Dean Koontz?
I don’t know cause I don’t remember the author either.
It was not a work of fiction.
It was someone looking at the way things were going and extrapolating out the pretty obvious conclusion. I thought the title was something like *The Coming Apocalypse* but I tried looking it up and that wasn’t it.
It would definitely been written off as conspiracy theory territory but it seemed feasible enough for me to remember it.
