Flatulence Facts by Flat-D

Farts are produced by anaerobic (without oxygen) digestion in the intestine. About 1% of flatulence is composed of malodorous, volatile sulfur gases, derived from the decomposition of protein. The proteins in meat and some vegetables (e.g., beans) are rich in sulfur-containing amino acids, and so produce stinky farts.
The average fart contains about 7% of the odorless but flammable gas known as methane—the subject of this week’s blog. Namely, rising concentrations of methane in the atmosphere are often recognized as a cause of global warming, and methane is at least 25 times more effective than carbon dioxide in effecting climate change in the atmosphere
