So re-introducing thousands of Bison to the prairies is a good thing, and millions of Wildebeest in the Serengeti is fantastic but grazing cattle is destroying the planet?
I just don't get it!
The whole job is hypocritical all thru . Its same with the power generation its green when you turn the key but we will forget all about what went before to get to that point !

Less than 20 years. Somewhere between 12 - 14 years calculated by most accurate methods. And let's not forget methanophages. They are the heroes when it comes to Earth's regulation of methane from living things within its cycle. Our livestock are part of nature.

Are you saying that regardless of how many runinants are in the world, the methane level from them would remain at a constant level?

It comes from the rumen bacteria. Plants take in carbon dioxide, but the rumen bugs digest grass and make methane.
Methane only exists for 20 years or so before it breaks down to Carbon Dioxide. But during that time, it has a warming effect 25 or 86 times higher than CO2 (depending on how its calculated.)
So that is part of the methane carbon cycle. If methane emmitions from livestock are stable, is there then no net contribution? I don't no the data on this though. So should this be consideration.
I previously missed the bit where the the carbon is also stored in the root mass later to become soil Organic matter.

Question:
When we talk about carbon footprints, is the amount of c02 absorbed by the plant taken into account?

My understanding is that Earth has its own means of keeping levels constant. It's part of the natural web of life for living things to exist within that beneficial loop, and phages are part of the web which seeks to maintain stability.
Beyond that, I would need high level mathematics to describe what goes on, which is something I don't have.

Spot on!

Answer to your question: Much depends on just how much of an anti-meat activist/vegan worldview promoter is the person who draws up the interpretation of the statistics.

Surely the atmosphere has been warming up since the start of the Industrial Revolution.
I just Googled “when did the Industrial Revolution start”,one of the answers is “The Industrial Revolution started in the 18th century when agricultural societies became more industrialised and urban”.
So the farming bashers need to realise that it was when society moved to industry from farming that the atmosphere really started to get slightly warmer. So how can farming suddenly have become one of the SUPPOSEDLY worst polluting industries on the planet.???? :scratchhead: :rolleyes:
It has not it’s just bloody lies ontop of lies and more lies

Id guess its because farming hasn't stayed at pre-industrial levels.

Someone once suggested methane has a fingerprint, depending on its source.
I'd like to know if this is indeed true, and if it the atmospheric methane had been studied to find its origins.

Correct. I guess the question we ae being posed is, is current levels acceptable?

Current levels from our livestock are probably absolutely fine. Future levels from our livestock will probably be absolutely fine, too. It's methane and CO² from fossil sources which are the problem. We clever descendants of apes need to put the brakes on extractions and uses of fossil carbon that release GHGs which the natural carbon cycle cannot deal with.

It's true that different sources of methane have signatures. There are monitoring stations in orbit which are deciphering those signatures, and locating their sources. I'm sure that there was something on one of the BBC platforms about it, thinking about it.

Interesting. I'll add that to my list of research along with finding @Cowabunga s mythical source.

Hope you don't have to stumble through too many herds of unicorns whilst on your quest 😁

If you manage to find the BBC headlines from 2015 that made a very big deal of the public retraction of the Anderson (and others) study, thus releasing farmed ruminants from any accusations about climate change, please do post the link. I've searched, but haven't found them yet. I've strong memories of it being 24 hour headlines back then.

This is supposed to show atmospheric pollution and the pollutant selected is Methane (red bad- violet better - white none)

I didn't realise there were so many cows in Central London!

Or perhaps she is encouraging us to make sure we have our house in order so no one can critisise us as we go banging on about the aviation industry.
Yea sure according to her by improved genetic breeding leading to a few more cows that don't burp, for christ sake get real the roads are jam packed, houses being built just about everywhere, pollution & sh!t from towns & cities all over the country & you seriously expect us to believe that we are the problem!
