The survival of wilderness -- of places that we do not change, where we allow the existence of creatures we perceive as dangerous -- is necessary. Our sanity probably requires it. These places function, whether we intend them to or not, as sacred groves -- places we respect and leave alone, not because we understand well what goes on there, but because we do not.
To the dull mind nature is leaden. To the illumined mind
the whole world burns and sparkles with light.
