermination even if it'd be one of their territory or survival zone, or mainly prosperous domain.
And to smaller sizable presence, we'd not have so desperate transaction, that reason is what we could prevent us from harmed by them with our care, attention and minimally guard to our skin or so.

However, if we freely change our own size according to them as those referred objects with injurious insects, we must temporarily try to switch our size. Because that option must be advantageous to win them.
Because the presence of which condition as size is the same must have the same survival zone, and that must be come under our human world's war battle among the same species.

Though, e.g. at the world war second, US army tempting governmental slogan "Remember Pearl Harbor!" and Japan army doing governmental slogan "Kichiku-Bei/Ei!" could be made.

Those all upper described truth must be relevant with the issue of the same zone sharing fact as desperate thorough war battling. Nevertheless, actually we as human society and e.g. mosquito's society are mutually obviously differentiated zone's share as the genuine implicit mutual undestanding that complition of extermination costs so much, never yet that act is critically affecting even our civilization.

If we try to summarize all these lodical processes, one very cardinal and critically crucial truth must make itself visibly outstanding.
To us, at any rate, only costing issue, with cost performance and issue of burden at calculating our accountable advantage's index must come up to us. Because only that smart deal and solution must provide our civilization maximal advantage.

Memorandum; This time, I daringly implied ultimate surival option. Exactly, at a glance, that stance could be seen so genuinely overwhelming exaggeration.
However, we could never be desperate at breaking through everything, and without that mode, we'd never output any credible index at sustainable reference. This time's COVID pandemic crisis overshadowing our reality is the same.
