Methane is a colorless, odorless gas that is the main component of natural gas. It is also produced in the digestive system of animals, including humans, and is released through flatulence. Farting is a normal part of digestion and is usually caused by swallowed air or the breakdown of certain foods in the large intestine. While most of the gas released is odorless, some contain sulfur-containing compounds, such as hydrogen sulfide, which can give a person's fart an unpleasant smell.
