The environment is so important and it’s also very much in danger. We know this.

But we don’t know enough. This coming Earth Day will give Philadelphians a chance to learn more with a four-day film festival featuring environmental documentaries from around the world.

The inaugural Philadelphia Environmental Film Festival, taking place April 20 to 23 at the Prince Theater, hopes to become a “regional platform for dialogue about environmental issues” with a slate of films from around the world that will bring together folks who are passionate about the environment and film.

The festival is sponsored by The Nature Conservancy and supported by the Greater Philadelphia Film Office.

“The response from filmmakers around the world has been amazing,” said artistic director Alexandra Drobac Diagne in a statement. “Our jury is currently reviewing more than 200 engaging films from more than 30 countries. The Festival has tapped into a global passion.”

Festival organizers are still taking submissions.
