One goal held by some advocates of the Progressive Movement was to promote conservation.

Explanation:

The Progressive Era is the name given to a period in US history from the 1890s to the 1920s. It was an era in partial rupture with the laissez-faire and individualism of the previous period, marked by economic, political, social and moral reforms in response to the changes and problems brought about by the industrial revolution: the disappearance of a social life organized around small communities, instability resulting from the anarchic development of industry, commerce, business, big cities and massive immigration.

The progressive movement took root at the local level before progressing at the state and federal level until the formation of an ephemeral "progressive party" whose candidate was Theodore Roosevelt in 1912. Like their opponents, the progressive reformers were largely majority of the middle classes.  

Some key reforms, such as women's voting rights, date back to that time, but the era of progress did not benefit all citizens, including minorities, and reforms did not always expected beneficial effects. Some policies, such as prohibition, were a resounding failure.
