Why did people think temperance is a problem that needed to be fixed?

The Temperance Movement was an organized effort during the nineteenth and early twentieth centuries to limit or outlaw the consumption and production of alcoholic beverages in the United States. Temperance advocates encouraged their fellow Americans to reduce the amount of alcohol that they consumed.
