The 19th annual Environmental Film Festival is about to get underway (March 15-27) in Washington, D.C., beginning a two-week showcase of 150 documentary, feature and animated films from 40 countries. The Festival screenings — at dozens of theaters across the city -- typically draw big crowds, and help to raise public awareness of a broad array of environmental issues. A special focus this year is the Energy Film Series, a diverse collection of international documentaries about our quest for energy and the challenge that poses to our fragile environment.
