Australian 'Super Seaweed' Supplement To Reduce Cattle Gas Emissions Wins $1 Million International Prize (abc.net.au) 72

SpamSlapper shares a report from The Australian Broadcasting Corporation: A company commercializing a CSIRO-developed, seaweed feed product, which slashes the amount of greenhouse gases cattle burp and fart into the atmosphere, has won a $1 million international prize for its work reshaping the food system. CSIRO-affiliated company Future Feed said it would use its Food Planet Prize winnings to create an international commercial fund to help First Nations communities generate income from cultivating and selling the seaweed.

Methane emissions from livestock make up around 15 percent of global greenhouse gas emissions, and one cow produces on average as much gas emission as one car. "As a greenhouse gas, methane is about 28 times more potent in terms of global warming potential than carbon dioxide and lasts much longer in the atmosphere," the CSIRO said on its website. Future Feed director and CSIRO scientist Michael Battaglia said that when added to cattle feed, the product, which contains Australian "super seaweed" Asparagopsis, virtually eliminated methane from the animals' bodily emissions. "We know that just a handful [of the product] per animal per day, or 0.2 percent of their diet can virtually eliminate 99.9 percent of methane," Dr Battaglia said.

    If this becomes mainstream , that likely means large scale agricultural farming of seaweed (probable ecocide) the logistics cost of transporting feed to the cattle farms. To think a company won a 1 million award for a product with such a massive oversight does not fill me with confidence that humanity has the intelligence to get us out of this climate catastrophe. We need to end large scale agriculture not stick a band aid on it , creating more ecocide in the process.

        Intensive non monoculture organic gardening can produce dramatically more yield than growing monocultures in gigantic fields. Problem is, those monocultures are necessary for gross machine cultivation, which drastically reduces the labor involved. But if we don't drive ourselves to extinction (or even just technological collapse) first, we will make robots which solve that problem.

        End result, the planet could sustainably support even more people than are here now, if we can just make it that far.

        • Human dietary needs can be sustained through a rather small plot of land, with the appropriate techniques. But yield doesn't tell the whole story; the cost of harvesting can't be ignored. Cost per calories delivered matters. And row crops harvested on a massive scale by machines produce the cheapest calories to humans.

        Option 3 is to reduce poverty and increase the middle-class which naturally brings down birth rates. Evidence of this is Japan and much of Europe. Its the civilized and human alternative.

        there is more land allocated for cattle than used for human habitation.

      K, you try your approach, and they'll try theirs, and we can see which of you is more successful.

    • Any solution to pollution, deforestation, or other "ecocide" that does not create abundance is doomed to fail. Abundance is the key. Until you embrace that you are just burning money to make yourself feel better. In the case of this discovery the abundance-centered solution is to view this as the missing piece to be able to do large scale carbon negative managed intensive grazing de-desertification projects with high-quality high-value food as its waste product. That's a win.

    Bravo, and congratulations!
  • This is the kind of result you get when clever people are presented with a problem and allowed to attempt to solve it.
  • Methane is a much more potent greenhouse gas but it doesn't "last much longer in the atmosphere". Methane persists for about a decade vs. hundreds of years for CO2. See US EPA: https://www.epa.gov/climatelea... [epa.gov]
    • Sure, but many of the problems are happening in the short term. Everybody is promising to get to net-zero by 2050 but we need something for right now, too.

      Sure, but do you know what happens to most atmospheric methane?

      Wait for it....

      It is converted to CO2.

      Methane emissions are like the atmosphere getting kicked for a few decades, followed up by centuries of getting punched.

        Haha, I love it--an analogy that appeals to my violence and my stupidity.

  • The way this works is that it disrupts the components in the cattle's microbiome that produce methane. This may put evolutionary pressure on those microbes and the effect might not last.

    Scaling this up to a solution that can be fed to a significant fraction of the cows on the planet is an enormous undertaking. I've seen what algae farms look like, and they're large relative to the volume of freeze dried product you put out. Then there is environmental impact of freeze drying and shipping.

      Is that how it works? I haven't read the paper, not even when it was originally announced several years ago. If instead of eliminating methane production it opens up a pathway for some other bacteria to metabolize the methane on the spot, it won't disrupt the microbiome in cattle. I don't know which method of elimination is actually happening.

    I wonder if this will get any traction in the news media as an "alternative to eating less meat" or if the same drumbeat of "meat is immoral" will prevail.

    There is great skepticism in agriculture around the idea that cows are a huge impact to global warming, and a lot of it has to do with the messengers. Farmers are seeing the same people who have been anti agriculture (which sounds dumb, but believe me a nonzero portion of the population thinks we could all feed ourselves with backyard gardens) now just swap the attack line of the day out for "cows are a huge part of global warming!" They look back at the previous arguments against cattle farming, such as "we could feed the world if we didn't have cows" (starving people hasn't been a problem of supply for a long time) or "American beef eating is destroying the Amazon" (which ignores a very complex geopolitical situation where many nations, like china, want a more neutral producer of grains and are willing to fund Brazil to be that producer).

    The anti-meat lobby in particular should be understood as similar to anti-abortion groups: they fundamentally believe meat eating is immoral, and want to see it reduced to the smallest extent possible if not outright ended. That's not to say meat isn't over-consumed or that if Asia got the same taste for meat the west has it wouldn't be a huge environmental strain... but the current anti-meat push seems more like these legacy groups trying to capitalize on a popular issue to push their agenda rather than actual concern for global warming.

    All that said, if I'm wrong and everyone is genuine in their global warming concern this should be fantastic news. As long as the stuff isn't $1000 a gram it should be trivial for most cattle farmers to incorporate it. Feedlots are already using lots of mineral supplements mixed into feed daily, this is as simple as throwing one more five gallon bucket into the machine. On pasture many farmers also give mineral supplements, this could probably be worked in there too. In fact, that should make grazed cows pretty hefty carbon sinks.... ruminants have been shown to sequester large amounts of carbon in properly rotated pasture, as I understand it by promoting root growth and extending the healthy microbiome deeper into the soil with the extra air and moisture those roots bring. The question was always whether that outweighed the methane output, and the recent research has been somewhere between slightly more sequestration than methane impact to moderately less sequestration than methane impact. But if they don't make any methane then they're doing nothing but locking CO2 away. At least in existing natural grassland that is nothing but win from a CO2 perspective. In someplace like the Amazon not so much... really if you want environmental justice advocate tariffs on Brazil and other ag producers that are doing the ag equivalent of strip mining. American/Canadian and European farming is much, much more environmentally responsible.

      I don't give two figs about livestock but I do think society should move away from using real meat. The simple fact is that real meat is quite expensive and deeply subsidized. However, plant based replacements are far cheaper, can actually be more healthy, and lasts longer. Add on top of that the reduced land use, eliminating livestock health issues while enabling the possibility of total automation and you got a real winner. Removing the impact on the ecosystem is just icing on the cake.

      Meat is obsolet
