could easily swap "fossil fuels" for animal products here.
Except the climate change contribution of all agriculture combined is only a fraction of that caused by fossil fuels.
A lot of agriculture is driven by fossil fuels though. Or, more specifically, fossil fuels in energy and transportation, as well as in fertilizer production.
Probably more so for fruit and vegetables than meat though, crops require diesel farm equipment in virtually every aspect of their production, whereas animals are self propelled
Well except that we first need to use all the sane diesel farm equipment to grow soy and corn crops that we can then feed to those self propelled animals.
In most of the westernised supply chain livestock animals don't get to propel themselves very far anyway. Where once farmers would drive cattle to market on hoof, now they litteraly drive them in a truck.
Depends where you live, the cattle and sheep where I live just wander around in the paddocks and eat grass for the most part.
Besides, cattle trucks are public transport for cows anyway, very efficient.
That is not how Western cattle farming works. As someone in the industry I can confidently say that no cow sold to a processor get a majority of their calories through grazed uncultivated grassland.
That is a feasible strategy for subsistence farming, but not in our for-profit farming model.
That's a BIG part of the reason agriculture scores so high on this chart, yeah
I'm not saying that animal husbandry isn't contributing a lot to climate change, but compared to fossil fuels, it's absolutely miniscule.
I would love a source on this
A quick search failed to produce an article or study directly comparing the two, so I did each separately.
The livestock sector requires a significant amount of natural resources and is responsible for about 14.5% of total anthropogenic greenhouse gas emissions (7.1 Gigatonnes of carbon dioxide equivalents for the year
Livestock pretty much entirely contribute to climate change inherently via methane and incidentally via use of fossil fuel for transport and specialized machinery. If all of the latter went fully electric, that 14.5% could probably go down to 10% if not 5%..
To call 5 to 14.5% the equivalent of 73% is absolute lunacy that smacks of ideological bias, especially since you don't mention plant farming, which contributes a lot as well.
Animal agriculture produces 65% of the world's nitrous oxide emissions which has a global warming impact 296 times greater than carbon dioxide. Raising livestock for human consumption generates nearly 15% of total global greenhouse gas emissions, which is greater than all the transportation emissions combined.
Very much cherry picking data points here: nitrous oxide has a higher impact by volume, but the output is infinitesimal compared to CO² and other harmful substances involved in the extraction, processing and combustion of fossil to the point that it's still a TINY problem in comparison.
As for this part
15% of total global greenhouse gas emissions, which is greater than all the transportation emissions combined
That's just a flat out lie.

The problem I see here is that it measures greenhouse gas emissions, but not "net greenhouse gas emissions", which is much more important.
For example, "crop burning" contributes to the CO2 emissions short-term, but not long-term. Still they list it as "3.5%" of emissions.

hmm, I didn't have any issue finding studies that compare the two; here's one:
