The real world we live in

[DeliciousFood]

In this world as it is all non-photosynthetic organisms eat each other (definitely an aspect of vore there) and almost all organisms will be eaten and become excrement. In addition, the human race farms billions of animals each year that are slaughtered, sold, and eaten by the general public without second thought before they become billions of stinking turds. There seem to be few stories that focus on these real aspects of the world.
WHY?

Not too sure. People get squeamish about real life stuff. I'm a vegetarian, but watching "Sausage Party" (with sentient food) really doesn't let me off the hook. As a personal fan of the post-vore stuff, I always got a funny feeling as a kid when my young friends would eat bugs. Yeah, that thought occurred to me back then, realizing that worm was soon to be poop.

Because eating isn't necessarily vore, and most vore requires at least one sentient participant to be well-recieved.
