Writer and researcher on spiritual subjects, David Barreto, has studied astrophysics through the Australian National University, and Religious Literacy through Harvard University. His interest in animal spirituality began in his early teens when he discovered veganism, which resonated with him on a soulful level. He devoted much of his time to studying occultism, nutrition, and animal behaviour, which eventually led him to a professional focus. Today, his work encompasses a variety of ideals that support the animal cause, including animal rescuing, writing books, and delivering lectures.
