There are also lakes which occasionally emit big bursts of CO₂. And, of course, it's denser than air, so you get an invisible flood of CO₂ pouring down the riverway... where people live. These can be thoroughly fatal.
Lake Nyos emitted a CO₂ cloud in 1986 which killed 1700 people.

Kind of a nice way to go, actually. https://en.wikipedia.org/wiki/Inert_gas_asphyxiation https://en.wikipedia.org/wiki/Inert_gas_asphyxiation
