“Could Less Gassy Livestock Be a Cash Cow?”

It’s time to have a conversation about flatulent cows.

The hamburgers and cheese that come from U.S. cattle may be favorite fare at many summer cookouts, but the methane the same cows produce is significantly less appetizing.

That’s especially the case for sustainable investors looking for a low-emission place to park their cash. “Enteric fermentation,” or livestock’s digestive process, accounts for 22 percent of all U.S. methane emissions, and the manure they produce makes up 8 percent more, according to the U.S. Environmental Protection Agency.

And although agriculture is a growing industry as the world looks to feed its swelling population, some investors are reluctant to support a sector with such a hefty methane footprint.

“Kangaroo flatulence research points to new climate change strategy for farmers”

New analysis of kangaroo farts suggests their low methane levels could have implications for farmers in the fight against climate change.

It has long been known that kangaroos – unlike sheep and cattle – produce little of the potent greenhouse gas methane.

For some time, researchers intent on breeding less windy flocks and herds hypothesised kangaroos might have a unique mix of micro-organisms in their stomachs that produce less of the gas.

The most infamous and abundant greenhouse gas is carbon dioxide. But though less prolific, methane actually packs a meaner climate-warming punch.

To the dismay of climate scientists (and anyone concerned by global warming), there appears to a new and growing source of methane — the deep sea.

Russian scientists have determined that a massive crater discovered in a remote part of Siberia was probably caused by thawing permafrost.

Rising temperatures could have allowed the permafrost to thaw and collapse, releasing the methane previously trapped by the subterranean ice.

“Ruminomics: The Science of Low Emitting Cattle”

Jan. 10, 2014 — A new research project looks into the possibilities of adapting every aspect of cattle husbandry and selection processes to lower their greenhouse gas emissions.

Methane from cows — a greenhouse gas 25 times more powerful than carbon dioxide — makes up 20% of greenhouse emissions from agriculture, or about 1% of all anthropogenic greenhouse gases. That’s according to Phil Garnsworthy, professor of dairy science at the University of Nottingham in the UK. He is also one of the project scientists of an EU-funded research project, called Ruminomics, which is using cutting-edge science to reduce greenhouse gas emissions from cattle.(link)

Different genetic strains of cow emit different amounts of methane. “There are three issues: diet, genetics, and the microbiology of the cow’s rumen. We think that animal genetics may well influence their gut microbiology. However, this link has not been proved and we are still in the data collection phase,”……

If one “ruminates” long enough over the implications of the “genetics issue”, one can imagine genetically modified cows as a neat solution. Choose your poison.
