The 2025 Assembly Joint Resolution 19 honors April 22, 2025, as the 55th anniversary of Earth Day, a global event dedicated to environmental conservation and the protection of natural resources. The resolution highlights the origins of Earth Day, founded by U.S. Senator Gaylord Nelson of Wisconsin in 1970, which aimed to raise awareness about environmental issues and mobilize public support for clean air and water. The first Earth Day inspired 20 million Americans to advocate for environmental solutions, leading to significant legislative advancements in environmental protection.

The resolution emphasizes the continued importance of Earth Day, which is now celebrated in 193 countries, fostering civic engagement and community collaboration to ensure a sustainable future. It calls on the people of Wisconsin to participate in events and actions that promote environmental stewardship, reinforcing the commitment to preserving the planet for future generations.
