If someone caused us to reproduce for the purpose of using our offspring as unpaid labor, then attempted to justify this by claiming that they intentionally bred our children specifically for slavery, would we consider it justified? No, we wouldn’t. In fact, their answer would likely (and should) cause us to feel outrage.
Even if a person believes that humans are more important than animals, the fact that animals’ lives are important to them is sufficient reason to avoid unnecessarily harming them.
