The San Francisco Green Film Festival closes on Wednesday, April 26 with a screening of Rancher, Farmer, Fisherman: Conservation Heroes of the American Heartland at the Castro Theatre, co-presented by the IOFF.

Based on the book by Miriam Horn, New York Times best-selling author and co-producer of the film, Rancher, Farmer, Fisherman takes us down the Mississippi River all the way to the Gulf of Mexico. Along the way we're introduced to "unlikely conservationists," those who might not fit the mold of typical environmentalists yet are intimately familiar with and passionate about saving natural resources. 

The film screened at Sundance this past January. Watch the trailer.

Stick around after the screening for a book signing with Miriam Horn on the mezzanine at the Castro Theatre.
