With the emergence of the industrial Revolution, many
changes were made in the living patterns of people in the cities. More people started to migrate to the cities
for better opportunities. As a result
livelihood started to shift from farms to factories. Unfortunately with mass migration came
overpopulation. Many of those who
traveled to the cities were now living in cramped living quarters and tried to
make the most of it. One of the negative
changes was the increase in pollution especially in air and water. Rivers started
to filled with trash and refuse from factories and from residents who live in
the cities. Polluted water and poor
living conditions also led to emergence of diseases like tuberculosis. This prompted the government to improve the
sewage and treating the water supply as well banning tenements.
