--Earth Day New York Names Planet Green Official Media Partner for 2010--

(New York, NY) - Planet Green - television's destination for conscious living - is introducing EARTH MONTH, a multiplatform celebration of the 40th anniversary of Earth Day, with elements on-air, online and in the community. Throughout the month of April, Planet Green will highlight the innovators at the forefront of the sustainable living movement by offering all-new compelling programming, including the world premiere of TREEHUGGER TV, season three of network favorite WA$TED and the U.S. premieres of two notable documentaries. EARTH MONTH also will offer extensive original online content at Planet Green's leading Web destinations, PlanetGreen.com and TreeHugger.com. Around the New York metropolitan area, April will bring an enhanced presence for Planet Green, as the network has been named an official media partner for Earth Day New York.

"Central to Planet Green's mission is a steadfast reverence for the planet and a deep passion for conscious living," said Laura Michalchyshyn, President and General Manager, Planet Green, Discovery Health, FitTV, PlanetGreen.com and TreeHugger.com. "With EARTH MONTH, we're communicating that sustainability is about daily living and is something we should think about all year, while celebrating Earth Day on April 22. By presenting diverse, entertaining programming and informative on-line offerings, Planet Green is seeking to inspire our audience to take action and trigger lasting change."

On Tuesday, April 20, at 8 PM (ET), Planet Green will debut TREEHUGGER TV, the first installment of an all-new four-part series inspired by the online lifestyle brand. Comedian Faith Salie leads viewers through each 30-minute episode, presenting an irreverent and provocative look at pressing topics from around the globe - everything from air quality, to exopolitics, to the unexpected value of time capsules. Through these stories, TREEHUGGER TV will deconstruct and redefine the meaning of the word "treehugger" from the crunchy-granola stereotype to describe an innovative, adventurous change-agent working to create a better tomorrow.

EARTH MONTH also will feature programming from VERGE, Planet Green's all-new primetime programming block, including the all-new series FUTURE FOOD, on Tuesdays at 10 PM (ET). FUTURE FOOD follows the two most dangerous creative minds in modern cuisine, Moto Restaurant's Homaro Cantu and Ben Roche, as they go between the kitchen, the laboratory and the streets of Chicago in an effort to discover the dishes of tomorrow. VERGE will also air a special episode of 30 DAYS: OFF THE GRID on Monday, April 19 at 9 PM (ET), chronicling the journey of two 30-year-old American professionals who uproot themselves and move to an "eco village" in Missouri to live 100% off the grid. As part of Planet Green's new 24-hour daily programming schedule, VERGE airs seven days a week, from 8 PM through 11 PM (ET), repeating on the West Coast.

On Wednesday, April 21, at 8 PM (ET), viewers can turn to VERGE for the world-premiere third season of WA$TED. In the Planet Green original, actress, author and activist Annabelle Gurwitch proves that American homeowners can adopt healthier, environmentally-friendly lifestyles - and save money at the same time.

EARTH MONTH's programming slate also will feature the U.S. premieres of two notable documentaries:

� THE AGE OF STUPID

U.S Premiere on Saturday, April 17 at 10 PM (ET)

Oscar-nominated actor Pete Postlethwaite (In the Name of the Father, Brassed Off, The Usual Suspects) stars as an old man living in the devastated world of 2055. After watching "archive" footage from 2008, he is left with one burning question: Why didn't we stop climate change when we had the chance? THE AGE OF STUPID is directed by Franny Armstrong.

� THE SUZUKI DIARIES

U.S. Premiere on Monday, April 19 at 10 PM (ET)

THE SUZUKI DIARIES follows legendary environmentalist David Suzuki and his daughter Sarika on a road trip throughout Europe as they explore what a sustainable future might be like. Together, David and Sarika find ideas, innovation and inspiring individuals who prove that sustainability does not have to mean sacrificing quality of life. THE SUZUKI DIARIES is produced by Canadian Broadcasting Corporation.
