Natural sources of methane include wetlands, termites, decomposing organic materials in ocean and fresh water, and methane hydrate. Anthropogenic influenced sources include livestock flatulence, rice paddies, biomass burning, landfills, coal mining, and gas production, with rice paddies and livestock flatulence being the major sources of methane.
