This is a very difficult subject and rather graphic and shocking, if you are not familiar with modern meat production.
Modern “factory farms” are in absolute violation of every biblical command for the treatment of animals. The provide improper food (not healthy food). They do not protect the creatures from harms but in fact create new harms. They do not allow a Sabbath rest or any rest since the creatures often live without sunlight or pure air.
Although meat is not evil; supporting the factory farm system is not right.
