So my diet is better than a vegan family of four? Glad I got that vasectomy.
What’s new to me in this data is that the increase in cropland for humans for a vegan diet is still less that what we currently feed to animals in spite of the enormous amount of pasture they also require.
except that the food that is fed to livestock is largely crop seconds or parts of crops that people can’t or won’t eat. so we need to find a whole other use for those parts of the plants or accept it as waste.
Or we can use it as compost, which we should be moving towards producing and using instead of manure as fertilizer for a lot of our agriculture. That way it doesn’t go to waste even if it does get ‘thrown out’.
I know a lot of people who grow feed on prime agricultural land. Like, can you eat alfalfa? Have you ever tried feed varieties of maize?
people definitely eat alfalfa sprouts. to be clear, i didn’t say no land is used explicitly for feed, but much of the land that is used for growing feed is actually growing some crop that will produce multiple products, with feed being only one of them.
Looks like we could change to just eating poultry and have roughly the same effect
Poultry is definitely the more climate friendly of the meats but it doesn’t come without problems
There’s still increased risks of pandemic with factory farmed chickens and most chickens are raised in inhumane conditions
this is exactly what i do: replace most of my beef consumption with pork, chicken, and kangaroo
i don’t cut out beef entirely because i think abstinence is a recipe for relapse (if i reeeeeally feel like steak or a beef burger i’ll do it but that happens maybe 3 times per year)
i do not miss beef
looking at the dairy part of this however i may need to do more research and move to other milks in my coffee!
I suppose this doesn’t take into account more humane animal farming? Like not keeping a million chickens and three long barns? Or pigs with a livable space?
The thing with pigs is: they eat a metric fuck-ton, so a lot of that land usage is to grow grain for feed.
That’s the vegans’ main point – we grow food to feed it to our food.
pigs are mostly fed crop seconds or other waste product. it’s just not true that we are growing food exclusively for pigs.
They still haven’t figured out a way to humanely slaughter animals let alone keep them in fulfilling environments that would be impossible to tell from their wild counterparts.
We can’t afford to let animals live full lives. Pigs are butchered at 6 months but can live decades naturally.
We haven’t even begun to approach the conversation of maybe possibly being able to in the maybe distant future being able to consider a humane way to keep animals and then also harvest meat from them when they pass.
this is based on poore-nemecek 2018, a paper so fraught with methodological faux pas as to be a warning to anyone trying to do a metastudy.
Following the trail of your comment: https://ourworldindata.org/land-use-diets does indeed cite https://www.science.org/doi/10.1126/science.aaq0216, but I’d love it if you could provide more details on your criticisms of methodology.
this paper is over half a decade old, and i’ve been whining about it pretty much that whole time, but i don’t recall the last time i actually dug into the methodology. to my recollection, they call it a metastudy and they compare LCAs from disparate studies, but LCAs themselves are not transferable between studies. that’s just one point.
if i recall correctly, they also used some california water study as the basis of their water use claims, but the water use included things like cottonseed, which is not grown for cattle feed, and using it in cattle feed is actually a conservation of resources. cotton is a notoriously light and water-demanding crop, so using the heavy byproduct to add to the water use of california dairies is, to me, dishonest.
i have no doubt that if i were to slice up this paper citation-by-citation, every one of them would have some misrepresented facts or methodology being repackaged as, i don’t say this lightly, vegan propaganda.
Dug up the paper in question for anyone curious: https://sci-hub.se/https://www.science.org/doi/10.1126/science.aaq0216. At a cursory glance, I’m not seeing any of the referenced concerns. But, y’know, down vote away I guess.
So what’s a better study or metastudy? The actual results, aside from poultry being weirdly low-resource, seem about right when you consider the way energy usually moves through food webs.
That’s “Life Cycle Assessment”, for anyone else that’s wondering.
Do you often feel attacked by vegans? What exactly is vegan propaganda? Everyone uses studies on both sides, that’s how unsettled science works. Are most of them wrong? Of course, because again its not settled.
Seems convenient to discount the other viewpoints studies as propaganda when the opposing side is funded just as precariously.
