The moral justification comes from the understanding that the brain is an organ which integrates information to form this profound feeling of presence that you and I share. There is zero evidence to suggest that we don't share this feeling with animals. This is a scientific argument. I'm a professional neuroscientist working in brain simulation, and even the complexity of a ringworm is out of the grasp of the field. The complexity of the brain is unrivaled anywhere else in nature, and it has this wonderful emergent property that I feel like something. Animals feel like something. It feels like something to be a cow, a chicken, and a pig. They understand and relate to the world. That is why it is wrong to kill them unless you have to.
