When someone cuts a good one in a crowded elevator or bus, the
waft can be almost suffocating. For hundreds of cattle on long
voyages across the globe, such gassy emissions have been
lethal. Cows fart themselves to death by emitting fatally high
levels of ammonia during the lengthy trips. In the cramped,
hot and poorly ventilated cattle holds, the ammonia-rich gas
can quickly cause respiratory problems and death. A cause for
concern was raised last year when one voyage found fatalities
to 900 cows. So, next time you have to let one rip in a small,
crowded area, try to hold it in; you could be saving lives.
