Eating eggs -> financially supporting a system where male chicks get either immediately killed after birth or more rarely are later killed for their meat. Also it is supporting a system where chickens are bred to produce as many eggs as fast as possible, which means a life of torture to them

Drinking milk -> financially supporting a system where cows are continuously impregnated against their will and where their offspring is immediately taken from them and killed for their meat (I think this is done yearly). Also it is supporting a system where cows are bred to produce as much milk as fast as possible, which means a life of torture to them

There are certainly many more atrocities happening, but I’m trying not to think too often of that stuff
