But this is complicated by the fact that we don't need to have _any_ animals for food at all, so there are still ethical problems with even raising animals lovingly in wide open pastures for years before killing them. For example, we still see it as wrong to kill a dog if we get bored with it after loving it for years and giving it an incredible life. The developed world has entered a phase of civilization where we can get everything we need to live without farming animals for meat, so we have a moral obligation (in my opinion) to do so, as it means we don't have to kill _any_ pigs that don't want to die
