As an experiment, here's a thread for people to post about things they care about. Specifically, for things that are possible to contribute to, in some way, and preferably, to invite others to join.
Mine is buying and donating highschool textbooks to schools in the 'grey zone' of Ukraine (where the war kinda isn't fought, but few people would be surprised if it started.) I don't deliver them myself, though.
What's yours?
Maybe starting the Church of the Frost Giants and declaring cryonic suspension to be a religiously mandated funerary practice would work to that end.
I think actually reviving some ice mice might be a bigger step, though.
