How can we incorporate animal welfare education into the school curriculum?

Throughout the history of not just humanity but the entire planet there’s has always been a food chain. A lion does not concern itself when eating its prey because it does so to survive. Our bodies have evolved to eat animals and function of their nutrients and minerals. So i believe animals or more specifically livestock shouldn’t have the same rank in society as people. Although over hunting as poaching is a problem and has to be addressed as we can’t have species going extinct as that damages environments.
