About Earth Day
In 1962, Rachel Carson’s bestselling book “Silent Spring” raised the specter of the dangerous effects of pesticides on America’s countryside. Until that time, protecting the planet’s natural resources was not part of the national political agenda. Factories pumped pollutants into the air, lakes and rivers with few legal consequences. Big, gas-guzzling cars were considered a sign of prosperity.
Throughout the 1960s, Senator Gaylord Nelson, a Democrat from Wisconsin, developed the idea for Earth Day after being inspired by the anti-Vietnam War “teach-ins” that were taking place on college campuses around the United States. He envisioned a large-scale, grassroots environmental demonstration raise awareness about environmental issues and transforming public attitudes. In the fall of 1969, Nelson announced the Earth Day concept at a conference in Seattle and invited the entire nation to get involved.
The first Earth Day on April 22, 1970. The event activated 20 million Americans from all walks of life and is widely credited with launching the modern environmental movement. Throughout the 1970s, a number of important pieces of environmental legislation were passed, among them the Clean Air Act, Clean Water Act, and Endangered Species Act. More info: Earth Day | US EPA
