about 10% of the energy and nutrients animals consume get passed down into humans (ie for 10kg of feed we get 1kg of meat - i’m actually surprised it’s even this much!)
that means if we get those nutrients from plants directly for every 10kg of plant we get - perhaps not 10kg since there’s still waste, but you don’t waste 90% of the plant to consume
even poore-nemecek doesn’t say this. do you have a source that does?
well that part is just logical
