Some volcanic vents leaking out of a nearby lake, producing a layer of poisonous gas for miles around would do this. There are areas like that currently. There were likely many more way back then.

He said slight change.
I don’t think a slight change in CO2 would do it.

Lake Nyos, in Cameroon, seems to have done just that in 1986. 1,700 died, thousands of livestock, as well.

Read a story of a big belch of CO2 or methane from the bottom of a lake wiped out a whole village.

all of them were found clustered together around what was then a watering hole.
Perhaps it was some naturally occurring toxin that contaminated the water, poisoning all of them.
