Air is traditionally 'thin,' but the more we learn about our atmosphere, the more substantial it becomes. In some places it is so filled with inorganic flotsam that it is almost thick enough to plough; in others, it has become so primed with the by-products of life that it comes close to being a living tissue in its own right.

We share our planet quite naturally with a permanent aeroplankton; a buoyant ecology too soft to hear, too small to see, but heavy with mood and meaning. Imagine being aware of all these airy inclusions - and you can begin to understand how it might feel to be able to smell really well.

I doubt very much that the chief executives of any of the Fortune 500 corporations can name five edible plants, five native grasses, or five migratory birds within walking distance of their homes, or name the soil series upon which their house sits. And I would contend that if you don't know where you are, you are in fact nowhere at all.
