Top Definition
A term used to describe documentary footage of natural life or other phenonema which invariably grabs the viewer's attention and can be habit-forming, much like regular porn.
Person 1: Dylan is totally addicted to nature porn.

Person 2: I know, every time I go over there he makes me watch the scene from Planet Earth with the fungus that turns ants into zombies. It never gets old!
