Methane is emitted from which of the following?
(a) Paddy fields only
(b) Termitary only
Correct Answer:
(C)
Methane (CH4) is emitted by natural resources such as wetlands as well as human activities. Natural Resources - Wetlands are the largest source, emitting CH4 from bacteria that decompose organic materials in the absence of oxygen. Smaller sources include termites, oceans, sediments, volcanoes and wildfires.
Human Induced -
Agriculture - Domestic live stocks such as cattle, produce large amounts of CH4. Paddy cultivation and storage of manure in lagoons also releases methane. Globally, the agriculture sector is the primary source of CH4 emission.
Industry - Methane is the primary component of natural gas.
Waste from Home and Businesses - Methane is generated from the decomposition of waste in landfills.
Note: Rice fields, coal mines and domestic animals are human sources of methane emissions in the atmosphere while wetlands and sea hydrates are natural sources of methane emission. Maximum (about 76% of the total methane emission) from natural sources is emitted through the wetland only.
