I do think that people have a limit as to how many things they can loudly and truly care about.
For me, it was how we treat indigenous peoples in Canada. Then Ukraine, and Palestine.
And now? We're a bit overwhelmed with the one country who has the most power in the world and wants to start WW3.
I think it's human also? We're all a bit selfish. Doesn't mean we forget our own shortcomings.
