As the cherry blossoms bloomed in our nation’s capital, Washingtonians knew that spring had arrived. And soon after, the softly falling petals signaled the imminent arrival of another iconic event: Earth Day.

Proposed in Congress by former Senator Gaylord Nelson (WI), Earth Day created public support for the founding of the Environmental Protection Agency under President Nixon and for landmark environmental laws including the Clean Air Act, the Endangered Species Act, and the Water Quality Improvement Act. The annual event celebrates our environment and elevates public consciousness about pollution and climate change.

We wanted to share some of the Earth Day festivities happening in Washington, D.C., and around the world this weekend. These are just a handful of the many great events taking place, but we think they really capture the spirit of Earth Day!
