The Sierra Club is launching its own television series, teaming up with filmmaker Robert Greenwald to tell stories about individuals and communities fighting for environmental justice.

"Sierra Club Chronicles" is a half-hour show that will air monthly. It is scheduled to premiere Thursday night on Link TV, which is available on DirecTV and the Dish Network.

The series is the first television venture by the nation's oldest and largest environmental organization.

The first of seven episodes is called "9/11 Forgotten Heroes." It tells the story of firefighters, construction workers and emergency medical personnel who continue to suffer from health problems from contamination at Ground Zero and must fight the government for health benefits.
