Baby moos

The cows in the field opposite the shop were very inquisitive today.
A few weeks ago, one of them was mooing inconsolably - turns out they had taken her calf away, probably to be slaughtered.
It was heartbreaking how she kept calling and looking for him. Which got me thinking that that's basically what happens at most dairy farms - the cow has a calf which gets taken away so we can have her milk, and once she dries up the same happens again. I can see how that would make people go vegan.
Food ethics. Interesting topic.
