In nature we are surrounded by neutrality. One cannot say it is positive or negative. There are no advertising pitches; no billboard by the waterfall. In capitalism, we are surrounded by stupid stuff. I mean come on. There are a lot of stupid advertisements, on the radio. Public taste might determine which songs are hits. Consumer preference certainly does account for the success of R.E.M. or Nirvana. But no one voted for the goddamn billboards or other scams thrown at us by narrow-minded businessman (make that plural). After every one or two songs, we hear from the true mediocrities of the world. That amounts to being surrounded by the negative. I don't want a bite of candy, then a bite of cow dung or garbage or moldy orange rind, every other bite. I would settle for neutral.
But the city is not neutral It's polluted (here you insert a link to Pollution/City, the post for May 25th: but I am unable to make it link properly)
So are the airwaves.
