Re: Easy answer.
"And look at the mess they have caused."Motor cars solved the mess problem.
"The main problem, however, was manure. A horse produces between 7 and 15 kilos of manure daily. In New York in 1900, the population of 100,000 horses produced nearly 1,200 metric tons of horse manure per day, which all had to be swept up and disposed of. In addition, each horse produces nearly a litre of urine per day, which also ended up on the streets.....
Writing in the Times of London in 1894, one writer estimated that in 50 years every street in London would be buried under nine feet of manure."
