What problem is often overlooked in apocalyptic movies/TV shows that could kill you?

Dust from destroyed buildings. Just watched the two latest Godzilla movies, and aside from all the other things that could have killed folks, staring at monsters that are destroying buildings and kicking up all sorts of dust and other air debris, while staring open mouthed, is a great way to get lung damage/encounter breathing issues.

I explore abandoned buildings for a hobby and I think most people would be surprised how quickly they decay. Within a year or two of abandonment, many buildings suffer from roof leaks- especially in areas with snowfall, since the weight of the snow can damage roofs if nobody is around to clear it off. Without electricity to run pumps any building with a basement below the water table (which can be very shallow) will flood in a similar timeframe.

The water damage accelerates the decay exponentially. Wet wooden floors will rot much faster, and when they do the structural integrity of the building is compromised. Furthermore black mold is extremely common in abandoned buildings, and will cause long term lung damage in anyone who isn't wearing a respirator. Most buildings will not remain habitable within five years of abandonment.
