Ask HN: What pressing world problems should a graphic designer work on?

I went through the 80,000 hours (https://80000hours.org) course and felt inspired to do work that matters (rather than just design some stuff for boring corporate companies). As a designer, what would be a pressing problem that I could work on and potentially even get compensated for the work in order to stick with it and pay the bills (so helping out a nonprofit with design might be fun, but it's not sustainable)
