This year, Earth Day, April 22, falls on a Saturday, therefore, we will webcast on Friday, April 20th. Some schools will be on holidays, but we hope to have classes participate live or with recorded material.

    • For additional information about how you can get involved in Earthcast as a presenter or a participant:
    • Sign up for an hour or half hour to webcast during the GMT day. It can be a pre-recorded session submitted prior to the day or a live session. (If you need someone to webcast for you, we can arrange it.)

Keep the spirit of Earth Day going, by participating in an EarthCast Echo!


The Earthbridges Community is happy to report that we're in the early stages of preparing for Earthcast, which is typically a live, 24 hour long global webcast that will take place on April 22nd, Earth Day. This is the 10th year (in 2017) in a row that the *Earthbridges community will be involved in the production of this event and we hope to build upon our successes of the past in many ways.

During Earthcast 08, Earthcast 09' Earthcast10, and Earthcast 11, we had contributions from people on many different continents broadcasting in several different languages. We hope to have even more participation from more people around the globe during the upcoming Earthcast.

We encourage people of all ages, backgrounds, and geographic locations to contribute to the project in some way, shape or form. A very simple way to participate is to help us promote the event; a more complex way to participate is to actually host a block of time. Listen to some of the archived content from previous Earthcasts by visiting our online community. If you're interested in investigating the various ways to contribute and participate, check out our "Ways to Participate" page.

Further project information, promotional materials, and news will be released and published over the next several weeks. In the meantime, feel free to leave a comment here or to use our contact information and links below to get in touch with us and learn more about how to contribute.

*The Earthbridges Community is a sub-community of the "Worldbridges" network. We appreciate the support of the Worldbridges community in helping us achieve the goal of creating an annual live webcast that coincides with Earth Day.
