do human farts contribute to global warming?

Answer 1

Not really, but studies have shown that gas passed by cows contribute to the problem... just another reason to avoid beef...

and it's methane gas, not hydrogen......

Answer 2

Humans fart 12-25 times per day on average, releasing a grand total of 0.5-1.5 litres per day. The 3 main gasses present in a fart are nitrogen, carbon dioxide and hydrogen. The odourous gasses make up a small-but potent- amount of the total volume of gas released.

So where do these gasses come from?
90% of the gas in flatulance comes from air that has been ingested from the mouth or nose.

The remaining 10% is produced by intertestinal floura, the bacterial communities that exist within the intestines. These microorganisms metabolise proteins, lipids and carbohydrates from the food passing through the intestine. The products from this metabolism are the gasses hydrogen, methane and carbon dioxide.

Proteins are large macromolecules made up of long chains of amino acids. The proteins are broken down into amino acids, and these are further metabolised by the microrganisms producing reduced sulphur compounds like hydrogen sulphide(smells like rotten egg).

In anerobic conditions (anerobic=without oxygen, a common situation in the intestine) fatty acids are not fully metabolised into carbon dioxide and water (respiration). Instead the microraginsms harvest as much energy from the fatty acids, and this incomplete breakdown produces a shorter fatty acids- butyric acid(smells like rancid butter smell).

These odourous compounds are expelled from the body during flatulance, and they diffuse into the nose of unfortunate individuals. Olfactory receptors bind these molecules, and send a signal to your brain which you interperet as an unpleasnt smell.

I can not be bothered to find the exact concentration of carbon dioxide or methane in a fart, but seeming as these gasses are produced, farting does contribute to global warming.

Answer 3

I suspect that by the time any of the gasses in question reach a point in the atmosphere to which they are able to contribute, twice as much will have been used, ot dissapeted in some other way, so NO to that then.

By the way to the guy still living in the COLD WAR, get over it buddy communism is not out to get you personally, and if your happy for your great grand children to grow up in a poluted world carry on driving you gas guzzler and never recycle a damned thing, but the way I see it is so what if it is a hoax, it cant do any harm using less fossil fuels and recycling more, economically it makes sense anyway, regardless of the benefits to the environment!

Answer 4

What global warming? Year after year, NASA measures the temperature of the planet, and it hasn't changedf as much as 0.1 de degrees.

What we have is the people we used to call Communists, still trying to trick us into one world government, and you can be sure the US won't have much to say about that government! When they realized they could not get the 1-world gov't for economic reasons, they shifted gears, and now we have one bogus environmental emergency after the other, trying to panic dummies into accepting a 1-world gov't for environmental reasons.

The first one was the freon - ozone layer hoax. Freon is a very heavy molecue, which is totally incapable of floating up 15 miles to destroy the ozone. ROCKS DON'T FLY!!

Further, this all happened right after the US first got the capability to measure the ozone layer, and they had not realized the dark place at the poles would be short on ozone -- where the sun doesn't shine, ozone doesn't matter anyway,

The wacko journalists immediately went on a campaign, we gotta' get rid of R-12, and the scientists tried to tell them we had no reference to know what was normal.

Yet, all you guys bought into it hook line and sinker.

Ditto for global warming. If you had any education, you would know there is a 1700 year temperature cycle, and we are not in the hot part now.

IF you had any education, you would know in the 1890's, there was a fast melt off of the polar glaciers, and shortly after the turn of the Century the ice came back.

To some extent, I don't care what you guys do. I am 64, and in around 20 years, I expect to die of old age. But, some of you are still really young, and you will suffer if you don't wake up and start THINKING before you panic as you have in the case of ozone and warming.

It is amazing that it is easy to get you to accept the belief that G.Bush is personally responsible for 9/11, but can't see through such easily debunked things as ozone and warming hoaxes.

Answer 5

There are much more important things that contribute to global warming. I can't believe this is a question. Global warming is an important issue.

Answer 6

Not to a significant extent. The component of flatulence that contributes to global warming is methane, and there is a lot more methane in the flatulence of livestock than in that of humans. 20% of the world's methane emissions come from livestock. Furthermore, 90% of the methane released by livestock is released through burping, not flatulence. The contribution from human flatulence is insignificant.

Answer 7

Yes, they do. Much is made about how cow farts are adding methane to the atmosphere, but everyone is silent about the human contribution. Granted, cows produce much more.

Answer 8

Yes they do. A fart is mostly methane, a gas which has a strong effect on the atmosphere. Cows are a relly big contributor of methane!

Answer 9

no, but robots do.

we need to get them to vent exhaust simultaneously, in order to move the planet further from the sun, but still remain in orbit.

it'll make the year a week longer, so we can make that robot party week.

Answer 10

If they do my step dad is in real big trouble!!! I have cows in the field opposite me they eat chocolate chip cookies!
