April 22, 2020, marks 50 years of Earth Day. The first Earth Day in 1970 sparked the passage in the U.S. of the Clean Air, Clean Water and Endangered Species acts, and the creation of the Environmental Protection Agency.

Today, the urgency has never been greater, and the stakes have never been higher, as we face both the coronavirus pandemic and a slowly building climate disaster.

Here are three ways you and your students can get involved as Earth Day goes digital:

Join the global digital surge. Over the 24 hours of Earth Day (12:01 am ET – 11:59 pm ET on April 22), Earth Day Network will flood the digital landscape with global conversations, calls to action, performances, video teach-ins and more.

Watch Earth Day Live. Tune in to Earth Day Live April 22-24 to watch, discuss and participate in a livestream featuring stories, performances and opportunities for digital collective action. It will be the largest online mass mobilization in history. You can also tune in to Earth Day Live at EcoWatch.

Take 24 hours of action. With a new call to action every hour, Earth Day 2020 will drive actions big and small, give diverse voices a platform, and demand bold action for people and the planet.
