I read this fanfic once that speculates that Grimm are born from dead flesh without Aura to supress them. Because of that, it's basically impossible to control their numbers, and that humanity, if no solution is found, will eventually lose against them. Don't know if in-universe a similar process is there but it's not a bad hypothesis
