'Placentophagia' is the act of mammals eating the placenta of their young after childbirth. As you might imagine, it is business-as-usual in nature but in the modern human world, the act is fraught with all kinds of thorny issues and rarely are they discussed openly. Here, one blogger takes on the issue from a religious viewpoint:
"But what about the argument that placentophagia goes against God’s will? That one, my friends, is a religious question and I am not a theologian. However, Anna Marie Zalesak has studied philosophy and Catholic theology and has written a great argument in support of placentophagia for Catholics."
