Creation of Earth Day


In the 1960s the effects of pollution and environmental damage became more visible. Passionate environmentalists wrote on environmental themes. Vietnam war protests energized people looking for change. President Richard Nixon signed the National Environmental Policy Act of 1969. U.S. Senator Gaylord Nelson wanted to bring this growing environmental consciousness to the public. Nelson thought that "teach-ins" would be particularly effective. The first Earth Day celebration on April 22nd, 1970 was co-chaired by congressman Paul N. McCloskey and coordinated by Denis Hayes. The first Earth Day was successful nationally. Since 1970, the event has been celebrated worldwide and grown to include issues around climate change.

To learn more, consider the Earth Day Research Starter. Research Starters are sources that help you get caught up on a topic. They can help you learn language specific to a subject area, understand how you can narrow a topic if needed, and learn about the general details of an event or topic. They help you be better prepared for the next step of research, where you'll find or analyze sources for your project. Generally speaking, research starters and other background sources contain information that is too general to be used as evidence for your projects. (Please note, encyclopedias/tertiary sources should NOT be cited in your assignment.
