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.

A puffy pink seaweed that can stop cows from burping out methane is being primed for mass farming by Australian researchers.

https://www.goodnewsnetwork.org/gamechanging-pink-seaweed-reduces-cow-emissions/

“If we’re able to work out how to scale up the seaweed to such a level to that can feed all of the cows and the sheep and the goats around the world, then it’s going to have a huge impact on the climate; it’s going to address a whole lot of carbon-neutral agendas that different countries have; and it’s ultimately going to save us all billions of dollars,” he concluded.

Maybe has potential, but it's been kicking around for quite a while with seemingly little traction. Why? Can it be done without reducing production?

Are there any issues with heavy metals such as Mercury in the ocean water? I heard that it gets concentrated in predator fish to the point where pregnant or lactating women should avoid eating it.

Why Buy the Cow When You Can Biofabricate the Milk for Free?

Move Over, Fake Meat—Cow-Less Milk and Cheese Are On the Way
https://about.bgov.com/news/move-over-fake-meat-cow-less-milk-and-cheese-are-on-the-way/

Dairy tastes like dairy thanks to two key proteins, casein and whey protein. Researchers at several start-up companies have begun producing these proteins in the lab, with the aim of creating a new grocery store category: cow-free dairy.

Their process is loosely comparable to the way Impossible Foods or Beyond Meat makes meatless burgers. Microbes, such as yeast, are given the genetic instructions to produce the dairy proteins. The microbes are then cultivated en masse, with nutrients added and the temperature adjusted. Eventually the organisms start churning out large quantities of the proteins, and these are isolated and added to various recipes.



Hundreds of thousands of metric tons of whey and casein are consumed in the United States each year, virtually all of it produced by dairy farms. Proponents of lab-made milk see the product appealing to dairy lovers broadly, while satisfying concerns about animal welfare and environmental sustainability. But to make a real impact on the planet, and eliminate the carbon emissions from all those belching cows, a great many microbes will need to be corralled.

... Perfect Day (originally Muufri), may be the furthest along in perfecting a recipe for lab-made dairy. The company produces whey protein and mixes them with other ingredients found in traditional dairy — fats, carbohydrates, calcium and phosphates. In early July, a limited-edition ice-cream batch was released, with flavors including chocolate, vanilla salted fudge and vanilla blackberry toffee; it quickly sold out.

... The dairy substitute is nutritionally identical to cow’s milk and tastes just like it. In fact, while Perfect Day Foods at least considers its product “vegan” and lactose-free (since lactose is a sugar found only in mammals’ milk), federal law actually requires them to put “contains milk” on any labeling because its protein is identical to cow’s milk on a molecular level and could cause allergies.

The challenge is scaling up. Perfect Day plans to sell its lab-made whey to ice cream-makers, dairy companies and restaurants rather than directly to consumers. It has also partnered with agriculture giant Archer Daniels Midland, with its industrial-scale fermentation infrastructure, to try to meet market demand and reduce the cost of producing proteins.

Perfect Day co-founders Ryan Pandya and Perumal Gandhi, who started the company in 2014, said they were eager to produce a product that could make a “sizable impact” on factory farming, unlike the pace of plant-based companies.

These artificial meats and milks truly horrify me. Reminds me of the 60s when doctors told mothers that they need to breastfeed their children only for at most 6 weeks, since their "formulas" are much better than the real thing, ie. mother's milk. Turns out, children that got the real thing are healthier, live longer and more mentally stable than the others, who got  artificial mother's milk...what's next, make fruits and veggies in the lab? Thank you, but I'll choose the real thing

Oktoberfest 'Produces 10 Times as Much Methane as Boston'
https://www.theguardian.com/environment/2019/oct/27/oktoberfest-munich-methane-emissions-environment

Researchers at Technical University in Munich walked and cycled around the perimeter of the festival last year with mobile sensors aloft. The instruments found the event emitted nearly 1,500kg of methane – 10 times the amount that wafted off Boston, Massachusetts, in the same period.

The scientists attributed most of Oktoberfest’s emissions to leaks and incomplete combustion in cooking and heating appliances. Though an appreciable part of the rise in the gas, about 10%, was attributed to the flatulence and burps of attendees.

Jia Chen, who studies greenhouse gases in urban environments, said: “The observed methane concentrations cannot solely be explained by biogenic sources.

Sorry to be an alarmist but the problem I see with growing seaweed on a massive scale might be that toxic matter, or even radioactive materials, might be absorbed by the seaweed and then cattle.

With the release of radioisotopes from Fukushima, even eating fish might be an issue.

Villabolo, You are spreading Misinformation. You should always try to source your own BS. Here is a report on radiation, Fukushima, and seafood samples.
https://www.doh.wa.gov/CommunityandEnvironment/Radiation/FukushimaUpdate/FishandShellfishTesting

Although I would think kelp might actually have higher levels especially from waters near Fukushima the kelp that produces less cow farts grows in more tropical areas like Hawaii. And people eating the kelp is likely a larger concern than Cows?

<snippy>

Burping methane? Cows do that, but humans?
I drink much beer which contains CO₂, so that's what I'm burping ain't I?
Eating a lot of bradwurst may be the reason for methane flatulence.
Burping and breaking wind are two human means of expression that are undervalued :).

--

Concerning the thread title, we should leave the cows alone, have some respect. Organic farming emits less methane because of what the cows eat. This methane problem is likely caused by feeding cows soya, sourced from the amazon. And the cows given antibiotics and growth-hormones which also likely adds to the methane problem. Intensive agriculture is also responsible for deforestation, habitat loss, 'wild' fires, mono-culture grasslands, showers of biocides, artificial fertilizer and a very unnatural life for all animals involved.
This thread's title lets us view the world through a callous intensive farming industry's window. Break the bubble!

As a follow-up from my previous post, about intensive agriculture. Not methane but nitrous oxide focus. To show that it is the callous and destructive system of intensive agriculture and not farming per se e.g. organic farming, permaculture farming and agroforestry.

https://www.theguardian.com/environment/2020/oct/07/intensive-farming-worldwide-threatens-paris-climate-accord-report-says
  by Fiona Harvey

Intensive farming worldwide threatens Paris climate accord, report says

 Excerpt:

Nitrous oxide is given off by the overuse of artificial fertilisers, and by organic sources such as animal manure, and has a heating effect 300 times that of carbon dioxide. Levels of nitrous oxide in the atmosphere are 20% higher than in pre-industrial times, with most of that increase coming from farming.
