A still from the film, "Eating Alaska"

The Wild and Scenic Film Festival -- for activists, by activists -- is naturally a West Coast baby. But some of the group's best films have gone out on tour, and they were quite a hit when they came to Chester County about a year ago.

Now, some of the tour films are going to be shown this Saturday, Nov. 15, at the Academy of Natural Sciences in Philadelphia. The Academy is teaming up with Greener Partners, an organization that promotes farming, large and small, within the greater Philadelphia region.

The event will be from 3:30 p.m. to 7:30 p.m., and the $35 admission includes a selection of short films from the Patagonia Wild and Scenic Collection, plus refreshments, live music (by the bluegrass band, "The Treats") and a raffle with sustainability-style prizes. 

In addition to supporting Greener Partners, proceeds also will support the Academy's Center for Environmental Policy, including its popular public science programs like Town Square -- more than 100 of these alone in the past five years. 

Speaking of which, tonight's program, from 6 to 8 p.m., is a federal policy briefing on climate change.

Nov. 17 brings a talk by polar explorer Lonnie Dupree, who earlier this year led a team of explorers on a 54-day trek to the North Pole.

The program Nov. 19 is an Urban Sustainability Forum on transportation reform. How apropro, in light of the SEPTA strike. All are free.
