What is your thoughts about the replaceability argument ?

 

For me replaceability argument is something like compensating the welfare loss that is implied by the killing of animals that would lead to happy future. Thus, any being on this earth who experienced pain or suffer has a ver least or has the right not to be forced to experience pain or suffer be killed unnecessarily. And it is not necessary that we inflict pain or suffering or death o animals so that that we can have a healthy diet. Therefore, to inflict unnecessary pain or suffering or death in an animal so as to eat it is morally reprehensible.
