Crazy how thin the line is between society as usual and total melt down. Makes you really appreciate yow fragile all of this is. Growing up you think the way things are is how they've always been and always will be.
I wouldn't talk about a meltdown of society here - this is a natural disaster, not the sacking of Rome. In due time help will arrive, people will bury the dead and rebuild. Though I agree it makes you appreciate how we take things for granted until one day they aren't.
Climate change caused this so I don't know that you can really call it natural. Unless you include things people do as natural (I tend to but that's not how most people use the word.)
I always thought it was a little arrogant of us humans to assume if we created something, or cause something to happen, that it isn't considered part of the natural world. Like, of course it is. As you said, anthills are natural, beaver dams are natural, so skyscrapers are just as natural as a bird's nest.
....yet. looks at record breaking forest fires in Canada. Yes I know it'll take a lot more to have a drastic impact but we've been neglecting our impact so it's just a matter of time.
