A cow that's fed on gras and farts emits nothing that that gras didn't pick up and contributes virtually nothing to climate change in the long term.
Otherwise, I wonder if non fertilizer supported grass could support sufficient cows to satiate demand (which has not even peaked yet).
but focusing on that is shifting blame in an innefectual way of course. Pointing at cow farts puts the pressure on the individual and seeks to dampen effects in the short term. Pump up less or no fossil fuels with actual long term thinking and those fertilisers will automatically become more expensive. At that point tho our oversized animal herd becomes harder to support and beef becomes automatically a lot more expensive whilst at the same time the manure becomes more important.
Also, from that Wikipedia article:
There is accumulating research and data showing that oil and gas industry methane emissions – or from fossil fuel extraction, distribution and use – are much larger than thought.[35][36][37][38][39]
Still, my “astronomically dwarfs” looks to be overstating it by a wide margin.
Yeah, but they also provide 80% of the world's calories to animals' 20%
Apparently mainly rice growing. I knew paddy fields were bad, but I didn't know they were that bad. Per calorie I am sure it is more like a tenth that of ruminants, perhaps less, but still worth replacing with other carbohydrates.
Complete rice also carry lisine (although less than beans) which is a really hard amino acid to get on a vegetarian diet.
