Last night marked the opening of the second annual SF Green Film Festival with the premiere of Island President, the work of Bay Area filmmaker Jon Shenk. The doc follows former Maldives president Mohamed Nasheed (he was forced to resign on Feb. 7) for two years and tracks his efforts to fight the already devastating effects of climate change on his country. Your next chance to catch the film is March 20 as part of the SF Film Society's Global Threats Film Series before it's released at Landmark Theatres Embarcadero Center Cinema on April 6.

The festival runs through Wed. 3/7 and includes a diverse mix of short and feature-length films. Also on the bill: local filmmaker Tiffany Shlain's Yelp: With Apologies to Allen Ginsberg's Howl which lampoons the addictions of our generation; Taste the Waste, a look at the startling reality of global food waste; Who Bombed Judi Bari? about an Oakland activist who sustained debilitating injuries after being violently targeted for her work; Blood in the Mobile takes us inside a militia-controlled mine in the Democratic Republic of Congo that produces a tin oxide used in cell phones at the cost of human lives; and Emily James' closing night film Just Do Itabout a group of environmental activists fighting capitalism in a way that recalls the current Occupy movements. Check out some of the film trailers below.
