In this world full of countless creatures with powers which humans can only begin to approach, Man has often defined itself in opposition to non-legendary pokemon in its ability to shape its environment. Even this self-image is a fragile one – Sinnoh's philosophers have often pointed out that Bibarel build dams – but until the discovery of Unova, agriculture was known only to humans, and it served as the basis for many justifications of human mastery of the world.
And then the world discovered the Pinwheel and Lostlorn forests, filled with troops of Panpour watering trees with their tails. At first, humanity grasped at straws, suggesting first that they were using water to hunt for insects, then that they were not watering it to grow the plant, but to make it easier to digest. But with each research effort, another excuse fell away, until it finally became clear that the whole of both forests had been painstakingly created by the Panpour themselves as a source of reliable food.
Tragically, as more and more Panpour were captured – for once humanity accepted the truth, they realized that a pokemon which can water plants is very useful on a human farm - the forests themselves began to diminish. Pokemon trainers soon began to fear for the many rare pokemon that had been drawn to these miniature ecosystems created by Panpour agriculture, which some even likened to a natural zoo. In time, some exchanged their regular outfits for a pokemon ranger's gear, and began regular patrols to prevent any unauthorized Panpour catching, in order to preserve the forest these pokemon had built.
Man is distinguished from pokemon today only in that it can not be captured in any sort of poke ball.
