The Horse and the Urban Environment

It’s easy to forget that car exhaust was a big improvement. From The Horse and the Urban Environment:

While the nineteenth century American city faced many forms of environmental pollution, none was as all encompassing as that produced by the horse. The most severe problem was that caused by horses defecating and urinating in the streets, but dead animals and noise pollution also produced serious annoyances and even health problems. The normal city horse produced between fifteen and thirty-five pounds of manure a day and about a quart of urine, usually distributed along the course of its route or deposited in the stable. While cities made sporadic attempts to keep the streets clean, the manure was everywhere, along the roadway, heaped in piles or next to stables, or ground up by the traffic and blown about by the wind.
