"Why are you afraid of CO2?" Be afraid. Be very afraid. CO2 is deadly. Do you know how we killed the rats for the students in the biology lab, for fresh dissection? We used carbon dioxide. Deadly poisonous carbon dioxide. Kills them twice as fast as drowning. Drives the oxygen right out of their blood. Hemoglobin has stronger affinity for carbon dioxide than it does for oxygen. You put those poor rats in a big plastic bag. Plenty of oxygen, but they're getting pretty scared. Then you insert the tube and pump in the carbon dioxide. It knocks them out almost immediately. Drives the oxygen off the hemoglobin, so the rats exhale what little oxygen they had left, losing more with each breath. It doesn't matter that there is still at least 15% O2 in that bag with the rats. Kills them at least twice as fast as drowning them. Deadly poison CO2. "Life-giving gas", my ass! We should ALL be very afraid. Because by increasing the atmospheric concentration by 20%, from 350 to 420 ppm CO2, we have reset the Earth's thermostat. Weight is never added it merely shifts[/quote] My point about the risk is when it shifts from the land to the air.[/quote] No human life exists on Earth without greenhouse gasses in the air[/quote] Some say the ideal % of CO2 in the atmosphere is 0.02% and now estimates are 0.04%. I have no idea what the maximum sustainable ratio is. I just point out the risk if it goes beyond the maximum, whatever that maximum may be.[/quote] LOL, Al Bore gave up that argument over two decades ago.

Belching it out of their mouths, in case the "fart" thing is still an issue. The rumen is just too close to the mouth and too far from the butt for it to work. Those who believe there IS "such a thing" as methanogenesis - and that already excludes the authors of most posts at this website - might have some concerns about how that methane behaves when it gets into the atmosphere. Methane is a much more powerful greenhouse gas than carbon dioxide. Those who believe there IS "such a thing" as greenhouse gas - and most active posters at this are not among them - might have some concerns about how cow gas could be a factor contributing to all this extreme weather that has become the new "normal" for our climate. And those of us who just LOVE biogeochemistry want to share relevant information for scientifically literate folks who might be interested. Forty new viewers a day, even when they had to take an extra step just to even FIND the thread, gives me confidence that such folks are out there. |

"There is no such thing as 'methanogenesis'.", says the Chemistry Clown whose 23,000 posts of parrot poop comprise more than one in five of all posts ever posted on this website. According to Merriam-Webster, methanogenesis is the production of methane, especially by methanogens, occurring in anaerobic environments. Like all the chemistry and biology textbooks, the Merriam-Webster dictionary seems to agree that there really IS such a thing as "methanogenesis". COW GAS forms in the rumen, not the "true" stomach. One reason cows BURP methane rather than farting it (tee hee) is that the methane is generated before the cow's meal even gets into into its "true" stomach. Cows are ruminants, a line of animals that have a rumen "stomach" where their meal is fermented before it enters the "true" stomach where it is digested. Our stomachs are pretty much like the cow's true stomach, generating very low pH (2-4) with hydrochloric acid to digest our food. But ruminants evolved a big stomach-like pouch (rumen) where they ferment their meal before beginning to digest it. The pH in the rumen is MUCH closer to neutral than the cow's acidic "true" stomach. Rumen pH ranges about 5.5-6.9. Cows don't absorb any nutrients from their rumens. They just use it as a fermentation chamber where a microbial feeding frenzy occurs under very low oxygen conditions. Some of those microorganisms generate hydrogen gas in the cow's rumen. Methanogenic archaebacteria in the rumen then combine that hydrogen with carbon dioxide to make methane. 4H2 + CO2 = CH4 + 2H2O plus small exothermic energy yield All this happens before the fermenting cud ever gets into the cow's "true" stomach. The methane produced by bacteria in the cow's rumen only has one way to get out - BELCH! So, when the cud is nicely fermented it contains a lot of bacterial biomass that transformed the cow's cellulose-rich feed into protein-rich, fat-rich microorganisms. It is then passed into the true stomach where actual digestion and nutrient absorption occurs under strongly acidic conditions. By the time it gets into the cow's intestines, the methanogenic bacteria are digested and absorbed and unable to make any more cow gas. Another fun fact. Like every other vertebrate, cows cannot produce an enzyme that could digest cellulose. However, there is a single-celled protozoan in the cow's rumen, far larger and more complex than the multiple species of bacteria also present. That protozoan harbors a bacteria that makes the elusive enzyme to digest cellulose. In a three-way symbiosis, the cow hosts the protozoan which hosts the bacteria that makes the cellulase enzyme. The fermented cud is loaded with microbial biomass far more nutritious than the original fodder the cow took in. I'm not saying that ruminants are incapable of flatulence. But "cow gas" virtually ALL comes out of the FRONT end of the cow. Fart jokes can be funny. But dismissing and belittling the climate change contribution of cow gas by mocking it as "farts" displays more than just veterinary ignorance. Here it is: August 25, 2024 The Washington Post Scientists may have found a radical solution for making your hamburger less bad for the planet. by Shannon Osaka and Emily Wright ---------------------------------------------------------- COW GAS! The dreaded methane emissions from bovine digestion. Gram per gram, methane has 20-30 times as much global warming potential as carbon dioxide. Why do cows emit methane? Well, cow guts create extreme low oxygen conditions that allow microbiological fermentation reactions to occur. Some of those little critters produce hydrogen gas. Okay, so if cows are emitting hydrogen gas, that's not so bad, right? But that's where some different little critters some in. Methanogenic bacteria. Descendants of one of Earth's very oldest line of bacteria. They combine hydrogen gas with carbon dioxide to produce methane. So, a lot of work has already been done looking at how to optimize the composition of the feed to minimize methane emissions from cows. I take pride in having pioneered research into polyphenols for such applications. But the NEWEST twist may be to just tip the scales of the microbiological ecology of what happens inside the cow guts. One approach is to introduce a different guy who is better adapted to catch the hydrogen gas, intercepting it before the methanogens get a shot at it. Another approach is to introduce more of the guys who ferment WITHOUT generating hydrogen gas in the process. Either way, germ warfare could help us cut back on cow gas emissions. |
