The San Francisco Green Film Festival describes itself as "the West Coast’s leading destination for films and events that spotlight the world’s most urgent environmental issues and most innovative solutions." This year's fest, themed "Water in the West," boasts 60 new films over its run through June 4. The fest opens tonight with a swanky reception and a local premiere, both in quite the watery setting!

Tonight at the Aquarium of the Bay, you'll "meet guests, filmmakers and aquatic life" (is it bad that the latter sounds the most fun?) "while enjoying local, sustainable food and beverages." Then you'll settle in for the SF premiere of DamNation (it's a pun!), the award-winning documentary on how dam removal might be the key to save our streams and rivers.

And you're not done yet! After the screening, there'll be a discussion and Q&A with DamNation's filmmakers Ben Knight, Travis Rummel, and Matt Stoecker.
