Nature has no doors. It never has. That is part of its beauty and mystery. It does have borders, visibly separating land from water or forest from plain. Less visible ones separate ecosystems and habitats. But doors as such are not needed. Nature and its internal divisions are self-regulating and self-sustaining. Doors are a human invention, created for and used by us. They separate rooms, nations and peoples. They keep out undesirables, including the cold and outside threats. But doors are not walls; we open them to let in the good.
