Fish oils reduce greenhouse gas emissions from flatulent cows
Omega 3 fatty acids in fish oils can improve meat quality and reducing methane emissions in cows. Methane given off by farm animals is a major contribution to greenhouse gas levels. Researchers from University College Dublin reported that by including 2 percent fish oil in the diet of cattle they achieved a reduction in the amount of methane released by the animals.

Combined nutrients and warming massively increase methane emissions from lakes
Shallow lakes in agricultural landscapes will emit significantly greater amounts of methane, mostly in the form of bubbles (ebullition) in a warmer world, which is a potential positive feedback mechanism to climate warming. Submerged plants are key predictors of methane ebullition. The combination of warming with the loss of plants appears to transform shallow lakes into methane bubbling machines. (2018-01-22)

Paired microbes eliminate methane using sulfur pathway
Anaerobic microbes in the Earth's oceans consume 90 percent of the methane produced by methane hydrates -- methane trapped in ice -- preventing large amounts of methane from reaching the atmosphere. Researchers now have evidence that the two microbes that accomplish this feat do not simply reverse the way methane-producing microbes work, but use a sulfur compound instead. (2008-01-17)

Researchers in Spain propose mitigating methane production by dairy cattle through breeding. In an article appearing in the Journal of Dairy Science, scientists are targeting reduction of enteric methane in the breeding objectives for dairy cattle to select for animals that use feed more efficiently and thus produce less methane. Because livestock farming contributes 13 percent of global greenhouse gas (GHG) emissions, selective breeding can reduce those emissions while increasing milk output. (2020-07-22)
