The idea of kangatarianism began in early 2009 when a small group of friends in Sydney learnt about the benefits of kangaroo meat and decided to pass their knowledge on. Notable in spreading the word was kangaroo-meat advocate Peter Ampt, a lecturer in natural resource management at Sydney University. The word kangatarian started out as a joke, but then began to catch on as more people became interested in the concept. Perhaps even more surprisingly, more than one form of kangatarianism has now been proposed, such as pesco-kangatarianism for those who augment their vegetarian diet with kangaroo and seafood; pollo-kangatarianism for those who eat kangaroo and poultry; and pollo-pesco-kangatarianism for those who consume all three.
