The Progressive Era Conservation Movement was a social movement taking place during the late 19th and 20th century that saw a resurgence in environmental conservation following the drastic exploitation of natural resources in the United States. Supporters of this movement included President Theodore Roosevelt who created state entities to preserve natural resources and lands.
The Hetch-Hetchy debate discussed the incorporation of water resources into San Fransisco's city planning, specifically the damming of an important river in Yosemite in order to grow the new city or the conservation of wild lands. Congress debated the issue, pitting conservationists and preservationists against one another, eventually, conservationists were victorious seeing a dam built in the Hetch Hetchy Valley.
Later groups of immigrants, like the Italians, Polish, and the Jewish were treated very poorly when they came to the US in the 1900s. Many immigrants were funneled into urban ghettos, areas with poor living quarters resulting in high levels of death and disease. By the 1920s, the United States was reeling from its involvement in World War I and entered a period of isolationism. This was marked partly by a withdrawal from world affairs, but also a negative view on immigrants entering the country. In the early 1920s, the US passed the Immigration Quota Act which restricted the number of immigrants allowed to enter the country. President Warren G Harding's election based on a "return to normalcy" reflected the idea that Americans disliked immigrants who maintained cultural and linguistic ties to their homelands.
