Jon has written eleven books and produced/directed more than thirty documentary films. His feature documentaries include 'Dear President Obama,' 'Antarctica, on the Edge,' 'After the Spill' and 'Ghost Fleet.' ( He is a longtime contributor to magazines ranging from The New York Times Magazine and The Atlantic to Outside and Rolling Stone.

For the past eight years, Jon and his One Ocean Media Foundation / Oceans 8 teams have focused on a series of short films about the environmental risks facing and hopes for the Hudson Valley and Hudson River. Since 2018 he has hosted the weekly Green Radio Hour on Radio Kingston and for the past four years taught in the Environment and Urban Studies program at Bard College. Jon lives in New York's Hudson Valley and is the President of the One Ocean Media Foundation, Chairman of the Advisory Board of Adventurers and Scientists for Conservation and a Creative Affiliate with the Safina Center.

Dar Williams

Dar Williams has been called "one of America's very best singer-songwriters" by The New Yorker, writing songs and touring for over twenty-five years while drawing inspiration from her travels over four continents and from the Hudson Valley where she lives. She's released ten studio albums (eight with Razor & Tie Records) and clocked in over 2,000 gigs.

Known as much for her staunch progressive ideals as her raw acoustic energy, Williams has been captivating audiences with her sheer elegance and honesty in her folk-pop songwriting since the '90s. Williams' growth as an individual over her two-decade-long career has gone hand-in-hand with her evolution as an artist, touring along the way with such distinguished peers as Joan Baez, Patty Griffin, Ani DiFranco, Loudon Wainwright III, Shawn Colvin, Richard Shindell and Lucy Kaplansky among others.

Dar has also authored four books including her latest, "What I Found In A Thousand Towns," released in 2017 as well as two books for young readers. She has enjoyed teaching at the Rocky Mountain Folks Festival song school, Jorma Kaukonen's Fur Peace Ranch, Steve Earle's Camp Copperhead and in conjunction with the music programs at many high schools and colleges. Teaching an undergraduate course at Wesleyan University about music movements and democracy renewed Dar's faith in the importance of making music and also in the intrinsic, life-affirming value of creating songs, a process she is excited to be sharing in her neck of the woods.
