Like the other comment said, it’s never specifically mentioned. The event or catalyst isn’t the point of the story so I don’t think McCarthy intended to spend much time on those particulars.
I need to re-watch it but from what I remember the man goes through the entire story with a ever-worsening cough, the air quality isn’t great, there’s not much sunlight that comes through anymore, hence plants & whatnot pretty much all die off. I didn’t quite follow why there’s no more electricity/power anymore but that happens too. Taking a guess McCarthy is vaguely describing something similar to a catastrophic asteroid event or a major volcanic eruption along with a massive solar storm or something along those lines.
Coincidentally I just watched Greenland 2 (sequel to Greenland, obvs) which is about an comet/asteroid event and the aftermath. Neither movie is nearly as good as The Road but they’re fun popcorn movies if you’re into that sort of thing… the second movie definitely gets some inspiration from The Road, I’ll say that much. Not nearly as bleak.




A bit gross. Even more so if the woman is not welcoming to that sort of thing. …OTOH to be fair if they are both into it then okay it’s between those two.
That exact situation has happened at the building I work in, older 50’s maintenance guy keeps calling out to and trying to have conversations with my early 20’s coworker. She finds it extra gross that the married guy has a daughter about her age. At one point she got stuck riding the elevator with the guy and he tried touching/grabbing her shoulder and she noped out of there as soon as the elevator opened. At this point pretty much everyone at my work area knows about it and warns her whenever he is around so she just kind of avoids/hides from the guy.
What I find interesting is when older guys exhibit that sort of behavior, do they think it’s just private between the two of them? Younger women like to talk and they definitely will talk about this stuff to friends/coworkers.
