I know there was an article in the Scientific American around that time
about air pollution in the form of airborne dust consisting of dried
horse dung pulverized by iron-shod hooves and wheels. It said that the
health consequences where becoming so serious in NY that it would
certainly limit future growth of the city and might even result in a
decline of density and level of activity, thus defining the upper limits
of urban growth. I saw a summary some years ago in the '100 Years
Ago.....' column of SA.

I don't recall the author, but there was an estimation paper published in the
late 1800s predicting that at the (then) current rates of growth, New York City
would soon be largely devoted to the care and feeding of horses (the primary
source of motive power then), and that the streets of NYC would all be five
feet deep in compacted manure. Only the arrival of the horseless carriage
averted this looming ecological disaster.
