(That's why grass fed cows are ideal, obviously. Milk from grass fed cows is incredibly nutrient dense. I'd call it essential.)

grass-fed milk production is an even greater strain on the environment, completely unsustainable, and also still stealing the milk from someone else’s mother. it literally is not even ours to take in the first place. there’s no right way to do the wrong thing.

i will agree with you on one thing, though. it IS essential. FOR CALVES. you are definitely beyond the age of weaning and clearly not a cow if you were able to type this. leave the breast milk for the actual babies, please.
