These observations imply that the quantification of present-day gas emissions in the Arctic may be underestimated.
Can Seaweed Cut Methane Emissions on Dairy Farms?
Expert Sees Dramatic Reduction When Cows Consume Seaweed Supplement by Diane J. Nelson | May 24, 2018
Quick Summary
Adding seaweed to cattle feed may significantly reduce methane emissions from dairy cows
Method could help dairy farmers meet new state methane-emissions standards
The UC Davis project is first in the world to test seaweed on live dairy cattle
Seaweed may be the super food dairy cattle need to reduce the amount of methane they burp into the atmosphere. Early results from research at the University of California, Davis, indicate that just a touch of the ocean algae in cattle feed could dramatically cut greenhouse gas emissions from California’s 1.8 million dairy cows.....
......But there is still a lot to learn before farmers should consider feeding cattle seaweed.
“We have much more research to do to determine if seaweed supplements could provide a viable, long-term solution,” Kebreab said. “But we are very encouraged by these early results.”
By far the largest source of methane on this blue planet are the surface dwelling and photosynthetic cyano-bacteria. A new paper in Nature elucidates on the chemistry but the ecology has long been reported. Cyano-bacters are the most abundant life on this planet in both numbers and mass and that they also produce 5 times the amount of methane than land based sources including our anthropogenic methane is vital to understanding the role of ocean pasture life in controlling our climate.
