Context
Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from livestock and other agricultural practices, land use and by the decay of organic waste in municipal solid waste landfills. Methane is the second most important greenhouse gas. It is more potent than CO2 because the radiative forcing produced per molecule is greater. In addition, the infrared window is less saturated in the range of wavelengths of radiation absorbed by Methane, so more molecules may fill in the region. However, it exists in far lower concentrations than CO2 in the atmosphere, and its concentrations by volume in the atmosphere are generally measured in parts per billion (ppb) rather than ppm. Methane also has a considerably shorter residence time in the atmosphere than CO2 (the residence time for Methane is roughly 10 years, compared with hundreds of years for CO2)

Inspiration
Everybody talks about Carbon Dioxide when it comes to GHG (greenhouse gases), however we need consider the 2nd most GHG which is a direct result of livestock farming.
