Explanation:

Methane is an odorless, colorless greenhouse gas with the chemical formula of CH4. It is mainly used as a component of natural gas.

Natural sources create 36% of global methane emissions, long before humans existed there has been methane emissions into the atmosphere. However, methane expulsion is mainly man-made, in activities such as landfills and livestock farming. As a fact, it may seem interesting to know that daily methane emissions from cows (through belching and flatulence) and from cars are pretty similar.
