Explanation:

Jacob Riis was a police reporter in New York. In 1888, Riis took pictures of what life resembled in the city's ghettos. Utilizing his very own photographs just as photographs accumulated from different picture takers, Riis started to give addresses titled, "The Other Half: How It Lives and Dies in New York," in which he would demonstrate the photos on a projection screen and depict for watchers what the circumstances resembled. He gave his addresses in New York City churches.

Riis accused the poor living conditions for eagerness and disregard from society's wealthier classes and approached society to remedy the situation as an ethical obligation.
