Well, it’s not as if they kill the calves to just get their stomach. As long as people eat meat I am all for using every possible piece of it. So the calve gets killed for its meat but if the organs and bones get used too that’s much better than throwing them away in my books.
We live in a world where almost every food we eat has in its production killed hundreds of animals. Crops, fruits and vegetables are high in pesticides and massive mono cultivation kills millions of small animals (and I am not talking insects here). And corn, soy and life stock are often a reason for cutting down rain forest. We dry out land, compact ground, contaminate our water with fertiliser and fly avocados, bananas, quinoa, rice and cocoa around the world just because we want it.
I am not shaming vegetarians or vegans. Treating animals with respect is a huge concern for me and I totally understand why someone would refrain from meat or all animal products even though it’s not for me. The meat industry plays also a big factor in environmental questions. I am rather concerned that we as humans always find a way of fucking things up. Instead of cutting back we often overdo it. Because a farmer in a third world country that butchers 4 cows (and use every single piece of it) a year is much less of a problem than a first world vegan that eats tons of superfoods that had to be transported around the world.
And vegan wine is a myth because almost every bottle contains the reminiscence of several dead insects. Same for juice. There no way to prevent it.
