Plant-based mince is now 29% cheaper than beef, lamb, and pork mince at Tesco, according to a price comparison conducted by nonprofit think tank GFI Europe
Almost all global meat production happens in factory farms. Especially in developed countries with the highest meat consumption. I will look at the US for an example:
Currently, ‘grass-finished’ beef accounts for less than 1% of the current US supply
We estimate that 99% of US farmed animals are living in factory farms at present. By species, we estimate that 70.4% of cows, 98.3% of pigs, 99.8% of turkeys, 98.2% of chickens raised for eggs, and over 99.9% of chickens raised for meat are living in factory farms. Based on the confinement and living conditions of farmed fish, we estimate that virtually all US fish farms are suitably described as factory farms, though there is limited data on fish farm conditions and no standardized definition.[1] Land animal figures use data from the USDA Census of Agriculture[2] and EPA definitions of Concentrated Animal Feeding Operations.[3]
Even if those other methods could magically do much better, which I significantly doubt given the history of those kinds of methods over promising and under delivering, it does relatively little good to look at any other method because they do not come close to scaling to the level of consumption we’re seeing here. A pasture only system could at most come to a small fraction of production. Using 100% of the land, which would create huge deforestation pressures
We model a nationwide transition [in the US] from grain- to grass-finishing systems using demographics of present-day beef cattle. In order to produce the same quantity of beef as the present-day system, we find that a nationwide shift to exclusively grass-fed beef would require increasing the national cattle herd from 77 to 100 million cattle, an increase of 30%. We also find that the current pastureland grass resource can support only 27% of the current beef supply (27 million cattle), an amount 30% smaller than prior estimates
[…]
If beef consumption is not reduced and is instead satisfied by greater imports of grass-fed beef, a switch to purely grass-fed systems would likely result in higher environmental costs, including higher overall
methane emissions. Thus, only reductions in beef consumption can guarantee reductions in the environmental impact of US food systems.
EDIT: It’s also worth noting that a lot of people that start on things like beyond and impossible end up eventually switching to much more whole plant-based foods in the end anyways. It allow a lot more easy room to bridge to whole foods than starting with just 100% whole food is for a lot of people
I will look at the US for an example
By species, we estimate that 70.4% of cows
Cool. As the authors of the study I linked wrote, with sources, global stat is <13%.
Example: dairy, 1 liter of milk requires - depending on the method and location -between 19L of freshwater (section 5.2) to almost 3000L, median 196. In USA it starts at ~700L.
99.8% of turkeys, 98.2% of chickens raised for eggs, and over 99.9% of chickens raised for meat are
Interestingly average poultry requires less land than average pulses. And there’s this gem from section 5.2 (again, the linked document has further sources) further explaining why LCA or applying US averages globally is wrong.
As another example, that the lowest 10 percentile footprint dairy farms have lower greenhouse gas equivalent emissions than the 90th percentile soy, nut, and oat farm

Same study, point 4.1.
which I significantly doubt given the history of those kinds of methods over promising and under delivering
5.1 and 5.3 why Beyond Meat and similar are over promising and under delivering, with already established examples that show that the substitutes did not decrease meat/dairy consumptions but added to the total consumption.

I think this is my last post in the thread (and I guess yours too, we seem to exhaust the topic between us).
To sum it up:
we agree on whole plant based diet being the goal
we disagree on the interim diet and how to encourage and enable the transition from current meat-based diets

the hayek paper uncritically cites poore-nemecek 2018. I don’t believe they are practicing good science here, either
what a thread to hold on to.
leave me alone
I imagine that’s what the animals might say.
