But the concentration of methane in the atmosphere has almost tripled
in the last 150 years, mainly through human-influenced so-called
biogenic sources such as the rise in rice cultivation or numbers of
flatulent ruminating animals. According to previous estimates, these
sources make up two-thirds of the 600m tonnes worldwide annual methane
production.

CB; I wonder if humans are a significant portion of the flatulent ruminating
animals.
