In the United States, the end of the Vietnam War in 1975 led to widespread protests and a shift in public opinion about government involvement in foreign conflicts. The decade also saw the rise of the environmental movement, highlighted by the first Earth Day in 1970 and the establishment of the Environmental Protection Agency. Culturally, the 1970s was known for its diverse music scene, including the popularity of disco, punk rock, and hip-hop. Television shows like M*A*S*H and Saturday Night Live became iconic, reflecting the era's humor and social issues. Fashion trends included bell-bottoms and platform shoes, symbolizing the vibrant and sometimes rebellious spirit of the time.
