It's a silent, but possibly deadly, problem.
Feeling guilty about their country's greenhouse-gas emissions, New Zealand scientists want to squelch the biggest source: livestock flatulence.
Methane pumped out the backsides of New Zealand's 45 million sheep and 10 million cattle helps make the tiny country a bigger per-capita climate culprit than notoriously polluted China, reports the Times of London.
So it was with great pride Wednesday that Phil Goff, the Kiwi trade minister, told a Paris meeting of the Organization for Economic Co-Operation and Development that the genome of the microbe responsible for all that methane had been isolated.
That would pave the way for a vaccine against bovine flatulence, he added, according to the Daily Telegraph.
