In the livestock industry, herbivorous mammals, such as cattle, sheep, goats and camels, generate large amounts of CH4 during their normal digestive processes.
CH4 from the animals' faeces is released into the atmosphere
Stored animal manure also generates CH4
Since people keep these animals primarily for food, these CH4 emissions are considered human related
Rice plantations, where rice grows in flooded fields, also release CH4 into the atmosphere
Globally, the agricultural sectors are the primary source of CH4 emissions
