"Save the world eat bugs" they say, well it turns out that:
"By weight, cattle do not produce the most methane. Insects do. There are a variety of insects, that also have methanogens in their digestive tracts, that produce methane
(Methanogens are bacteria in the digestive tract that produce methane via fermentation also known as methanogenesis). Cockroaches, termites, centipedes and various arthropods all produce methane as noted in this study from 1994 “
Methane production in terrestrial arthropods.” Roughly 200 to 300 hundred cockroaches emit as much methane as a head of cattle.
If you look back at
articles from the early 1980’s on termites, based on laboratory (in vitro) experiments, many scientists thought termites could be responsible for up to 30% of global methane emissions."
