There is always a catch with AGW “solutions”
Most attempts to tackle climate change focus on cutting greenhouse gases from cars and factories, but a small group of scientists think the key may lie in cutting emissions of a different kind.
Methane produced by livestock farming accounts for around 18 per cent of global greenhouse gas emissions in the form of flatulence and belching, according to official estimates.
But researchers at Aarhus University in Denmark believe they may be able to reduce this by feeding cos oregano to alter the balance of bacteria in their digestive systems.
Methane produced from cows is 21 times more harmful to the atmosphere than carbon dioxide. With the demand for milk and steak showing no sign of slowing, this problem can only get worse.
They think the essential oils from the herb, and its potent antimicrobial properties, will kill off the bacteria growing in cows stomachs that emit methane.
Dr Kai Grevsen, a senior researcher involved in the project, told NPR: ‘Oregano has essential oils with a mild antimicrobial called carvacrol, which can kill some of the bacteria in the cow’s rumen that produce methane.
‘Of course, you can’t kill all of the bacteria, or the cow would die.’
I wonder if you make spaghetti sauce with ground beef from cows who have eaten a lot of oregano … can you skip adding oregano?
