Every problem of this modern age is directly related to overpopulation.
Yet I still haven't heard a politician call for a drastic reduction in population.

So at this point, our political institutions have chosen to ignore the problem, or to talk around the problem, which means that the problem isn't to the point where it's a big enough problem to generate a meaningful response yet.
