Limestone is a common type of sedimentary rock which I find uncommonly interesting! It's mostly calcium carbonate, which is also what eggshells 🥚, seashells 🐚, and pearls 🦪 are made out of.
In places where it rains a lot, limestone erodes easily, which results in simply gorgeous landscapes such as:
Hạ Long Bay in Vietnam
Tsingy de Bemaraha National Park in Madagascar
The Li River in China
Additionally, the world's longest (Mammoth) and deepest (~~Veryovkina~~ Krubera is once again the world's deepest cave, thank you to SockOlm for pointing that out) cave systems are both found in limestone formations
Mammoth Cave in the United States
Veryovkina Cave in Georgia/Abkhazia/Russia (disputed territory)

I've been thinking about RuPaul's Drag race recently and basically 2 points that might be connected or coincidence.
Firstly you never fucking hear Cishets talking about it anymore. Like a few years back it was a thing they would always bring up when someone was gay or trans (unfortunately). Despite it being on it's 17th season and having like 20 something international spin-offs. Like that's not necessarily a bad thing, except...
Secondly the show has done a real 180 on how shitty and transphobic it was. RuPaul still sucks for fracking and other reasons (but he's only on like 3 of the shows, and no one watches to see him phone it in each week), but he's basically recanted most of the transphobic shit he said. Each season has multiple trans women or non binary performers, even one trans man has competed. The top finalists of later seasons are frequently trans, several trans women/femmes have won the show (mainline and spin-offs).
The most recent show had enormous representation in Lexi Love who was/is a complete train wreck (but still a top 4 finalist). Drag Race Canada this most recent season had Jaylene Tyme a two-Spirit First Nations and Métis Indigenous trans woman, who was a sixties scoop survivor (Canadian stolen generation equivalent).
It's lib/idealist AF but this quote from Vulture is still pretty true.
And guess circling back around to my first point, the show got better about trans people, and then it sort of dropped off the public's radar.
