Cowed

January 28, 2008 4:03 PM

Cows_080125_main If you worry about a warming climate you can look at your Hummer and feel anxious, or you can take comfort that some solutions don't demand that we give up such comforts.

Quoth the Times of London: "A team of Japanese boffins may have accidentally struck gold in the fight against global warming: they believe they have devised a way to neutralise the perilous belches of 1.5 billion cows."

This is not entirely a surprise; methane from ruminating cows has been cited for years as a source of greenhouse gases, and about a year ago the U.N.'s Food and Agriculture Organization suggested barnyard methane may be a larger source than transportation.  (More HERE.)

Leo Lewis of the Times continues: "According to the team from Obihiro University of Agriculture, a few simple food additives, costing about 50p each day (about $1 U.S.) per cow, could remove virtually all methane from a herd’s daily output of greenhouse gas-enriched belches."

The Times has a nice, staid picture of a cow to illustrate its piece.  Gizmodo picked it up; their image, borrowed from Treehugger.com, is more, er, vivid.

Hat tip to Brian Hartman of our Washington bureau for this.

I have read about this before and in some detail. Methane is a much more serious greenhouse gas than CO2 and reducing methane production would have a much larger effect on atmospheric warming. It's no surprise that the Japanese would figure out how, they have the best beef in the world and are not about to switch to chicken. :}

When cows and other animals exhale CO2 it doesn't have the same effect on global warming that fossil fuels do because the carbon came from the air in the first place. On the other hand, when cows convert the carbon to methane form, they are turning it into a more potent greenhouse gas, molecule for molecule. I'm skeptical that they can make anything about cows more pleasant, but they are welcome to try!

Wow how we have steeped so low to outright blame farmers cow's for a large portion of "global warming" (20 years ago it was "global cooling") now they want farmers to pay extra to fight "global warming". its like saying people without hair are a disgrace to society and they should pay for spray on hair to fix it. want to help the environment, lets ban smoking, which has a much more harmful affect what co2 or methane has produced.

$1/day/cow does seem like a lot of money, now that you mention it, so I'm not sure this would be the best place to spend our carbon-reduction investments (if anyone were actually taking this seriously in the first place). It seems like fewer cows might be a more useful approach. But pretending that climate change isn't happening is not very helpful either, Adam.

this is awesome but it sure costs a lot of money. How long are they going to keep this? Oh buy the way go japan

Posted by: Jerry | Jan 28, 2008 7:13:36 PM

It's definitely too expensive. 1.5 billion cows works out to over half a trillion dollars a year. They need to get it down to 10 cents a day per cow. Or people need to cut back on the beef and eat non-belching chickens and fish.

Adam: It's just simple biology. Cows and pigs produce methane. Methane is a greenhouse gas. It's not the farmers' fault that people like beef and pork - they're just raising the critters. And I seriously doubt that the farmers would bear the costs. It would be the meat-eating public that would have to pony up the extra cash.

Jock, you blame AMERICA for global warming as you ADMITTED. Well, I have news for you. The nation that actually emits the most Co2 is CHINA.

cturple
Have you ever checked the price of Kobi beef?

Posted by: Ed | Jan 28, 2008 10:51:36 PM

ivan234 - The fact that China is about to pass us in absolute emissions is hardly news. But most of the CO2 already up there is ours, and we continue to emit CO2 at more than 4 times the per capita rate of any other country. So we do bear significant responsibility. But I don't "blame" only America, of course; all countries contribute to global warming and need to reduce emissions. But the fact that other countries also emit CO2 is no reason for the U.S. to refuse to act responsibly, like the little boy who gets in trouble and his first defense is "Jimmy did it too!" Leadership means you do the right thing FIRST, not last.

Yeah I ask my brother what are you going to do with that Hummer sell it keep or let it set or trade it? As Americans wouldn't be wise to all drive Hybirds and stop emmision now what are we waiting for another Katrina and dome day and see if FEMA will put us up in a tent on day or a football stadium where is the leadership here??

Does anyone care yet to smell the coffee or wake up before we get caught in a twister or earth quake before we wake up running in fear when the next distaster hits.

Posted by: Gloria | Jan 29, 2008 1:09:09 AM

Great on Japan

Posted by: Gloria | Jan 29, 2008 1:17:06 AM

I better tell my brother he just keep his hummer, don't listen to the news all the time.

Posted by: Gloria | Jan 29, 2008 1:19:43 AM

I just check out the EPA site again it's been 5 years since I last checked out that site. Now I know why I was so sick living near a landfill and factory and behind a wetland area, after I moved three months later I thought I was going to die if I didn't move from that area. Methane is toxic and silent killer

Posted by: Gloria | Jan 29, 2008 1:32:46 AM

No one beleived me when I said I was sick and the doctors kept there mouth shut I notice when I brought this up. They said it was all in my head. Science and History have alway been my favorite subjects.

Posted by: Gloria | Jan 29, 2008 1:35:29 AM

Ed: I know Kobi beef costs more than I would pay for a car. ;-)

Posted by: cturple | Jan 29, 2008 7:00:18 AM

my previous comments helped when I mentioned do you all need to recall every car back on the lines.

Posted by: Gloria | Jan 29, 2008 7:16:11 AM

How did the Methane get beneath the water did someone dump it there?

Posted by: Gloria | Jan 29, 2008 7:44:47 AM

changing our emmisions fast on vehicles would have really hurt the economy as a recall.
