Methane is a chemical substance CH<sub>4</sub> found in a high percentage in [[natural gas]]. It is also produced through natural processes from the decompostion products of animals.
'''Methane''' ('''CH<sub>4</sub>''') is a [[chemical]] substance found in a high percentage in [[natural gas]]. It is also a common byproduct of [[digestion]] in humans and [[animal]]s. It is also known as "marsh gas" or "swamp gas" because it is produced when vegetation decomposes in water. Methane is lighter than air and is extremely volatile. It tends to dissipate quickly, but a large enough concentration can displace breathable air. Methane is an important constituent of [[natural gas]].
==Safety and health==
Naturally colorless and odorless, methane is deadly in high concentrations and is one of the "[[greenhouse gas]]es".
==References==
A tragic example of how deadly methane is occurred on July 2, 2007, when a [[Mennonite]] farmer climbed into a manure pit to fix an unclogged pipe. Unbeknown to him, methane gas existed in that pit and it almost instantly killed him. A farm hand, also unaware of the existence of the methane gas, rushed in to help the farmer and then immediately died himself. The farmer's wife and two of his daughters rushed in to help; they inhaled the methane gas and also died immediately.<ref>http://www.chron.com/CDA/archives/archive.mpl?id=2007_4378567</ref>
==Occurrence==
Methane is found in high quantities in the outer regions of the solar system; it is a major component of [[Jupiter]] and [[Saturn]], and is found frozen on [[Pluto]]. It is also found in the [[comet]]s and [[asteroid]]s of the [[Oort cloud]].
