Concern over environmental problems first began to engage
public opinion in the United States during the
1950s, when high pollution levels in major cities such as
Los Angeles, Chicago, and Pittsburgh, combined with
the popularity of Rachel Carson’s book, Silent Spring,
aroused concerns over the impact that unfettered industrialization
was having on the quality of life and the
health of the American people. During the next several
decades, federal, state, and local governments began to issue
regulations directed at reducing smog in urban areas
and improving the quality of rivers and streams throughout
the country. In general, most Americans reacted favorably
to such regulations, but by the 1980s, the environmental
movement had engendered a backlash as some
people complained that excessively radical measures
could threaten the pace of economic growth and a loss of
jobs in the workforce. By the end of the century, concern
over the environment was deeply entangled with concerns
over the state of the national economy. Still, it was
clear that the quality of life in environmental terms was
much improved for the vast majority of Americans compared
to what had existed prior to World War II.
