The wilderness can teach more about what it means to be human than perhaps any place else. It consumes every one of your senses in vivid and profound ways (especially smell, which goes largely unused in day to day living – with the exceptions of generally bad food and farts).
This experience has been turned into a luxury – only for the very poor, or the very rich, depending on your geography. For most Americans, it is a vacation activity – something separate from daily life, and often financially unattainable. This is backwards.
Connection and access to nature are fundamental to experiencing your humanity to the fullest degree.
