Researchers are working on a way to dramatically reduce the methane gas that cows burp out, in the hope that it can help mitigate global warming.
The National Agriculture and Food Research Organization (NARO) is developing technology to constantly monitor microorganisms in cattle’s stomachs as well as feed to suppress the functions of methane-producing bacteria.
The research organization, which is affiliated with the agriculture ministry, aims to cut the amount of methane cattle emit by 80 percent by 2050.
Methane has 25 times more of a heat-trapping greenhouse effect than carbon dioxide. Cow burps and farts account for more than 10 percent of greenhouse gases emitted in the agriculture, forestry and fisheries industries, according to the agriculture ministry.
