Earth Day and Arbor Day events


Contribute, connect, and celebrate

Every Earth Day, our community is inspired to act together to protect the natural resources that make Hennepin County a special place to call home.

Our Earth Day 2026 video showcases those natural resources and the actions the county and residents take to protect them.

Protect the Mississippi River

Partners across the Twin Cities are raising awareness about the progress that has been made to restore the Mississippi River through the Sacred Water, Shared Future campaign.

In 1926, the Mississippi River was declared effectively dead in the Twin Cities. A century of collective action brought it back to life, and this movement is celebrating that progress and inspiring the next 100 years of stewardship.

A variety of river-focused events, activities, and programs, are happening throughout the year, including the River Days of Action from June 1 to 15.
