Seaweed found that eliminates cow methane release.
« on: November 20, 2016, 10:50:21 PM »
"A P.E.I. farmer has helped lead to a researcher's discovery of an unlikely weapon in the battle against global warming: a seaweed that nearly eliminates the destructive methane content of cow burps and farts."

http://www.cbc.ca/news/canada/prince-edward-island/pei-cow-farting-1.3856202

"Ruminant animals are responsible for roughly 20 per cent of greenhouse gas emissions globally, so it's not a small number," said Kinley, an agricultural research scientist now working at the Commonwealth Scientific and Industrial Research Organisation in Queensland, Australia.

"We're talking numbers equivalent to hundreds of millions of cars."

Kinley thinks it could take anywhere from three to five years to get a commercial animal feed to market. He says the biggest challenge will be growing enough seaweed.

"Agriculture stands to be one of the first to make major changes in the greenhouse gas inventory and so it's really a game changer if we can get this out into the market."

Morganism, I looked up the kelp ( Asparagopsis Taxiform ) mentioned in the above linked article.
I found another paper that seems to validate the claims about kelp additions to cattle feed eliminating methane production. Only two percent by weight required as a feed additive to achieve methane elimination.

I was asked recently about where a philanthropist might direct some money to directly address  climate change. Not education or research but boots on the ground mitigation. I wasn't able to immediately give any advice. Changing the methane production of cattle might fit the bill.

Turns out, California just passed a law requiring a reduction in cow farts, so sent a link on to the website contact at bottom of this page. They had no method to induce this reduction, so maybe we will see some action there....

I'll follow this story with interest - and some skepticism.

The first linked article mentions a 20% reduction - that's nowhere near a effective as giving up beeef and dairy. 80% ruminants are still a disaster.

This sounds encouraging

However, it's not been tried "in vitro".

Perhaps in years ahead (how many years?) humans will be able to consume beef and dairy and not screw the climate. Until that happens let's do the decent think and kill all the cows and eat them now.

Looks like California really is following up on the seaweed method, they are running an experiment with controls !

https://e360.yale.edu/features/how-eating-seaweed-can-help-cows-to-belch-less-methane

"The results have exceeded everyone’s expectations, including Kebreab’s. His three-month study of Ginger and her cohort found that spiking cows’ ordinary rations with one kind of marine macroalgae in particular, Asparagopsis, reduces enteric methane by 58 percent. More than other seaweeds, Asparagopsis contains compounds that inhibit the production of methane, or CH4, and interrupt the process by which carbon and hydrogen bind together.

“We did not expect these numbers in the doses we used,” Kebreab says. Milk production held steady or increased. A panel of tasters detected no differences among the different cows’ milk."

cross post update with " seaweed and seashell farming"
https://forum.arctic-sea-ice.net/index.php/topic,2275.msg161916.html#msg161916

update:

The race is on to cultivate a seaweed that slashes greenhouse emission from cows, other livestock

"Salwen said that while there's some competition to develop cultivation techniques of Asparagopsis, people are largely working together to share information and best practices. She said that those involved see significant room for many different players in what could be a massive new industry.

"This will be like growing corn or soybeans," she said. "There will be a whole lot of people cultivating and building farms. It's not like anyone believes for a second that they could own the production market, so people are really collaborating."

this might be a excellent reason to build the major water pipeline they talked about a few years ago.
they were discussing taking the winter flood waters from the upper midwest, and pipe-lining it down to the farming country above the Oolagalla reservoir, to recharge the groundwater in winter, and water plants in summer.

It would make some sense to have a saltwater pipeline to the upper midwest, to raise the seaweed in, and then use as a fertilizer and nutrient additive, rather than trucking it in. Turns out, a little bit of seawater is a great way to renew the nutrients that are leached from the soil.

"All SeaAgri products are produced from the Sea of Cortez containing 92 minerals and trace elements, plus more than 50,000 organic compounds. Scientific data shows that SEA-90’s minerals and trace elements stimulate, feed and enhance micro flora populations in soil, and as little as one ounce of SEA-90 Essential Elements provide nearly complete mineral nutrition."

Thousands of miles of saltwater pipelines?  Water is heavy stuff, and it's costly to pump.  Much better to grow seaweed in the sea, and move the dried seaweed by rail.  No need to transport all the excess salt and water.

Most sea life requires an extremely stable environment.  Ever try to keep saltwater fish in an aquarium? Tiny variations in temp, pH, ions and you've got dead fish.  I doubt the plants are much more resilient.

Seawater minerals are probably great, but most crops have a very low tolerance for sodium chloride.  Many acres have been lost due to tiny levels of salt in irrigation water.
