How to Save the World last month won the award for best nonbroadcast film at the Jackson Hole Wildlife Film Festival, an international event where other winners came from the BBC, Animal Planet and the Discovery Channel. Tonight, the awardwinning documentary about biodynamic farming will be broadcast — premiering on MVTV.

The filmmakers were on the Island last month to interview Vineyard author William E. Marks for their next film, which is about water. Mr. Marks facilitating the right to screen the film, which begins tonight at 8 p.m.

The film shows marginal farmers in India reviving biodynamics, an arcane form of agriculture, with the help of an elderly New Zealander they call the new Gandhi.
