The 2025 Senate Joint Resolution 17, introduced on March 14, 2025, by a group of senators and cosponsored by numerous representatives, aims to honor April 22, 2025, as the 55th anniversary of Earth Day. This resolution highlights the significance of Earth Day, which is celebrated globally to promote environmental conservation and the protection of natural resources such as land, water, and air. It acknowledges the founding of Earth Day by U.S. Senator Gaylord Nelson of Wisconsin in 1970, who sought to raise awareness about environmental issues and mobilize public support for clean air and water.

The resolution reflects on the historical impact of the first Earth Day, which engaged 20 million Americans and led to significant environmental legislation, including the National Environmental Policy Act and the Endangered Species Act. It emphasizes the ongoing importance of Earth Day, which is now celebrated in 193 countries, fostering civic engagement and community collaboration for a sustainable future. The Wisconsin Legislature encourages residents to participate in Earth Day events and continue efforts to preserve the environment for future generations.
