Cow belches and farts are a major source of greenhouse gases that affect climate change even more than vehicle emissions. A new type of cattle feed that is supplemented with oregano, developed by a dairy scientist, could help reduce cow gas emissions by 40%. It also improves milk production.
PhysOrg.com quotes its inventor, Alexander Hristov, as saying, “Cattle are actually a major producer of methane gas and methane is a significant greenhouse gas. In fact, worldwide, livestock emits 37% of anthropogenic methane.” (Anthropegenic methane is methane produced by human activities, such as agriculture). And methane has 23 times the global warming potential of carbon dioxide. [Thus] “any cut in the methane emissions would be beneficial.”
