As fun as "a massive sphere of infinitely expanding ticks dwarfing out all light" sounds, we unfortunately cannot have more ticks than the biomass needed to support them, including their own. Also, this kind of assumes an infinite supply of cows/people/other juicy critters, which brings its own problemas.

ok so we can stop this tick threat in its tracks if we just kill everyone and everything first.
