BELCHING and farting sheep and cattle, blamed by doomsters for driving the planet towards climate catastrophe, may have met their match.
Eructations from farm animals account for a fifth of all global emissions of methane, a greenhouse gas that is less plentiful but far more potent than the most notorious culprit, carbon dioxide (CO2).
Chewing over the problem, scientists at Australia's Commonwealth Scientific and Industrial Research Organisation believe a new vaccine can help protect Earth from the ruminant menace, New Scientist reports.
A vaccine against three species of microbe which produce methane in sheeps' stomachs reduced methane belches by 8 per cent in a 13-hour test.
The formula is only a prototype, for the scientists believe they can wack more of the remaining species of microbe, which together account for 80 per cent of sheep methane, the British weekly reports next Saturday.
