> Is this sarcasm? Do you want ‘extra’ life inside your body
Not at all: perfectly serious. We are in a system surrounded by living entities - some innocuous, some threatening, some helpful, some being the threatening food of helpful ones...
Your body already hosts living entities that live with you symbiotic. Some of them have the extremely important role to keep the worse others at bay through geopolitical control (you remove them, the damaging ones have free course...).
There are many more things around you than «tapeworms and other parasites». And they could be active part of a system (which could get unbalanced without a part).
So: before stating e.g. that all other life (e.g. in the air) should be wiped out, an intellectual inquiry about the model must be given. You do not embrace what superficially sounds like a good idea.
Is this sarcasm? Do you want ‘extra’ life inside your body, like tapeworms and other parasites?
