i am more than willing to engage on any positive claim you want to make (i probably agree with a lot of them). what i’m not willing to do is tolerate personal attacks and dogpiling.
seems like an appeal to authority, but i encourage you and anyone interested to look into how LCAs were abused, and how much cottonseed is weighed in the water use and land use of dairy milk, despite cotton being grown for textiles.
your BBC link actually just relies on poore-nemecek 2018, which abuses LCAs and myopically focuses on distilling other studies into discrete metrics without understanding the system holistically. in short, your claim about the environment may be true, but the source that you use to support it is incapable of providing that support.
The soy that's fed to pigs is almost entirely the byproduct of pressing soy for soybean oil. about 85% of the soybean crop is pressed for oil. if we didn't feed the byproduct to livestock, it would just be industrial waste.
your link doesn't seem to align with anything i've said. are you sure you used the right link?
