Well quite, all of this has been covered many many times on the FF. A quick google doesn't equip you to battle these people properly as they are well-versed in presenting dodgy soundbites as well-researched "facts".They will be quick to tag you with the methane bit, so you need to take a bit of time on Google, about a half hour and get it straiqht. Methane is a gas similar to CO2 but not exactly the same. It will degrade over a 10 year span. CO2 emitted by burning fossil fuels is a different molecular structure and does not degrade.
Another they will be quick to tag you with is soybeans. Another half hour on Google checking soybean councils and production w3ill provide you with the following. Yes all soybean meal goes to feed animals. The kicker, as you will, is that soybean meal is what is left after the soy beans are processed to remove the soy oil. The oil is used for human consumption so the animals are doing the companies a favour.
If you are having trouble finding some of this, I do have some of them saved and can send them if you wish.
Google is a huge part of the problem, it directs you to websites that by their very nature barely skim over the top of the problem without actually revealing sound science. Methane from ruminants is a prime example of precisely this. Just have a look at Our World in Data's website: the go-to website for "facts" and charts. Every single piece of data on there used GWP100 as a measurement for methane. We now know this to be fundamentally wrong as a methodology for methane and so ALL of that website is wrong. GWP* is the newer better methodology and is fit for purpose now and we need to bring pressure to bear at every opportunity. The vegan propaganda machine is hoping to keep this quiet as it leaves their arguments in tatters. Delilah is doing good work on here showing us all what we're up against. But we have ammunition now, research it properly so you can challenge their rubbish and eviscerate it properly.
