I'm with you on the dangers of all these things, but I'm going to disagree that they're civilization reset events - although they could spark one. A massive global famine could kill a billion humans or more. But if the 1 in 10 of us (likely the poorest, most vulnerable people) died, would civilization end? I don't think so. However, if that leads to all out nuclear war, then we have two enormous correlated shocks to the system. Maybe even that wouldn't be enough, but some number of such shocks could push us over the brink. Just like an economic meltdown or a plane crash, it's never one thing that goes wrong, it's a sequence of failures.
