Are we, really? Which mass extinction events would those be, and in what way do "we" trigger them in the name of improving things? To me it sounds like you've been exposed to a bit too much agit-prop that the discovery of a potential natural therapeutic (not manipulated, just regular old bacteria) against tumours evokes such a response.
Certainly lots could be said here, but first and foremost its more than a little weird to be so fixated on that Greta girl like this.. You should really, like, work on making your point without bringing her up maybe? Maybe try writing two sentences not talking about her and go from there? I am not sure you appreciate how much it takes away from you point... Like, oh no, are you going to say something bad about Al Gore next? I will be devestated...
While we are at it: whats with the antiquated parlance? Are we playing DnD right now?
