“If you wish to make an apple pie from scratch, you must first invent the universe.”

— Carl Sagan

e.g. to get the cow to make milk you have to get it pregnant and thus you get an unwanted calf.

Thank you. I was a little bit disappointed that these more sinister parts were occluded but I guess that is to be expected after all, the dairy industry spends insane amounts of money to keep us gaslighted. Just ask somebody if cows give milk without being pregnant...

Let's also not forget that the article basically skips what rennet actually is just naming it an enzyme.
