Why do gas cooktops need a downdraft?

Gas cooktops either need a downdraft or an updraft. Either way, it's intended to remove harmful gas fumes from inside the home. Allowing the gas to remain in the home would subject all occupants to possible death or severe injury from carbon monoxide poisoning.
